[…]I came upon this interesting mount setup for the Yaesu FT-818 via Armando – KP4YO. I saw his setup on his QRZ page and was intrigued, as the rig seems to be able to stand up on its back side even with a pretty large whip installed.
Seems the gist of it is to bring all of the rear mounts and connections to the front.
The TPA pack frame provides a modular platform for configuring your Yaesu FT-817 and FT-818 into a quickly deployable base, mobile, field or mil style man pack configuration.
The concept was to design an effective, small form factor frame that when installed, would allow relocation of all rear inputs, minus power and ACC connection, to the front of the radio, provide standoff at the rear of the radio for permanent cable attachment, and also provide protection when used in the field.
The relocation platforms provide a sturdy mounting point for attaching commercial or mil type VHF/UHF whip antennas. All accessory mounts are interchangeable and can be oriented to suit your operating situation.
The TPA pack frame is a 2 piece frame that is secured to the radio via 8, side chassis mounts. The frame is CNC laser cut from 5052 aluminum and powder coated with a matte black finish. The TPA provides protection to the radio body and control head with a wrap around design while allowing access to the top oriented MODE and BAND buttons, as well as the battery compartment.
Thank you for sharing this, Phillip! I’ve never seen this pack frame/cage before and I’m not even sure how I’d use it for the type of field work I do, but I’m willing to bet that it’s the perfect solution for those wanting an uber-rugged cage for Emcomm and/or as a manpack. I love products like this that transform gear into military-grade kit!
Anyone out there use the TPA-817 B? Please comment!
On Monday, March 22, 2021, I performed three QRP field activations in one day. I started off the day with a visit to Three Top Mountain Game Land, and then headed to Mount Jefferson State Natural Area for a POTA and SOTA activation before heading to New River State Park.
When plotting my multi-site activation day, I picked Mount Jefferson because it’s a SOTA entity (W4C/EM-021). I only realized later that it’s also a POTA entity (K-3846). I mistakenly assumed Mount Jefferson was a county park rather than an NC state park. To do both a POTA and SOTA activation simultaneously is ideal!
Mount Jefferson (W4C/EM-021)
This was my first visit to Mount Jefferson and, frankly, I wasn’t sure what to expect in terms of hiking.
The park itself is amazing! North Carolina parks never let me down.
The entrance is near the base of the mountain and very close to the town of West Jefferson. The park road climbs up the side of Mount Jefferson –there are a number of spots to park, hike, and picnic.
I had not checked the trail map in advance, but I had read that the summit trail was accessible from the parking and picnic area at the end (top) of the park road.
I hopped out of my car, grabbed my SOTA pack, and very quickly found the trail head.
The trail is impeccably maintained and wide enough for vehicle use (no doubt these trails double as access for tower maintenance on the summit).
The hike to the summit from the parking are was incredibly short–about .3 miles. Normally, I’d want a much longer hike, but since I was trying to fit three site activations in a span of four hours, I didn’t complain.
On top of the summit, one is greeted by a typical cluster of transmission towers.
While I appreciate checking out antennas and towers, these are never a welcome site because they can generate serious QRM, making a SOTA activation difficult.
I searched around and found a spot to set up well within the activation zone but giving me a bit of distance from the towers.
My Yaesu FT-817ND was desperate to get a little SOTA action, so I decided to pair it with the Chameleon CHA MPAS Lite using the Elecraft T1 ATU to find matches.
After putting the FT-817 on the air, I was very pleased to hear that the nearby transmission towers and power lines weren’t causing any noticeable interference. This was a very good sign because, frankly, propagation was very unstable that day and I had real concerns about being able to work stations on 40 meters.
I hopped on the air and quickly realized I’d forgotten to hook my external battery up to the Yaesu FT-817ND. This meant I was running something closer to 2.5 watts as opposed to a full 5 watts. I decided to attempt the activation without the external battery and add it if needed.
I started operating on 20 meters and was very pleased to quickly rack up a number of contacts. I could tell that most of these contacts were via SOTA because I recognized the calls and primarily SOTA chasers.
Within 11 minutes, I worked 10 stations on 20 meters in CW. I was very pleased with how quickly those QSOs rolled in and how easily I logged the four needed for a valid SOTA and 10 needed for POTA activation–all on 20 meters.
Next, I moved to 40 meters where I worked two stations and 30 meters where I worked one. For sure, 20 meters was a much stronger band than 40 and 30 turned out to be.
After working 13 stations, I packed up.
Obviously, 2.5 watts was plenty for this activation!
I would have loved to stay longer, but frankly, I needed to stick to my schedule because I had one more park to fit in that day! (More on that in a future post and video!).
Here’s my QSOmap for the Mount Jefferson activation:
And here’s my full log:
Even though I was a bit pressed for time, I still made one of my real-time, real-life videos of the entire activation. I hope you enjoy:
Next up will be an activation of New River State Park. I hope to post this early next week.
Last week, I thoroughly enjoyed taking the Yaesu FT-817ND to the field.
While the ‘817 lacks features I’ve come to appreciate during field activations like voice and CW memory keying, it’s still an incredibly fun and capable radio.
Last Monday (January 18, 2021), I had an opportunity to visit Lake Norman State Park (K-2740) and perform an activation around lunchtime. Lake Norman is convenient to my hometown of Hickory, NC and these days I typically spend at least a couple nights there doing a little caregiving for my parents. It’s rare my schedule is clear at lunchtime to fit in an activation–typically it’s later in the afternoon.
As with my recent activation at Lake Jame State Park, I paired the Yaesu FT-817ND with my Par End-Fedz EFT Trail-Friendly 40/20/10 meter resonant antenna.
It was an incredibly fun activation and one of the few recently where I racked up some great QRP contacts across the 20 meter band before moving to 40 meters.
Here’s my QSOMap of the activation (red lines are phone, green are CW):
As with most of my activations, this one was relatively short. Rarely do I have more than 45-60 minutes of on-air time during a POTA sortie.
I also made another real-life, real-time, no-edit video of the entire activation. If interested, you can view it via the embedded player below or on YouTube:
I’m long overdue a multiple park run, so will start strategizing soon! The Parks On The Air program has also added a few new park in North Carolina, but none appear to be in the western part of the state.
Oh, and Phillip, thanks for prompting me to take the ‘817 to the field again. It is a gem of a rig and I think it might suit your needs very well!
One question that often faces newcomers to the hobby is: “Should I buy a QRP or a 100W transceiver as my first rig?”
That is a very deep topic, actually, and one to explore in a future post. A 100 watt transceiver will certainly give you more options as they can often pump out 100W or be turned down to 1 watt. If you’re a phone operator only, that’s got some serious appeal. Then again, if you’re operating POTA or SOTA where you are the DX, power–while still important–is much less so than, say, if you were at home trying to work DX.
Again, a deep topic for another post because there is no right or wrong answer.
One of our readers (Phillip) reached out to me a couple weeks ago and asked if the Yaesu FT-818 would make for a good first HF rig. He liked the portability factor, the build quality, the HF/VHF/UHF multi-mode coverage, and the overall flexibility of the rig as a field radio. His goal was to do POTA activations.
We had quite a few emails back and forth about the pros and cons and I decided it might make more sense to simply take my Yaesu FT-817ND (which is nearly identical to the FT-818) to the field and activate a park in both SSB and CW. Since I knew he wouldn’t necessarily have an external antenna tuner from day one, I paired the FT-817 with my resonant 40/20/10 meter end-fed antenna.
Lake James State Park (K-2739)
On January 17, 2021, I pulled into my favorite part of Lake James State park and quickly set up my station. I only had about one hour to complete my activation, so knew this would be a very brief excursion. Since I actually had a minimal amount of gear, it was a quick setup.
Since I deployed a resonant antenna, there was no tuning or matching involved which not only makes the most of your 5 watts (in that it’s more efficient), but also saves a bit of time in set up and tuning up.
I’m testing this prototype at the moment, but didn’t need to employ it at Lake James since it’s really useful when the rig is on your lap or on on the ground. It essentially gives you top-mounted controls and a larger display to read front panel information from above–incredibly useful for SOTA and proper in-the-field activations. Andy’s v3 board will include a memory keyer–I can’t wait for that one!
Since I had Internet access at this park, I used my Microsoft Surface Go logging tablet to spot myself to the POTA network. I started calling CQ on 40 meters phone (SSB) and within six minutes logged eight stations. Not bad for 5 watts and a wire!
Next, I moved to CW on 40 meters and started calling CQ POTA. The POTA spots page auto-spotted me via the Reverse Beacon Network in short order. In eight minutes, I worked six more stations.
I then moved to twenty meters which was essentially dead, so I called it quits a bit early. I needed to pack up and head to my next destination.
Here’s a QSOMap of this short activation (red polylines are SSB and green CW):
Truth is, each time I use the FT-817, I love it more. Sure it’s only 5 watts, has no ATU, has a small display, a clicky T/R relay, and questionable ergonomics, but it is a keeper for sure. Even after 20 years of being in production, it still holds its own and is an incredibly popular radio for good reason.
As I told Phillip, the 817/818 is the Toyota Corolla of the QRP radio world.
Andy’s article caused me (yes, I blame him) to wax nostalgic about the popular FT-817 transceiver. You see, I owned one of the first production models of the FT-817 in 2001 when I lived in the UK.
At the time, there was nothing like it on the market: a very portable and efficient HF, VHF, UHF, multi-mode general coverage QRP transceiver…all for $670 US.
In 2001? Yeah, Yaesu knocked it out of the ballpark!
In fact, they knocked it out of the ballpark so hard, the radio is still in production two decades later and in demand under the model FT-818.
I sold my FT-817 in 2008 to raise funds for the purchase of an Elecraft KX1, if memory serves. My reasoning? The one thing I disliked about my FT-817 was its tiny front-facing display. When combined with the embedded menus and lack of controls, it could get frustrating at home and in the field.
When I told Andy about my ‘817ND purchase, he asked if I’d like to help him test the FT-817 Buddy board versions. How could I refuse?
Andy sent me a prototype of his Version 2 Buddy board which arrived in late November. I had to source out a few bits (an Arduino board, Nokia display, and multi-conductor CAT cable). Andy kindly pre-populated all of the SMD components so I only needed to solder the Arduino board and configure/solder the cable. I did take a lot of care preparing and soldering the cable, making sure there was no unintentional short between the voltage and ground conductors.
Overall, I found the construction and programming pretty straight-forward. It helped that Andy did a remote session with me during the programming process (thanks, OM!). Andy is doing an amazing job with the documentation.
I do love how the board makes it easier to read the frequency and have direct access to important functions without digging through embedded menus. While there’s nothing stopping you from changing the program to suit you, Andy’s done a brilliant job with this since he’s an experienced FT-817 user.
The Nokia display is very well backlit, high contrast, and easy very to read.
“Resistance is futile”
I mentioned on Twitter that, with the backlight on, the FT-817 Buddy makes my ‘817ND look like it was recently assimilated by The Borg.
Don’t tell any Star Trek captains, but I’m good with that.
Andy has a rev3 board in the works and it sports something that will be a game-changer for me in the field: K1EL’s keyer chip!
