QDX on FST4W


Chris Mackerell
 

I reckon that -41 is a glitch for some reason. Doesn't seem
reasonable compared to what else I'm decoding.

Happy to keep on spotting from the Down South ūüėĀ

Cheers, Chris

Hi Chris,

In addition to spotting Paul, you spotted Glenn N6GN at -41 SNR.  I didn't think FST4W-120 decoded at that low a SNR!  Thanks for operating our one Southern Hemisphere WD station.

Yep - I noted a couple of FST4W-120 here in ZL-land recently.

I have just put my modified QDX on 20-meters, running FST4W (-120 for now).  I installed a little reference-clock multiplier (takes 5 or 10 MHz in, delivers 25 MHz to the QDX), and the transmit frequency is rock-solid.  I posted details to my blog: STABILIZING THE QDX
Apparently it's working well, even with my crappy antenna: a 30-meter dipole, one leg horizontal, the other vertical, with an MFJ manual Pi-network antenna tuner bringing the SWR to a reasonable level.
