Hi Ron, Way too much $$$ for something that is not working. Just saying!! Vernon

Hi Hans and all, Well after I sent off the note I put the 28mhz band on line along with all the others...so I had 28mhz first and then the rest in order to the lowest band...6 wspr tx on a 14 minute f

Hi Hans, Left a blank frame at the end of 5 bands with Park Mode set at #2 and frequency at 150.000.000 and so far all zeros on all bands. Will see how it plays out overnight and tomorrow. Many thanks

Hi all, Have been working on getting zero drift and frequency stability on one of my U3S units. So far... - Added a small heat sink on top of the 27 mhz xtal - Packed the area around the xtal between

Are most of the UK and EU 630m stations using the base frequency of 474.200 khz + the normal wspr offset. I have been listening the last few nights and have copied 19 unique stations but only 2 outsid

Thanks Hans...I redid the order of tx as you said and used park mode 2 @ 150 Mhz plus the small heat sink and all I see is zeros ( just like my bank account) LOL! So success as it also removed the sma

Thanks Hans...would I reduce the 150.000.000 maximum frequency by 28.200.000?

Hi all, I have been trying to reduce the drift on my wspr tx when running 5-6 bands. I seem to be able to get one band with zero drift and the next band in sequence has some drift. See the data for 20

your dial frequency does not fall in the RX window for wspr...7.040.150...you have to add 1500 or so hz to account for the wspr TX offset for receive.

Hi all, Will listen from about 1900z this evening to 1100z tomorrow am on 0.136.000khz dial frequency WSPR2 Using 500' elevated wire and Icom R75. Hope to hear someone. Vernon

Hi Chris... Are you on 136khz 24/7...I have rec'd many stations from EU and would like to see if I can copy you. Have 500' elevated wire that favors across the pond. Let me know when you will TX and w

Thank you…

I just noticed that when I press the right button on the U3S it does not key the transmit like 3.10a did…do I have something set wrong? Vernon

Well after connecting the control wires and then checking everything again to make sure all was what it was supposed to be I connected the U3S to a dummy load and hit the switch. Everything powered up

Hi all, I now have the V3.12 controller chip set up and working in my U3S. I have the 5 watt PA built with full assembly. My question is if I leave the PTT and the Cosine Shaping in a non-active state

Hi guys, Just to let you know that the reason there is no output is that I have the incorrect version firmware in my U3S. I was planning on building the simplified kit so didn't order the version 3.12

Hi all, I just completed the 5 watt amp kit and fired it up...glad to report no smoke but also no output. Turning the bias wide open did not do anything...I set the U3S at around 250mW before removing

Hi all, Have had this kit for some time sitting on the shelf so I thought I had better assemble it. I do have one question. I am only interested in the " Simple Assembly ". Will it run on version 3.09

Thanks Jan

Dave what is the exact TX freq. on 20M supposed to be?
