Regarding LiFePo4 batteries, typically 4 cells in series is better than 3.? With only 3 cells, it will be just under 11V folly charged and will go down to 9V when mostly dead. 3S is better for LiPo

If you’re on a budget like me, any 12 V batteries gonna work great. I mean come on, these things don’t draw very much. HI Trevor/ N0YMA

For just a single band and using WSPR.. Set the frequency up in the first slot, but remember that you do NOT use dial frequencies. For a U3S you specify a direct frequency to use within the WSPR

Hans I've only just put v1_06_005 on one of my V1 QDXs. On 5.364700 it transmits almost exactly on 5.366282 as expected. (Needs a few Hz tweak on the calibration.) Further tests to follow.. 73 Alan

I’m wondering about a copper crush washer under the flat washer provided? That would conform to the BS170 and provide better thermal transfer. Brad

Hello Cliff Very strange... please could you let me know, exactly what USB Dial frequency, and what audio offset frequency, you are using? And is it WSJT-X for example by pressing the "Tune" button,

Yes, everything is best described in the Operating Manual from QrpLabs. To my view. 73 Bojan S53DZ

Dean, Not that I know of. Most of it is in the Operating Manual, use Ctrl-F search for all instances of WSPR so you miss nothing. Then ask if in doubt about anything. (Or search previous posts,

--REV 4 does have a Q7 but it's been upgraded to an AO403. Your symptoms are identical to mine on REV 3 which was current limiting at 1500mA. Check the power socket hasn't shorted then check Q7. I

Cliff, The rev 4 does have a polarity protection Q7.? It is a different part (AOD403) with a much higher power capability.? Still worth checking, though not as likely to fail as the Rev3

Has anyone put together a quick start guide for getting the Untimate3s up and running on WSPR -- Dean -- This email has been checked for viruses by Avast antivirus software. www.avast.com --

BTW, the measurement at secondary #2 was not nearly as nice. The peak at secondary #2 was not in the same place as the peak on secondary #1. So I adjusted C1 to move the peak on secondary #2 to the CW

OK, reporting back as requested. Here are the results for the band pass filter. Sorry it has taken so long but life is pretty hectic (won't bore you with the details). The Mini is configured for

Thanks Hans, the LED flashing (I have now re-read that part of the manual) - tells a lot. All working now on all 4 bands.
