To all who are asking about being part of a new group buy of the ABS add-on for the QMX+: Cal and I have you on our list for a potential new group buy of the ABS boards and components.  Sorry for the

Okay Paul. Thanks. Just my interpretation of the schematic. I will take that under advisement when I check it again . gmail.com@groups.io> wrote:

If Q508 is turned on by the gate voltage, I'd expect 0 volts on the drain. This FET is really operating as a switch... Source connects to DC ground through L503 and to the receiver input, signal from

Please see this thread from a couple of weeks ago, a user with the same question: https://groups.io/g/QRPLabs/message/135417

So I had some more time this evening to do some quick checks. First off, it requires a look at transmit and receive schematics to get a good grasp of the receive path but since I have continuity

Hi If possible I would also like to sign up to a group buy if available Thanks de stephen zl1any

Hi Mike, I'm expecting my assembled QMX very soon. I received an iPad mini 6th generation as gift. It has OS version 17.4.1. What cabling will I need to connect them together to operate iFTx? I'm

Good luck in finding the failed part - the ICs are more likely than any of the other parts, and there are only a few of them on Vcc, so it shouldn't take too long. And if you go with the linear power

Spurious regulations are tougher in this spectrum because it's used for public safety. Perhaps a tiny SA may not be good enough. So filters might have to be factory aligned. Perhaps better to assemble

What was happening is that I had split "fake" enabled and the Region 2 band limits.  When the rig split on 60M it was outside the channel and TX shut as it does for high SWR.  I changed the band

Derek, I may be confused but I am unable to find any document(s) or other file(s) attached.

Good evening! Big thank you to Hans and everyone else in this forum! I had a lot of fun building these kits and I couldn’t have successfully completed them without the folks who ask and answer

I want to thank the ones who contributed to this document from here on groups.io/g/QRPLabs or QRP Labs QMX enthusiasts ( https://www.facebook.com/groups/1026574931765550/ ). Whether be formating,

No this is not normal.  It gets only warm during normal operations, including transmit. Note: it is dangerous to operate the QMX without D108, especially if there is a short on the output of the 5V

Everything is working perfectly now, thanks for all the help. -- Trevor (N0YMA)

Thanks John, that was it! 73, Bill NZ0T

Bill, This could be the 'out of band' indication - see p10 of the Operating Manual 1-00-026. 73 John M0JBA gmail.com@groups.io> wrote:
