Stan, My supply voltage is 12V, and I always use a 12V supply. The plot on 80m never comes to 2000 on the x axis, no matter how I play with the band configuration. After I disabled "20/80 BPF

Lun, the first plot you showed here, with values out to 2000 on the x-axis may work fine, and give you good audio, even though the plot is not smooth. I presume your supply voltage was around 9V?

Is there a straightforward way to delete a message? Any special characters one has to put at the end of a message to prevent this?

Replying to my own question here!? I don't think the Icom 705 microphone can be made to work as the PTT and microphone output are connected together.? My guess is when you press the PTT on the

Tom, Yes, pin 6 or 12 needs say 5-12 volts to power the Progrock's 3.3 volt regulator But the output of the 5351 pin 7 must not have an external voltage connected. If there is voltage a capacitor is

Hi Mehmet, I think the calibration procedure relies on both TX and RX. Is your RF/LPF scans look good on 20m? And transmitter voltage should be near 0V when not transmitting. -- 73, de BD8BTE op:

On 3/31/25 I had a CW practice / rag chew session on 20 meters. I worked one station: Date / Time Call Bnd Frequency Mode Power Rec Snt Name SPC# Off Comments 3/31/2025 13:27 NM1I 20

discovering more things on the rig. I finde, that the min. audio volume is still quite high but could not find a setting to alter that ( apart from muting it) -- Martin DK3UW

I had this also, just deleted and re-entered the message and that fixed it. Weird.

Hello, I bought a QDX used and never got around to using it. What is the best way to tell what voltage it requires and if it is high or low band? I believe it is 12v and low band, but not 100% sure.

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
