I don't have a 20m one. PeterO G0DZB

Hi Ted Wrong frequency. You entered the WSPR center frequency "USB dial frequency" from the WSPRnet homepage. This is the frequency you set on a USB receiver in order to get the WSPR 200Hz sub-band

Wow, thanks for all the replies, people! First, let me give my relevant settings from the config menu, then I'll go through the troubleshooting suggestions. "mode" setting: mode 0, relay 0, the freq

I ordered the 40 meter version right in the middle of the frenzy back on September 6th (Serial # they gave me is 934) and I got the notice yesterday that it had been shipped.? That's after they ran

Hi Cory It's not *that* bad... firstly, Karl's order wasn't placed 8th August (QCX wasn't even launched until the 21st); he ordered it on 28th August. Typo. Also... the density of orders was

Yes Cory, this is true, or at least it was for me; a kit number will be Emailed to you soon.? 73, Karl, KO8S

Hi Peter; This is quite interesting. I am waiting for my 20m QCX to be shipped. The question I have, does the 20m LPF experience the same or similar loss? Should the windings be -2 as you

I ordered a 40m QCX yesterday (Nov 7th 2017), so that means I should receive mine somewhere around Feb 6th 2018. I was emailed the order number ( #14,164 ) but I think there will be another email

OK Alan, when I'm feeling brave I'll try winding a new version of L4, with 19 turns instead of 16 and let you know how I get on. J

Now I'm getting approx. 50 mw out.? This is 6 volts PP at 50 ohms.?? Is Ray, If you are confident in your power measurement then try 30m. The 20m LPF should not significantly attenuate on

Quick question to the group.?? Finished building the Ultimate? 3s a week ago.?? Worked from the first power up.? I have the 20 meter band pass filter. Now I'm getting approx. 50 mw out.? This

Just launched my last flight for 2017.Had issues with wind during launch and had to modify some weight issues but in the air. Jim,N2NXZ http://www.qrp-labs.com/flights/u3s19.html (

Hi Hans, Thanks for that and info. That is exactly how I removed turns from my LPF, I just resoldered the lead to the top pad instead of trying to get it back in the hole, a lot less headache. Joel

Use a round wooden toothpick and put it through the molten solder, reheat and jam it through. Bamboo toothpicks work great. 73 Larry KB3CUF

I hope that's not too long. You could test the RX on Dial 5.364700 (TX 5.366200+/-) as used in EU. Conditions not been too good X-pond the last few days but usually signals make it OK. 73 Alan

Hi all Just a quick observation. It is indeed VERY difficult to replace components, or to take turns off toroids and get the wire back into the hole when it is filled with solder. Here I do have

Just an update on my 60 metre QCX.? So, I did have to remove 5 turns from T1 to be able to peak the C1 trimmer. Luckily, I have a solder sucker, because trying to poke a 30 AWG wire through a

Chris, Possible but not really necessary. A LPF does not peak, it is not really too critical. I'm not sure I've ever seen an adjustable LPF. I guess if the inductors are too high then the amount of

Hello Peter, I have never built one of these, but is it feasible to build an external LPF with beehive trimmers instead of the fixed caps to bring one spot on? Wednesday, November 8, 2017 -- Best
