Evan, Many thanks for your suggestions. ?Here’s what I’ve found: With 20m selected, the cathode voltages for both D3 and D6 are 4.8V, rather than zero volts, so there’s something very odd here.

It is a pretty simple example of AGC, but the board is inexpensive and your ears will be a lot happier for having it. It's a breeze to install too, with the latest QCX+ revisions anyhow. No intricate

This is by far the best way. Receive WSPR, get to know it. Remove the RX antenna then it will monitor your own transmission, you can see what happens. Exact frequency, timing, drift all easily

WSPRNET shows in about 30-45 seconds as it takes time from a station hearing you, his Internet’s lag time and so down the line. Some spots come in .longer. I have been following this thread and

Thanks, but it will not take [blank]WA7EM. It will take WA7EM{blank} and it will take WA7EMM. I discovered the oscillator calibration steps 8.11 and 8.12. I did them and seemed to work as documented.

I bought a used QCX some time back.. .and after a bit did the most recent mods to date for it. At the beginning of the Pandemic I bought an unbuilt kit and again built is to the mods as of the date..

I just made the prototype for my V2 key. :) I am waiting on magnets and will have a few for sale the beginning of September. -- Colin Kaminski - K6JTH https://www.qsl.net/k6jth/

The QCX minis have been sold. QDX V3 still available.

Sorry Byron. My mistake I misread your call. Anyway Hans did a good job in explaining call sign entry. Probably it is freq. related. The GPS should calibrate the QCX. But it takes one frame. After the

I bought one of those last year, for $18 on eBay. I didn't have high hopes for something built so cheaply, but it's proven to be remarkably useful! Basically, just connect any part and it tells you

On the call sign entry: The issue is that the call sign digit must be in the 3rd position. This is required by the WSPR encoding algorithm. Since you have a two character prefix, you do not want a

Can you hook your FTDX10 to a computer running wsjtx and decode the WSPR transmission? 73, Willie N1JBJ

I forgot to add make sure GPS disconnected in menu mode. The incoming data is confused by GPS and? the program gets balky.

Set to 14097.140 . When you see call you must leave a blank at beginning and end. At call sign entry rotate dial and go to second blank and start there. After last letter leave a blank by rotating the

The mini is such an amazing product. Truly brilliant. An amazing blend of circuit, software, packaging and manual. Well done. -- Colin Kaminski - K6JTH https://www.qsl.net/k6jth/

Thank you Hans! I'm glad it was successful so I could have the chance to own and operate this beautifully designed transceiver. -- 73, Dan - W2DLC

I have connected a QRPlabs GPS to my QCX mini. The GPS finds satellites and sets time on the mini. I do the setup steps to put the mini in WSPR mode. It comes to life at the specified time and

Evan, I tested the BS170, i have 2.5 on all gates with all bands on transmit. ?I did the audio sweep test, it looks like the example one on the product page.

Thank you, Hans, for all the joy you are spreading in the ham radio community! I love the picture- sure shows how far the QCX has come… Thanks - 73 Mark N5YYY -- | R. Mark Adams, Ph.D. |

Hans, such a great product and contribution to the ham radio community. Many thanks and congratulations to you and all of your staff. You guys really deserve it.Gary W0CKI
