The QRPer Board

Hi Tom, Welcome! I am not a trUSDX user, but I expect others can help. Also, try searching for trUSDX among prior posts. There may be something useful there. I do want to commend you for testing out your system before setting out for your first activation. When it works, it will give you confidence ...

Thanks Andrew, When I bought the AX1, I also bought an AE1 extension coil. When added to the coil for the AX1 and used with the longer 33 ft counterpoise wire, the AE1 permits tuning on the 30 and 40m bands. I have used the extension a few times. It will tune and make contacts, but requires more are...

Thank you Andrew! I had expected a stronger directional effect from the 2m whip, but your analysis lines up well with the QSO Map. The AX1 is not the best, but it is not a dummy load either. I guess even 5 watts of RF energy has to go somewhere.

Thanks Mike,

I was uncertain, but the AX1 continues to amaze me. A compromised antenna is, first and foremost an antenna.

Whip length of the VHF/UHF antenna is 32-3/16 inches or 82 cm.

Hi Andrew, Both antenna setups were identical, except for having the RV pull into the parking space beside my truck early in the second activation (a car towing a smaller travel trailer also pulled in on the other side, so i was truly boxed in). The mobile antenna is a dual band 2m/70cm whip. All op...

During a cross-country driving trip, we have been stopping to do Parks on the Air (POTA) activations at a number of state and national parks. At some locations it has seemed best to me to keep a very low profile, so that I do not distract others who are enjoying the area. For optimum stealth, I choo...

For those unaware, Thomas - K4SWL has been posting updates to QRPer.com from his home in western North Carolina, where overwhelming rainfall from Hurricane Helene produced devastating floods. His updates chronicle preparedness, survival, community cooperation for recovery, and the importance of amat...

When I first started my CW journey, I used decoder functions to help me improve me copy skills. It did not work for me, and quickly became a crutch that stopped my progress. When I let it go, improvement began immediately. My advice (4 years in): 1. Hunt POTA activators. You can get most of the info...

It has been a while since I have taken my Penntek TR-35 to a park. I had almost forgotten what a fun, no-nonsense rig it is. Paired with a linked EFRW, it was good for 27 contacts during an hour of operating in the woods. It was a great way to spend a cool morning!
