Leaving the 20/80 BPF TXswap disabled,? I messed around with the band edges and center frequencies for 20m and ended up with this. It doesnt resemble any of the examples I've seen: Is this good,

I have programmed my first message into the qmx+, but when I play it back on the air, it appends lots of extra characters at the end. The characters do not appear in the message memory when you view

I just noticed a funny thing . My Logging software indicates the QRG? and when in A&B it indicates VFO B and not the receiving VFO A. On transmit it then changes to the QRG of VFO A but transmits on

Hi My reader is very erratic with a lot of *. can someone who has a good setting let me know how they are please -- Martin DK3UW

Thanks, Hans, I think they call those "AI hallucinations"! Randy K7RAN

Two comments here: - Yes, the ProgRock2 (nor the original) have coupling capacitors on their outputs.? If you aren't sure if you need one, *add one!* Don't go overboard with the capacitance -

Hi Ludwig I have ordered the correct Mosfets should arrive tomorrow, I will measure the LIN_REG_EN and then solder the mosfets, just to confirm the LIN_REG_EN should be 12V when the button is pressed

Or actually not! It looks as if the transistor had been in place and fallen off. When this did happen cannot be said. It even would have been possible to pass a function test. I’m happy that it was

Hi Lun, Thanks for the tip. Sadly, it didn't work for me. Mel, M0KMD.

I didn't add one. How does it work without some DC going to pad 6 of the unit? It seems the unit would need the pad 6 to be connected to a voltage source. Tom

Same Issue with mine.? QMX Rev 4, firmware 1.00.027.? No PWR nor SWR showing up. f/w issue? thx JD

Yes. The stripe is on the pin 1 end of the device. Tony AD0VC ________________________________ Sent: Wednesday, April 2, 2025 8:17 AM To: [email protected] <[email protected]> Subject: Re: [QRPLabs]

Reminds me that an automated comparison of board images taken after assembly should be able to catch this sort of fault before it gets shipped thousands of miles around the world. You can even see

I don't believe this is actually implemented in code yet. I wanted to do something similar a few days ago. Julian, kf4mot

This is probably a stupid question with an obvious answer, but I don't want to screw it up.... Received replacement parts from Digikey. Removed old IC503 without incident (first time using

Tom, I think I'm right in saying there are no isolation capacitors on the Progrock's outputs. I hope you added one. Any voltage on the equipment's crystal socket could damage the 5351. 73 Alan

Hi Alan, Well, I thought I had the ProgRock2 programmed for the 6.6khz frequency, installed it with the two pins of a HC6 crystal base with a backside ground terminal soldered to the holder base. I

Hi All.? I have a similar goal-? screen is way too bright.? It does not seem to be the issue of pin 3 hitting the inductor on the power board.? So with r306, there are two solder pads on either

I reached out to Jeff through the web interface for this group. He found a few issues with my mid band QMX, a couple of shorts (one of which took out my smps and cpu) and a few other minor issues (we

Hi, I've just finished my QMX+ rev.3 (firmware 1_00_027). Everything seems to be working correctly, except for the SWR and PWR does not show. They don't appear on the LCD, even though I have them
