Hello, Disclaimer: I am not a qualified engineer or professional programmer. I was looking at the schematics of the QDX and was thinking of this idea, of adding a Bluetooth. I think hooking up a

The problem is that those links require an end user to look for them. They don't, they go straight to what wsprnet shows in the top left and corner and then get confused. The website really needs to

Both Minis and the QDX have been sold. Thank you and enjoy. Phil, K3UT

Sorry, scratch that response Robert, I didn't read the, "in Europe" part. Glory to God in the highest, and on earth peace, good will toward men. Luke 2:14

I have had several discussions with users who want to TX at the higher end of the band and with these typical descriptions, they go "above it". They hear 1500 Hz off set and 200 Hz receive band and

Hey Robert, I'd keep an eye on this one.? The last one he had sold for $40 because no one bit on it and the purchaser gave him stellar feedback so I guess he liked it.

Sorry, T2 primary obviously. My mistake. I can see that Hans quite did the job with BPFs, quite...? ?I saw that I still have to adjust L12 for 30m BPF.? But after I change the IC3.? Hot air

On the QDX rev 3a PCB board, capacitor C41 is completely shorted to GND, because of a PCB board fault. The latest assembly manual (rev 1.12) shows on page 13 how to fix this. My question: How will the

Hi Geoff, Yes, as I measured that resistance between pin 10 to 13, I removed C30. I left unassembled the 80m LPF, so I just bypassed it and band config it to all bands during measurement of BPFs.? I

I ? bought one like this and found it useful but then I came upon this one from All Electronics, more costly but seems to work better….

Those are beautiful I. Their simplicity and size, assuming the paddle on the right is the size of a nickel (?). I'd be interested 72, Ted k3RTA

How did you measure the bandpass filter and low pass filters separately ? Remove diodes D1-6 to get access to LPF but receive is a bit more difficult. When I did a simulation with Elsie, I found that

Jon I do not know, set the polling to 99 seconds in WSJT-X, might reduce the number. Can't think why Hamlib wants a driver. This is the latest general release of WSJT-X?? I think ideally the QDX needs

Hi Marc, I would hold off on installing the BS170s.? You can test the receive function without them; their failure can cause more severe problems during testing if the rig goes into transmit. Have

Hi Ed, I had same problem with my QCX Mini 20 meter. The number of spots I was getting was very low and all showed a drift of 4 Hz. I think anything greater than 4 Hz results in a no receive. I tried

Hi All... Am enjoying my recently built QDX, awesome little rig! Have been playing around with a few things, and in looking around,? noticed a couple of error message like things in the WSJT-X

I simply found for my 80m qcx plus it had way too much audio. So I added resistance to decrease its audio gain. It works, I can still copy weak signals. If I had to have agc in a plus I would homebrew

John, just thought but have you tried a different PSU to your QDX. I did have a few issues at start up on my QDX when I had the current limit too low on mine. 73 Ken g4apb

OK John, fight down the panic, think logically, gets you there:-) 73 Alan
