Pardon me if this has been asked before. Regarding the "20/80m BPF TXswap". Am I correct in assuming that this is in reality is a BPF 1 and BPF 3 swap without regard to which band or slot in the band

It sounds like the Terminator movie :)

Hi I found them from a supplier in Turkey search for "precision IC socket" https://www.direnc.net/6-li-precision-soket 73 de muhsin TA1MHS

There isn't any way to maintain the current real time clock when powered down as it is run in the main processor code. Not the low current RTC peripheral. There would be potential ways to do a partial

Luc you rased the question on the rules for the challenge as you used a Bingo on 80 m. To my understanding the challenge gives points to an operator using a QRP Labs rig . Any non QRP Labs rig should

That pretty much closes the case :/ thanks, @Hans anyway. BTW is there a way to make it keep the time when powered off but with power supply kept attached?

busy 13:00 session on a good 20 m band but no luck with the US QCXes. Some QMX also around and? OH8TX with a QMX a new one for me 19:00 difficult QSO with PA0CMU on 40. Very poor condx and the band

Installation of a lightning arrestor which is attached to a ground system at the shack end of the feedline will help divert common mode currents and noise (and hopefully, lightning energy) to

What is a name or part number for the sockets? I've not seen them before, but like the idea. Thanks, Don KD5NRO

Lynx, Jeff Moore W1NC repairs QRP-Labs radios for others.? He is recognized as one of the best repair people in the group.? He ran into a weird problem on a QMX related to the frequency that

Hi Just an idea /g/QRPLabs/message/116758 73 muhsin TA1MHS

Thankyou Evan for putting me onto the right track. So below is the picture of the windings as I made them originally. (I saw a picture of them a bit like that in the manual? page 37, so made them

Hello, The lockup occurs wether the QMX is in practice mode or not (happened to me twice last week while in QSO-s). I believe the issue was reported before, along with other CW keyer glitches.

Excellent article. I have a choke balun that I wound at the base of my vertical but I need to do some work on my radials. I also plan to add a choke at the xcvr. end of the coax. Thanks Mike WA8UOC

Mine failed in my Rev 5 QDX, but not as toasty as yours! I had mine into a speaker wire dipole on 20m. Dipole is in my attic, so no exposure to wind, rain, etc. SWR was <1.6:1. I added a diode across

Peter, You obviously do not read this group:-) Many of the posts are about BS170 failure, what else may go with them and ways of stop it happening. I fancy that it is not actually as common as one

This QMX is running the latest firmware 14. Rig receives and xmts. fine for the most part. If I place the xcvr. in practice mode and begin sending code, it will ocasionally lock up with continuous

A quarter wave vertical antenna needs a path for its return current. The high current point for a vertical is at the base of the vertical. The return current path requires a similar high current.
