I needed another rig like I needed a hole in the head, but I couldn’t resist. I’ve had my eye on the Penntek TR-35 for a while now, so I finally pulled the trigger and ordered one. I considered it a Father’s Day present to myself. Two days later, I had the TR-35 in my hands.
Lacking the patience and the close-up vision for serious kit building these days, I ordered a factory-built radio with the rotary encoder tuning option. Now, I have seen plenty of pictures and videos of the TR-35, but the small size of this rig really struck me when I opened the box. Its footprint is not much larger than a QSL card. It’s a perfect size for portable operating.
Here are some features that drew me to the TR-35:
- It covers the bands I use most in the field (40/30/20/17)
- Built-in iambic mode B keyer (my mode of choice)
- Two CW memories. Perfect for POTA activations, QRP contests, etc.
- Separate inputs for paddle and straight key. I sometimes get calls from fellow SKCC members, so it’s convenient to switch instantly to a straight key for those QSOs.
- No complicated menu structures to navigate to get things set up. The TR-35 is super-simple to operate, and that’s just how I like it.
The TR-35 doesn’t include a built-in tuner. No worries; I’m going to dust off my little Elecraft T1 ATU and show it some love. An SWR indicator would have been a nice feature to have, but I can get along fine without it.
Taking It For a Spin
I didn’t have a chance to put my new TR-35 on the air until today. I drove over to Valley Forge National Historical Park (K-0761 and KFF-0761) to try the new rig on a POTA activation. Doing an activation with a radio you’ve never used is a little like going camping with a tent you’ve never set up before. But, what the heck, I was a risk-taker today. Actually, I brought a backup rig along, but I never needed it.
I set up the TR-35 in the cab of my truck, along with my T1 tuner. The antenna was my homebrew 19-foot vertical on the back of the truck. As soon as I powered up, I was greeted by lots of loud CW signals. That’s a good sign. I quickly programmed a “CQ POTA” message into one of the two CW memories and got on the air.
One of the first things I noticed is how loud the audio is. I was using earbuds, and I had to turn the volume almost all the way down. The sidetone seemed a bit loud for my liking, but not really much of a problem for me.
Once I got going, I had a lot of fun with this little rig. I easily made contacts on each of the four bands (40/30/20/17). The TR-35 is a joy to operate, and I really appreciate its simplicity. Tuning with the optional rotary encoder is smooth as silk.
After about an hour and a half, I had 24 contacts in the log, with five park-to-park QSOs. My stomach reminded me it was lunchtime, so I packed up and headed home. I left the park feeling very happy about my recent purchase. The TR-35 is going to see a lot of use in the field.
Happy Father’s Day to all the dads out there.
