WGARS Spring Fling 2025

Today was the club’s semi-annual outing and this spring it was one of our old haunts, Cheaha State Park US-1037 in the fine state of Alabama. There are 3 things we as a club like to do, we like to eat, we like to socialize, and once in a while we talk on the radio.

As usual, food was in abundance.

We had several stations set up under the pavilion. QRM was held to a minimum. We had Xeigu G90’s, Tru-SDR, Icom IC-705, and my Yaesu FT-710. I set the radio up and turned it over to the club President John WD8LQT. John, like me is a CW op and I wanted his opinion of the FT-710. I didn’t have to twist his arm too hard. The setup was the radio feeding a Chameleon micro transformer with a 12’ whip and about a 20’ counterpoise. The radio was powered by a 20 amp-hour Bioenno battery and the paddles were a Begali Expedition.

Band conditions were poor and it took John most of the time at the park to get his 10 contacts. There were stops for eating and chatting. Early in the activation, I decided to change antennas to be sure we had an atmospheric issue and not an equipment one. I had my Diamond RHM-12 which recently proved itself to be a good performer. Once the switch was made and some searching through the bands, John started making contacts on 20 meters. I believe it was atmospherics and not the equipment. John got his 10 contacts and we called it good.

John’s comments about the FT-710 were quite favorable. Like any radio, there are pluses and minuses. In general he thought it was a very good radio for CW. There is more commentary from John on the YouTube video posted below. John did have one epic fail. The ear buds he was using which looked rather ancient finally gave up the ghost. I took it upon myself to intervene and unceremoniously threw them in the trash. John will thank me.

My review of the FT-710 is drawling to a close. I find that I like the radio. It performs well for its price point and has some features found on more expensive radios. It has its quirks as all radios do, but none that I find overly objectionable. I plan on keeping the radio and it has found a place among my field radios. I imagine the radio may make an appearance during this year’s Field Day.

FTDX10 or FT710

Yaesu came out with too fairly closely spec’d radios at different price points. The FTDX10 currently sells for ~$1,500 and if you add in the 300 Hz filter, another ~$175. The FT710 Field sells for ~$1,075. Roughly $500 less.

The FTDX10 is a hybrid radio with a down conversion receiver feeding into a Direct Digital Synthesizer (DDS). The FT710 is a SDR radio similar to the IC-7300. I owned an FTDX10 for about 18 months and I am on my second FT710, total ownership time is approximately 10 months. I had the first FT710 a couple of months after the initial release. It wasn’t working the way I expected it to so I traded. About 6 months ago, after reading some of the update material, I thought I would give it another go. My second FT710, this time the field version, is much improved. It is my current go to field radio. I plan on keeping this one. Having used both radios if I had to do it again which one would I pick?

I would pick the FT710. The FT710 has 90-95% of the performance of the FTDX10 for $500 less. In fact, I do not think one could tell the difference between the two in a side by side blind test. There is a caveat, the receiver architecture is different between the two radios and it requires a slightly different skill set. SDR radios like the FT710 basically run wide open all of the time. Keeping that in mind, in most cases it is better to run IPO or attenuation rather than preamp. I almost never run preamp on my FT710. What is nice about the FT710 is it gives you 3 levels of attenuation: 6dB, 12dB, and 18dB; a feature usually only found on higher end radios. In contrast, the IC-7300 only gives you one, 18dB.

The other control you should become familiar with is the RF gain. On a Yaesu, RF gain starts in the fully clockwise position. When there is a lot of noise, slowly turn the RF gain counter-clockwise until only the desired signal is heard. Coming from analog radios years ago, my brain is still a very good filter. I use digital noise reduction sparingly. I often keep it at level 2 or 3, enough to take the edge off.

Perhaps the most compelling reason to chose the FT710 over the FTDX10 besides the cost, is the ergonomics. I have large hands and fat fingers. The FTDX10 clustered its controls close together so I had to be careful when pushing a button or twisting a knob. Even so, I would bump the frequency dial and throw it off frequency. I have remarked that the controls on the FTDX10 were more suited for the lefthand. In fact when it was a part of my home station, it sat to the left side. With the FT710, the controls spaced further apart and are easy to get to even with my big mitts. This is a real benefit for a field radio. The position of the radio or the lighting conditions may not be optimal so ergonomics are important. I find the FT710 a joy to use in the field.

If you are a dyed-in-the-wool FTDX10 owner, this post is not for you. I wrote this for the amateur radio operator looking for their first HF radio, or maybe a seasoned operator looking to venture into the Yaesu family. This is also for those who have limited funds and are agonizing over which radio to get and should they sacrifice funds for the more expensive radio over something else they may need for the shack. The FTDX10 is a fine radio. Its Achilles’ Heel is its ergonomics. The FT710 is a fine radio in its own right. I believe it is 90-95% of what the FTDX10 is but for much less money. Of all the Yaesu radios I have owned over the past almost 30 years, the FT710 is the one I have been most happy with. YMMV de Scott

West Georgia Amateur Radio Society at Cheaha State Park

The West Georgia Amateur Radio Society (WGARS) is a great group. We like to do three things: 1) talk on the radio, 2) get together, and 3) eat. We did all three this past weekend during the Fall Support Support Your Parks on the Air weekend (POTA). We like to do about 4 gatherings a year namely Field Day, Winter Field Day, and the Spring and Fall Support Your Parks on the Air Weekends.

This fall we went a little uptown and rented one of the pavilions at Cheaha State Park (K-1037). This gave us shelter from the elements, power for the slow cookers, and plenty of benches to set up on. There were restrooms nearby with running water. Cheaha Mountain is the tallest point in Alabama and our pavilion was just a little down from the summit.

The weather was perfect. In the morning it was in the upper 40’s rising to the mid 70’s by afternoon. As I said earlier, we like to eat. There was an abundance of food, we had Chicken and Sausage Gumbo, BBQ, baked beans, buns, garlic bread, dunkin’ donuts, coffee, soda, and I am sure I missed a few. The bottom line is we could have fed half again as many and still had leftovers. There were over a dozen of us there.

We set up three radio stations. We had a Yaesu FT-991A and an Icom IC-7300. They were running FT8, CW, and SSB. I was running an Elecraft K3(s)/10 on FT8. My original plan was to run FT8 until it got warmer out and then switch to CW. However, we had a group gather around my station and we were doing what we like to do, kibitz and socialize. With FT8 I can run the radio and join in the conversation. We had a lot of fun chatting with one another. By the end of the day, I worked 40 states and 4 countries for a total of 120 contacts. The DX were Argentina, Canada, Ecuador, and Spain. States covered all 4 corners and in between. Not bad for 10 watts!

I had the pleasure of meeting Ward W4RE. Ward is a Vietnam Veteran and what made our meeting special is that we both served with the 101st Airborne Division. We were a generation apart with me serving between wars, but anyone who has served with the 101st understands that it is not a cakewalk; we had an immediate bond. Like me, Ward is a CW op albeit, much better than I. I am hoping that during one of our future meets, Ward and I can run a CW station together.

This was the trial run for my K3(s). I upgraded my K3 to a K3S. It is a QRP radio with a max power of 12 watts. The difference between 10 watts and 100 watts is about 1.7 S-units, a small change for CW. I operated the radio pretty much the whole time I was out there and it performed flawlessly.

While my K3 was in the shop for a repair and a going over, I put my name on the list for a KX2. There is about a 3-4 month wait for them and if things didn’t work out I could always cancel the order. When I received the invoice for the KX2, I asked my wife Mary K4SEZ about it, thinking it was worth a shot and as I was getting ready to cancel the order; she got on the computer and checked the books (she’s an accountant) and said “Happy Retirement”. I was ecstatic. I retire in 54 days and I have already made plans for that little radio. It was a great weekend that was full of surprises. Winter Field Day is right around the corner — can’t wait. 72 de Scott

Vertical Antenna Support

I like to tinker. Always have and probably, always will. This past weekend while I was activating K-2171, I swapped out antennas to see if one was any better than another. My first antenna was my Frankentenna set up as a vertical. Later in my activation, I switched to my random wire vertical. To use this antenna, I had to shoot a line up into a tree. Band conditions were not that good, and truth be told, I am not sure which antenna was better; however, for this activation, I gave a slight edge to the random wire.

For those that have operated within State Parks, rules and regulations sometimes seem to get a little blurry when it come to operating amateur radio within park boundaries. There is a general consensus that Park Rangers do not like things in their trees. I personally have not had this issue, but I was never approached by a ranger. I operate CW with earbuds on, so I do not really attract attention to myself.

Recognizing, that it might be a matter of time before I get “caught” with something up in a tree, I thought I would look for a solution to solve a potential problem. I have a B&M Black Widow 20′ fishing pole that should work just fine for my random wire antenna. A trip to TSC got me a 4 foot piece of 1 1/2″ x 1 1/2″ Aluminum Angle Stock. Tools used were:

Layout was pretty simple. The angle for the pointy end was 20 degrees and the slots for the straps were 3/8″ by 1 1/4″ (approx). The total length of the stake is 28″

I got everything cut out and deburred. I added a coat of zinc chromate primer and a finish coat of flat olive paint.

I have two small Velcro straps that I had lying around that work perfectly,

Then by turning the stake around, it stores nicely on the fishing pole. Together the outfit weighs a touch over 1 1/2 pounds. This is easy to carry and by moving the stake more to the center, it would be better balanced for walking.

This gives you options. You should be able to use this anywhere you can drive a tent stake into the ground. With this setup, you can use many different antennas besides a vertical. I am going to try it with my 40m OCF dipole (I may have to mount it a little down from the tip).

When I do an activation, I like to carry a minimum amount of gear. Sometimes, I feel my Frankentenna is too big even though it fits in a small Buddipole bag. It is fun trying to operate with a small amount of gear. For my next activation, I will bring the pole with everything else fitting in an 8 liter Bucket Boss bag. Instead of the Bucket Boss Bag, I could use a small backpack. In fact, I am thinking about doing a couple of SOTA activations this year. I hope to hear you out there! de Scott KK4Z
