Hi Vince, I set mine up as follows; *U3S v3.12a:-* Slots 0-3 RX mode (= 4 x 2 minutes = 8 minutes of Rx time) Set freq to USB RX freq (dial) CAL 10 115 (takes 2 minutes plus display of cal) FRAME 10

Tim Looks like you've read the troubleshooting. Have you checked LCD voltages and very carefully checked the solder joints? Not too much to go wrong between the LCD and processor. 73 Alan G4ZFQ

Vince, No, park mode is the RX setting. None. WSPR is not controlling TX. Set for RX only. 73 Alan G4ZFQ

Andy, I've never checked like that, not sure about IC6 but if you get hum before that then presumably it's OK. You have grounded the RX mute? Have you checked voltages on T3, C3-6 Q2? Might give a

I'm currently using a ~40 foot vertical end-fed wire held up by a 12 meter Spiderbeam fiberglass telescopic pole (

Hi Peter, It looks like the Arduino Shield manual needs some updating! If you haven’t already figured it out... Jumper W4 & (W5 unmarked on silkscreen) connect Si5351A CLK2 to Arduino pin 1. Jumper

Just finished building one of my kits, decided on 40M as first one. This is one of the original 500 kits, yea I know I am slow, down time this weekend due to hurricane so went at it full bore. I have

Hi All? first time posting, just built my 20m QCX? and at first please it seemed to be working ok, about 2.5 watts at 13v which is ok for me but my problem... i can not find a peek on the front end

Hellschreiber coming in nicely 2256 miles all the way from SW Washington state to Florida using 500 mW. ?I'm transmitting “AA7US CN76XH AA7US CN76XH” on a 10 minute frame.

Good evening, I am trying to set up my U3S with the receive module and have 2 questions I could use guidance with. 1.? I have set up Park Freq and Mode params as per manual.? Do I also need to set

Glad you got there. Have fun ! 73 de Andy

Thank you Andy! Using slow Hellschreiber mode with the speed you recommended did the trick. ?It looks great. Yes... despite the reduced signal strength, a little beaconing variety is what I'm looking

Don't use lead free Euro-solder. That generally solves most soldering issues!

Following on, I have a hiss from headphones attached to output jack fed through the polyphase network board. I am able to alter the volume of this hiss. If I touch input pins of IC3, 4 and pin 5 of
