Thanks Hans. Mystery solved.

Hi Andy, John There was a request to keep the output on frequency and the TX going, in FSK/CW mode in between frames, except during the 13 seconds calibration, so that the temperature would be more

Hi Don WSPR works fine without GPS. You won't get more spots with GPS or without it. GPS will calibrate your transmission frequency, and it also will keep your realtime clock accurate. Without GPS,

Aha - did that feature get dropped in order to meet the GPS calibration procedures ? 73 de Andy

Hmmm, I'd normally expect a decent bench PSU not to create the problem you've described. But at unless there's a problem with the PA stage then it does usually point to the PSU. You'll need about

Hi andy thanks for the reply. PSU at the moment is a bench supply. When the kit is boxed up it will have its own 5v supply. As you said on your last reply it is the DDS carrier that i'm seeing

Sounds like the PSU is the problem. Are you using something simple like a 5v regulator to power it ? If so attached a voltmeter scross it under no load and then observe the voltage whilst putting

Hi John, When you say does not stop tx'ing I presume you are lstening on a nearby RX. If so then what you are probably hearing is the bare DDS output breaking through at a low level which I think is

Hans, Yes, big variance in price from China. I saw one at 61 cents! I bought 2 @ $2.59 ea. from NY. I hope it works! What do you think? No GPS and WSPR works fine. So says Paul. But, what I have

Hi Don That made me chuckle! A month or two ago I bought an AVR programmer (USB) from NoElec for $7.50. It arrived perfectly etc no problem. Later I found exactly the same one is available direct

Paul "The GPS is not needed" Good to know about WSPR can work without GPS. What's a good number to start with to nudge the 20 MHz oscillator? Anyway a new GPS should arrive in a couple of days, but

It could be that the chip is not seated properly. Push it firmly into its socket and then try again. John ? Digitally signed mail - M0ELS ________________________________ To:

Morning Chaps - Ive an oddity and need to spend more time on it but I built the unit and it works fine with the GPS off. I cant get the NMEA and GPS to function at the moment (but that may be resolved

Frame = 10 start = 0 All gnd's are common PSU Set at 4.9v TX 14.097100 Output 9VPP After tx cycle output drops to 2vpp. If I go into menu between tx cycle then output drops to 0. Same on all

Ovious question is if there is any RF floating around? and then if all grounds are grounded to common ground. I have frame =10 and start = 0 for WSPR mode. You could try this and if that fails, then

Received my QRSS kit2 today. Built it and started testing on wspr. everything runs ok, except that after the 2 minute tx period in wspr the display switchs back to the clock and displays the next tx

I am still having an issue in that when my HF rig is on and connected to the receive port, the output in? transverter TX mode drops. A s soon as I switch the rig off, it comes up to normal level. I

I managed to get it running, by deleting the message contents Hans. Now got it running with my transverter and output was originally not enough to drive the transverter, until i switch my hf rig

Hi John To be clear: I think you have put in your callsign, locator and power into the Message setting. This is not what is needed for WSPR! You need: 1) "Mode" set to "WSPR" 2) Your callsign in

Hi John In that case, you have to put your callsign "M0ELS" into the "Callsign" setting, and it will be used for WSPR. 73 Hans G0UPL
