Pairing my new Xiegu X6100 with a 31 foot speaker wire antenna (and avoiding RX overload)

Regular readers of QRPer.com might question the wording in my title since I’ve already posted several field reports and even a full review of the Xiegu X6100. So why would this X6100 be considered a “new” radio–?

Since I go over this in more detail in the activation video (linked and embedded below), I’ll give you the nutshell version here:

My activations with the X6100 early this year (2022) were all performed using a loaner unit sent to me by Radioddity. I kept that unit for a few weeks, shipped it on, and purchased one of my own.

In February, when I received the X6100 I purchased, I immediately noticed a small mechanical issue with the encoder.

This is the X6100 open. You can see the back of the encoder to the right of the ribbon cable.

I tried fixing it (with instructions received from Xiegu) but in the end had to return the transceiver for replacement.

The X6100 unit in this field report is my replacement–technically, the third X6100 I’ve had in my hands, and this was my first activation using it.

Many of you have asked why I haven’t taken the X6100 to the field more often this year and this is why. I basically didn’t have a functioning unit for most of February, March, and April. Radioddity was quite responsive to my issues with the X6100, but frankly I had a lot going on during that time frame so it took longer than normal to troubleshoot, modify, test, and send back the faulty unit.

Fortunately, the replacement X6100 has no encoder issues other than the brake is very tight. I’m not willing to break the warranty seal on this unit to adjust it, so I’ll just live with a much-tighter-than-I’d-like encoder.

[Update: Bob (W0BNC) points out that the tight brake is due to friction caused by a felt pad under the X6100 encoder knob. The remedy is to pull off the rubber ring around the encoder knob, loosen the set screw, lift the knob slightly off the body, and retighten. I’ll do this when I’m back with the X6100 after summer travels. Thanks, Bob!]

X6100 field kit test

This activation was also the perfect opportunity to test all of the components of a dedicated field kit I’m building around the X6100.

The kit consists of:

  • The Xiegu X6100 QRP transceiver,
  • a BNC binding post adapter,
  • paddles,
  • the X6100 battery charger,
  • a 31′ speaker wire antenna
  • 25 meters of 2mm throw line,
  • a weaver 8oz weight, and a
  • logging pad and pencil.

Everything, save the antenna, fits in my Red Oxx Hound EDC pack.

Eventually, I’ll replace the speaker wire with some thinner Wireman stuff and it should all fit in the Hound pack, albeit snuggly!

I’ve decided that the X6100 will live at my parents’ home in the NC foothills, so I’ll always have a field radio kit available while staying there overnight.

On May 9, 2002, an opportunity opened up in the afternoon to finally take my new X6100 to the field! Continue reading Pairing my new Xiegu X6100 with a 31 foot speaker wire antenna (and avoiding RX overload)

QRP POTA at Fort Dobbs: No antenna? No problem!

I’m a pretty organized field radio guy if I do say so myself.

In all of the hundreds of field activations I’ve attempted since the days of the National Parks On The Air (NPOTA) program, I’ve only arrived on site two or three times and discovered I was missing a key component of my field kit.  Out of those times, only once do I remember that the missing component prevented my activation (it was hard to power my radio without a battery and power cable). The other times, I was able to improvise.

As I mentioned in this two-parter series, I tend to build two different types of field kits:

  • one that’s fully self-contained (like the MTR-3B kit),
  • or one that’s modular, where component families (transceiver, antenna, power, etc) are in their own packs and can be moved from pack to pack.

I always prefer having dedicated field kits, but they’re pricey because they require a dedicated antenna, battery, radio, key/mic, earphones, pack, connectors, and sometimes even their own throw line.

I assemble modular kits around a particular radio and antenna system prior to leaving the QTH to go on an activation. I have a method for doing this which prevents me from leaving stuff behind.

Save this time…

On Thursday, April 7, 2022, before leaving the house for a quick overnight trip, I grabbed my SOTA pack and disconnected my Elecraft KX3 from the KXPA100 amp in the shack.

My pre-side rails KX3 in the shack.

My KX3 is used a lot in the shack–along with the Mission RGO One and Ten-Tec Argonaut V–it’s one of my staple rigs at the QTH. I didn’t think I would have time to complete an activation on this quick trip, but if I did, I wanted to use the KX3. I also grabbed one of my pouches that contained a 12V battery, distribution panel, and power cord.

Also inside the pack was my Elecraft KX2 kit. It was in there from a previous activation, so I just left it in the bag.

When a window of opportunity for a quick activation opened on Friday, April 8, 2022, I grabbed it. I didn’t have time to go far afield, so I chose to activate the closest park to where I was running errands that day.

Fort Dobbs State Historic Site (K-6839)

As I was driving to the site on I-40, it dawned on my that I might have forgotten to pack an antenna.

Not a good feeling, but I was only 10 minutes from the park, so there was no turning back.

You see, a couple days beforehand, I did a bit of an antenna inventory at the QTH–I took all of my antennas out of their packs, checked them over carefully for any damage or fault points and  made notes.

I normally keep a 20M EFHW antenna in my KX2 field kit, but I remembered that also I removed it during the inventory.

Once I arrived at Fort Dobbs, I opened my SOTA pack and confirmed that I had no antenna. Not a one.

I kept a clear head and realized that if I wanted to complete the activation, I needed to do one of two things:

  1. Search the car in case, somehow, I had a spare antenna floating around in there. Unlikely, but I’d feel like a fool if I aborted an activation with an antenna in the car.
  2. Go to a nearby hardware or dollar store and find some cheap wire.  The KX3 has a brilliant internal ATU to match pretty much any wire I connect to it.

So, I searched the car. Continue reading QRP POTA at Fort Dobbs: No antenna? No problem!
