WSJT-X has moved on to 2.8.0 now.? The 'improved' versions are 'authorised' as they are made by one of the developers as a way to trial additional features, some of which are useful.? That one was

Thanks again Hans for the great work on this radio and firmware! in addition to many US and CA contacts from my QTH in Minnesota, I’ve made my first ever QRP DX contacts. Madeira island on the first

Ahhh, so thus 50v divided by 3 or 4.... Giving 12.5-16.6V. Got it. So it would be OK for 20v IF you had a perfect output load matched to the transistor? Makes sense. Thanks, Gary! -Nate N8BTR

Martin, It is a modified version, (improved in some ways?). Try it if you wish although I would think it best to use the 2.7.0 version if it does what you want. Hamlib is here

Richard, I did this in QDXs with a Wakefield heatsink I drilled and tapped. https://imgur.com/a/Nq4dUIN -Nate N8BTR

The RF voltage swing on the drain of the part is nominally twice the DC supply voltage but could go higher with higher load impedances. 3-4 times the DC voltage for the drain breakdown rating is a

I’m using this mic and can confirm the wire color mapping is the same as in the video. Same jack configuration as the (tr)uSDX which I have used too. The speaker is loud but emphasizes the high

I did an outdoor test of the portable setup today with the aim of going up a local hill later.? As I chased an Italian POTA and 2E0XGO/P on G/LD-036, Melbreak, without much effort on my part spending

Can someone explain this? I'm trying to understand maximum values of RF transistors...and the RD16HHF1 datasheets I see don't say 16v anywhere. I see 20v and 50v ratings...and I see things about rules

so that is not the original WSJTX ? If I am right my verson of WSJTX is 2.7.0 and I could not find, where to see the Hamlib version. I just wonder, if it would not be best tu uninstall what I have and

Hi Carol Thanks for this observation - I have just uploaded the latest SSB firmware, and done a hardware reset. I was wondering why the QMX+ RTC wasn't updating. Setting "software" mode cured it -

I just did a quick test at 12.0v using Transmit in the diagnostics, all bands are around 5w except 60m this was 6.4w. Just to emphasise this is just an observation as some people were have problems

My first SSB contact using the devices was over the internal mic, and using my left paddle to "key" PTT.?? It works, but was less than ideal. Currently I am using SSB over the USB audio and running

What is the highest frequency you are using the TN0110s on?

@Evan, thanks, I tested this as above, got 6.6k ohm gnd to Vcc and 2.3k ohm gnd to Vdd. @Stan I've ordered new SMPSU boards and I'll report back when I've tested as per your message Thanks to all

The current QMX SSB receiver can receive AM because what is transmitted is the two sidebands and a carrier but it's not receiving it as AM, it's receiving as SSB using one sideband of the AM signal

WSJT-X is frequently being updated and so is Hamlib.? The WSJT-X installation bundles a current version of Hamlib. I found that for a recent version of Hamlib the QRP Labs radios has been changed

That was just a really tiny part of their business but my HP48 calculator my dad gifted me in 1993 as I was studying engineering is still on my desk ! The keyboard can have small faults, nevertheless

Fascinating. ? ?Would be more so with : supply voltages that blew them power outputs that blew them where the BS170’s came from how they were mounted etc…

What is the power output during normal CW or digital transmit or Transmit in the diagnostics? AIUI the calibration has to be done over the full range of power output so I would expect it to be the
