QRP DX: Pairing the MM0OPX EFHW & Icom IC-705 during an impromptu activation

8 Comments

Turns out, if you go to Canada for nearly two months, when you return home you’re going to have about two months worth of catch up.

It’s all explained in one of Einstein’s theories. If memory serves, Einstein stated:

“One cannot simply ignore stuff for two months and expect no repercussions. Time lost must be accounted for due to the principles of the conservation of energy. Plus…what in creation were you thinking?”

When we returned from Canada in early August I had some pretty big plans about the parks and (especially) summits I would hit here in North Carolina. But after returning, I quickly realized I had so much work to do around the house and a number of DIY jobs I’d postponed at our investment property. They all immediately took priority.

Indeed, in the one month span after returning from Canada, I only performed three park and no summit activations. There was a three week period of time without activations of any sort. I simply didn’t have the time to fit anymore in my schedule. This all gave me a serious case of activation withdrawal.

If you’ve been following my field reports, you’ve no doubt noticed that I never do multi-hour activations at one site unless I happen to be camping at a POTA park.

I’m asked about this fairly regularly (why I don’t do longer activations to achieve Kilo awards, etc.) but the truth is I make POTA/SOTA fit in my busy family schedule. This often equates to short (30-60 minute) activation windows.

Then quite often, I’m on the road or doing errands in town and realize I have a short opening for an activation, so I squeeze it into the day. This is why I always have a fully self-contained field radio kit in my car. At a moment’s notice, I can set up a station, and play radio.

In a way, I find this style of quick activation fun, too. “Can I seriously validate a park during this short window of time–?”

These activations remind me of that scene in A Christmas Story where the father gets a small thrill out of timing himself as he changes a flat tire on the side of the road. I totally get that.

Except with me it’s deploying antennas instead of managing lug nuts.

Hamfest time!

Friday, September 2, 2022 was a big day for me. On the way back from visiting my folks that morning, I spent a couple of hours at the Shelby Hamfest.

The Shelby Hamfest typically has the largest outdoor tailgate market in all of North Carolina and likely one of the larger ones in the southeast US. I had no items on my wish list, I just wanted to see what was there.

This was the first hamfest I’d attended in a little over a year. It was a lot of fun and I got to meet a number of friends and readers/subscribers.

If you’d like to see the treasure I found at the Shelby Hamfest, by the way, check out the large photo gallery I posted over on the SWLing Post.

Back to the topic of impromptu activations…

South Mountains State Park (K-2753)

Driving home after the Shelby Hamfest that early afternoon, I realized I was passing dangerously close to the Clear Creek access of South Mountains State Park.

I had a couple of errands to run back home before the post office closed at 17:00 that day, but in my head I believe I had just enough time for a quick activation. The total amount of detour driving would only be about 15 minutes; I’d just need to keep the activation (including most set up and pack up) under 45 minutes or so.

At the last minute, I took a right turn and headed to the park!

Fortunately, the one lonely picnic table at the Clear Creek access was unoccupied.

I grabbed my IC-705 kit and a new antenna!

The MM0OPX QRP End-Fed Half-Wave (EFHW)

A few weeks prior, Colin (MM0OPX) reached out to me and asked if I would consider testing a new high-quality, highly-efficient QRP EFHW he’d designed.

Of course, there’s nothing new about an EFHW–it’s one of the most popular field antenna designs on the planet–but Colin’s goal was to make one with the lowest insertion loss possible in a compact, lightweight (50g), and durable format.

I say he succeeded.

In fact, this activation was actually the second one where I used Colin’s QRP EFHW. The previous day, I paired it with a then very Beta version of the Penntek TR-45L at Tuttle Educational State Forest (K-4861).

In short, the antenna made for a wildly successful QRP activation. Here’s the QSO Map (you’ll need to click and enlarge to see the number of contacts):

QSO Map from the previous day with the MM0OPX QRP EFHW

The Penntek TR-45L was still quite new at the time and even though  I got John’s (WA3RNC) blessing, I didn’t post the activation video and mini overview on YouTube. Keep in mind the TR-45L was still in Beta so not all features had been finalized.

I did, however, post the entire TR-45L activation video on Patreon.

Quick side note: Why this video only on Patreon?

As I mentioned in a previous post, I’ve now invested in a Pro account with Vimeo that allows me to post completely ad-free videos  that my Patreon supporters can enjoy and even download. I recently discovered that YouTube unfortunately inserts ads even though I have monetization turned off. I pay for Vimeo’s bandwidth and server space, so I also can control the ad experience completely (basically eliminating any possibility of ads!).

My Patreon supporters are the ones making it possible for me to pay the annual $420 fee to Vimeo and I am incredibly grateful, so I pass along the benefit to them.

The FX-4L QRP SDR HF transceiver is on order!

49 Comments

This year, I’ve had a couple of readers very kindly offer to loan me their FX-4C transceivers to take to the field and review.

Those offers have been very temping because I’ve only heard positive comments from owners of this wee feature-packed SDR transceiver designed by Yu (BG2FX).

Earlier this year, I learned that Yu was retiring the FX-4C and would be introducing two new radios, so I decided to hold off on an FX-4C review for this reason.

My buddy, Don, informed me that the new radios were now available for pre-order, so I checked out the option on Yu’s website, and placed an order.

Details (features and specs) are still a little sparse because BG2FX is still finalizing the design and lining up production, but here’s a snapshot of the two models based on Yu’s preliminary info:

The FX-4CR

I was very pleased to read that my buddy John (AE5X) has one of these on order.

The FX-4CR can push 15-20 watts on most bands according to John, which is most impressive for a one pound radio that fits in the palm of your hand! It covers 80 – 6 meters, sports a color screen with a 48 kHz wide waterfall display, an internal sound card for digital modes, built-in speaker and microphone, 9 – 18 VDC input range, and even sports Bluetooth!

That’s an impressive array of features for $550 US (on pre-order).

The FX-4L

I pre-ordered the FX-4L and am told by Yu that it should ship by end of October or early November 2022. I wouldn’t be surprised if that’s an optimistic projection.

The FX-4L is essentially a more basic QRP version of the FX-4CR; it’s maximum output power is around 5 watts.

It’s very similar to the FX-4CR in many respects: it has the same display from what I can tell, covers 80 – 6 meters, has a wide voltage range 9 – 18 VDC, sports an internal sound card, and is super compact and lightweight.

The FX-4L doesn’t appear to have Bluetooth. Lu doesn’t mention a built-in speaker or microphone, but there’s an obvious speaker grill and even a small hole that might be a microphone. I’ll try to confirm this. Yu does note that there’s room in the chassis for the user to add a battery or ATU.

I’ve been more interested in the FX-4L because, as you likely know, it’s very rare for me top operate over 5 watts of power.

That said, I certainly see the appeal of a 15W+ radio like the FX-4CR.

(Many thanks to Yu for sharing all of the FX-4L photos above.)

Stay tuned!

I’m really looking forward to checking out the FX-4L and also reading AE5X’s assessment of the FX-4CR.

I’m curious if anyone else has pre-ordered one of these radios. Also, if you’re an FX-4C owner, I’d love to hear your comments!

The New Penntek TR-45L: A Video Tour/Overview, then a full POTA activation!

16 Comments

Yesterday, John (WA3RNC) opened orders for his long-awaited Penntek TR-45L 5 band, CW-only, QRP transceiver.

As I mentioned yesterday, I’ve had the pleasure of helping John beta test this radio for the past month. In that time, I’ve gotten to know the radio from the inside out and have even taken it on a few POTA activations. In fact, with John’s permission, I just posted my first TR-45L activation video for Patreon supporters yesterday. The radio was using an early firmware version in that video.

TR-45L Video Tour and Overview

Yesterday, after an early morning appointment, my schedule opened up; a rarity in my world.

I then got the idea to take the TR-45L out to a park, do a full video overview of its features, then put it on the air in a POTA activation.

Hazel loved this idea too.

So I packed the TR-45L, a log book, my throw line, and two 28′ lengths of wire. Hazel jumped in the car before I could invite her.

I’ve used a wide variety of antennas on the TR-45L over the past weeks, but I hadn’t yet performed a park activation only using two lengths of wire and relying on the TR-45L’s optional Z-Match manual antenna tuner. This would make for a great real-life test!

Quick note about video timeline

Side note for those of you who follow my field reports and activation videos…

I pushed this video to the front of the line since the TR-45L just hit the market. I wanted to give potential buyers an opportunity to see and hear this radio in real world conditions thinking it might help them with their purchase decision.

I’m currently about 7 weeks behind publishing my activation videos. Much of this has to do with my travel schedule, free time to write up the reports, and availability of bandwidth to do the video uploads (I’ve mentioned that the Internet service at the QTH is almost dial-up speed).

I was able to publish this video within one day using a new (limited bandwidth) 4G mobile hotspot.  Patreon supporters have made it possible for me to subscribe to this hotspot service and I am most grateful. Thank you!

So that I can publish this report quickly (this AM), I’m not going to produce a long-format article like I typically do. Instead, this is one of those rare times when the video will have much more information about the radio and the activation than my report.  I’ve linked to and embedded the video below.

Now back to the activation…

Yaesu FT-710 series on the horizon?

29 Comments

If you’re on any of the social media platforms and follow ham radio news, no doubt you’ve seen the photo above of a supposedly new Yaesu product: the FT-710.

The Yaesu FT-710 will cover 160-6 meters with 100 watts output.

There are two other variants: the FT-710M and FT-710S which are the Japanese market 50 and 10 watt versions respectively.

In terms of availability, DX-World reports that it’s scheduled to be released in late August 2022 and the price is still unknown. Click here for the source information (in Japanese).

I have no inside information from Yaesu about the FT-710, so I take this news with a grain of salt. That said, the information being shared here doesn’t look unreasonable and the prototype illustration looks legit.

The “late August” availability would conveniently coincide with the 2022 JARL Ham Fair.

I suppose the FT-710 would be a direct competitor to the venerable Icom IC-7300. I’m guessing this model’s price point will be somewhere between the FT-891 and the FT-DX10. It certainly appears to be more compact (weight is 4.5kg/9.2lbs).

If you’re like me, though, you’d love to see Yaesu release is a new QRP field radio! One to replace the insanely successful FT-817/818 series.

One can dream, right!?

The Elecraft T1 Protection Case by Tufteln

13 Comments

Long-time QRPer.com reader and supporter, Joshua (KO4AWH), runs an Etsy store with a wide range of products primarily designed for field operators. Over the past few months, Joshua has sent me various prototypes for feedback and also to test in the field. You’ll see some of his antennas in upcoming field reports and activation videos. I’m very impressed with his designs.

If you’re an Elecraft T1 owner, you should be especially interested in his T1 Protection Case.

Joshua sent me an early version of this clip-on case several months ago and it immediately replaced the simple cover I printed from a Thingiverse file. (To be clear, the Thingiverse case served me well for a couple years, but I prefer this one since it doesn’t require a rubber band to hold it on the T1.)

The Elecraft T1 is a hearty little ATU and I don’t worry about damaging it while tucked away in my SOTA pack, but the little buttons on the front are prone to be pushed with any amount of applied pressure. This can result in unintentional operation which can accidentally place it in bypass mode or at least shorten the life of your 9V cell.

The Elecraft T1 is not an inexpensive station accessory and, at the moment, they’re about as rare as hen’s teeth. The lead time on new T1s is counted in months rather than weeks (at time of posting, this is due to vendor board issues).

The Tufteln Protection Case simply snaps on the Elecraft T1 and protects the BNC connectors, ground point, and the front panel buttons.

The case material is durable and adds very little to the bulk of the T1.

Of course, you can’t operate the T1 with the case around it because the BNC connectors are covered, but I have propped up my T1 on the case while using it on rough concrete picnic tables. I’d rather the case be scratched than my T1!

If you own an Elecraft T1 and don’t have a protective cover, I’d encourage you to either print one, or buy Joshua’s T1 case. For years, I simply removed or reversed the 9V battery to keep the T1 from engaging while packed, but that doesn’t protect the buttons and (frankly) it’s a pain to pop the battery out and flip it for each use (then to remember to flip it back when packing away).

The Tufteln case is a simple and affordable ($16.50) solution!

Thanks for sending this to me, Joshua. I dropped my T1 while setting up my TX-500 for Field Day and it protected my favorite little ATU!

Xiegu G106 and D90: A few pre-production unit photos

8 Comments

I’ve a friend who works with a number of radio manufacturers including Xiegu. He recently took delivery of the new Xiegu G106 QRP transceiver and a Xiegu D90 USB-Radio Interface.

Based on the photo above, the G106 is even more compact than I originally assumed.

These are the accessories included in his G106 box:

Looks like the same cables and mic included in other Xiegu radio packages.

He also took delivery of the new Xiegu D90 expansion card:

Note that these units are very much early prototypes and don’t even have serial numbers. Nonetheless, he plans to take the G106 to Field Day today–I’m looking forward to hearing his report.

Xiegu G106 preliminary specifications and features

13 Comments

Xiegu distributor, Radioddity, has now publicly announced a product page for the new Xiegu G106.

No pricing/availability mentioned, but we do learn a few more details from their page.

Features:

  • The Xiegu G106 is a 5W SDR transceiver using 16bit-CODEC sampling
  • SSB, CW, AM modes are supported along with wide FM reception (for the FM broadcast band)
  • General coverage receiver
  • Three selectable CW bandwidths
  • Digital modes when connected to a computer with the Xiegu DE-19 interface

  • Transmitting frequency:
    • 3.5~3.9MHz
    • 7.0~7.2MHz [I assume this is incorrect]
    • 10.1~10.15MHz
    • 14.0~14.35MHz
    • 18.068~18.168MHz
    • 21.0~21.45MHz
    • 24.89~24.99MHz
    • 28.0~29.7MHz

  • Weight: about 720g (only host)

Radioddity notes: “The shoulder strap [above] is for display only. Final equipped accessories not decided yet.”

My G106 takeaways?

Based on Xiegu’s previous offerings, I would have to assume the G106 could be in production within a few months (supply chains/C-19 pending). It’ll likely be released with basic firmware and updated with time. It’ll be price competitive for sure.

I would hope that perhaps they’ve worked on the audio characteristics and noise floor of the G106. Previous Xiegu products have mediocre audio characteristics and a higher noise floor than my other transceivers. Let’s also hope the front end is more robust than the X6100.

At 0.37 Amps, current drain in standby/receive is a tad on the high side for late model QRP portable radios. Still, quite respectable for a field radio.

It doesn’t appear the G106 has an internal tuner, nor an internal battery unless they’ve simply omitted this from the features list.

It also doesn’t mention CW and/or voice message memory keying which I consider to be so valuable for park and summit activators. If history is an indicator, I suppose they could add this later in firmware updates.

Also, the Radioddity announcement mentions that the G106 covers “[t]ransmission and reception of all amateur frequency bands within 3.8~29.7MHz.” Yet in the specifications, they fail to list the 60M band and the 40M band is noted as 7-7.2 MHz. I assume the 40M band range is simply a typo–I can’t imagine it would actually stop at 7.2 MHz. I also imagine they may have simply omitted the 60M band channels. RX seems to dip as low as 0.5 MHz, thus covering most of the mediumwave broadcast band.

Truth is, these are early days for the G106 and we may learn that it has more features than listed here on Radioddity’s page.

If it does indeed lack an internal ATU and/or internal battery, I assume the price point would be well below that of the X5105 and X6100; my (complete and total) guess would be somewhere between $300-400 US.

I’ll post more info about the G106 as we learn more. I’ll also try to update and correct this post if I learned some of these details are incorrect.

Update: A few more details about the new Xiegu G106 QRP transceiver

20 Comments

Yesterday, I posted some photos of the new Xiegu G106 transceiver.

Since then, I’ve been getting a few updates from my friend as, I assume, Xiegu releases preliminary info.

This is the latest illustration (click to enlarge):

You can see Xiegu is certainly eyeing the park and summit activators out there.

They’re also touting digital mode operation and I’ll have to assume this means the radio has an internal sound card which would certainly simplify a field-portable digi mode kit.

I was originally told that the G106 had six bands, but this image implies 80-10 meters including the WARC bands. We’ll have to verify this once the production marketing information is released. Since this is the 2022 Hamvention weekend, we could be learning more int he next couple of days.

I’ll continue to post updates here on QRPer.com. Bookmark the tag G106 if interested.

Oh yeah, I do hope there are some fold-out feet or a bail hiding under that G106 chassis!
