Chris, With respect this sort of thing is good for black box users. But my feeling is that generating "vast" amounts of power then wasting it in an attenuator is not really true QRP. I think

Hi, can confirm this problem. My right encoder goes forward and backwards when turned slowly. The leftone is working precisely. Vy 73, Peter DL4PJ

Links to SotaBeams switched attenuator (switched in by relay on transmit/switched out when not transmitting, on

QMX observations FW 1_00_017 QMX covers the 80m-20m band, but I don't use the 80m band, so I chose it for the 40m-15m band. 1.Setting japanese limits to ENABLED. When transmitting at 17m and 15m BAND

I touched up the solder joints on all the LPF capacitors and toroids, and also adjusted the turns spacings on L401 to match more closely the photo in the assembly manual.? Reconnected the radio to

I agree that it is unlikely that Hans will want to find time for incorporate a reflectometer into the QDX with associated extra software in the controller.? Part of the problem is that, unlike the

Yes, that one had me questioning my sanity when I first connected the straight key. Ring is tip and tip is ring! :) 73, -Lloyd Sent: Saturday, February 24, 2024 9:13 PM To:

Kjell, When I'm in a mood for QRPp, I haul out my Zachtek "Flea" transmitter and the ATS-25 general coverage receiver I use with it. It's only 300mw, on 20, 30, and 40m. It doesn't have to be that

Rather than try to add SWR protection circuitry, try protecting the BS170's: https://la3za.blogspot.com/2023/04/3-tips-for-not-blowing-finals-of-qdx.html I also added the zener across L14 for good

I am a nubie to the group so be easy. where do i find instructions for the above unit? dave k7da

Ludwig, Am I understanding that you were finding T37-17s to measure 25%+ high when you wound them? And your further work with T37-10s is validating your measurements? I'm working on a QDX HB, with

I once set up a BIOS EPROM to flash SOS on the carry light.? Well actually any message in Morse. Chris, G5CTH

Hans, I know upgrade is easy, I've done that before ;) Believe it or not, my (yes, MY) problem is, that PC I use on daily basis is unable to write USB drives. Can read but cannot write. Unbelievable?

It was a standard routine done back in the Vaudeville days performed by many acts. The 3 Stooges and Abbott and Costello both have famously recorded versions. A true classic!

No... don't worry, it will all come good in a few days! 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl

Should I be worried if order 82084 shipped but 81846 is still just showing as "Complete"? I just want to make sure that mine hasn't slipped through the cracks or something, since I never got any

I'm not clear on what Simon is saying.? In my case, I have the clicks all the time, but they are much worse if there are are other signals in the receive passband. 73, Randy, KS4L

When using Win 10 and 11 I see? receive gain is easily adjustable, usually 50db range with my FT991A? utilized on Digital modes However with QMX and W10 &W11 computers on WSJT-x best I get is 30db
