Hi Mark - so I tried the alsamixer and it shows the QDX as having a zero setting and I am unable to adjust it: Think you are right on the money here, just don't know what to do

I'm using 8 Ikea NiMH 2500 mAh batteries with mine. I just exceed the recommended 5W output on 30 metres when the batteries are fully charged, but I don't run data modes, so I'm not too worried about

I have been using a battery backup for Wi-Fi routers. Something similar to this - Mini UPS Battery Backup 37Wh Uninterruptible Power Supply for Router, Modem, Security Camera with Input 9V DC Output

For those that chose to go down the 9v pathway - I’m curious what energy source solutions you are using for field/POTA/SOTA type operations.

Very odd behaviour... How does it behave with earlier firmware installed on the radio? Ronan MM0IVR

Look into TN? 0110? (Microchip N channel mosfet)? type 92 plastic case? ?from? Mouser or? digikey.? Probably hard to find on ebay.? ?Check pinout - different. These have diff capacit.?

I've got AGC's fitted to all my QCX's, 3 minis and 2 classics. They're pretty much essential. As for the TCXO, my minis have them fitted although they've never really been used for WSPR where that

Need to try that !

In the case of QMX+ LPFs this could be even more unpleasant situation: 3.5 x 5 = 17.5 3.5 x 7 = 24.5 7.0 x 5 = 35.0 7.0 x 7 = 49.0 I hope this will be solved in due time. -- 73 Bojan S53DZ

Hi, there is for me a really annoying issue with the SWR and LPF scans.? It is connected with the DISABLE/ENABLE band settings and the SWR scans.? When all the bands are not enabled than the SWR

Hi Ludwig Attached is a file with the pix inserted.? The file names explain which each is.? I hope they're helpful. Regards Greg

There has been a lot of history of? ?disgusting people buying? 2n7000 and relabelling them as BS170.? The pin out is different. Most of such people live in? ?PRC others in Vietnam.... as

I have to admit that it is only a few dollars more. Who knows, maybe I will want to go digital. If anything it will make it more desirable if I have to liquidate my radios. The main reason for asking

I am seeing similar indications out of IC503 with my just completed QMX+. It was working fine for a couple of hours on 20m at 4.3w. Tried tuning up on 10m and power out went to 0w. Switched back to

See photo. This is a well build QDX 20-80 with 1.10 firmware.? Rev 5. It has been working flawlessly for just under a year. Receives on 20-80. Transmits on only 80m - See photo.? Radio thinks it's

Hi Bruce, Further to my last, you mentioned the very loud background noise on 40mx, which is so loud you leave the volume at minimum, to me that does not look normal. So, with that in mind there

Yes. AGC is worthwhile. The only issue I ever had with it was on Field Day when things were coming in rapid succession it might miss a first dit or two as the audio level is recovering from a really

Hans, thanks for posting this. I ran into this exact problem since I like to add a little "scope loop" to jumpers for future troubleshooting. My QMX+ is up and running! -- Randy, N4OPI

The agc is a must.

Thanks Ron. In addition to the question, can I assume that the AGC is worth putting in? -- Wayne S. KF7RCM
