Hi Andy, If it is any help, I have managed to used 0.5mm Enamelled Copper Wire on an LPF, it was a tight fit but not too tight once the Enamelling was cleared off. 73, Colin M0XSD. Sent: Tuesday,

Hi Andy The wire is specified as 28AWG (0.37mm). According to the PCB layout program, the specified drill size for the toroid holes is 0.6mm but I suppose some thickness is required also for the

Can anyone confirm what the wire guage is as used on the LPF's please ? I make it either 28 or 30 SWG. I've stuffed up a few toroids and run out of wire, so I need to be sure of the guage,

I'm amazed how much I am smiling after getting the U2 put together, and screwing it into the 160M loop that drapes around the back yard. Seeing 4 others hearing me on WSPR is a real

Hello Hans Oh dear, how red can a face get, they are of course BS170s! Even worse, I do now recall reading the explanation of the code when I built the kit. Also, I had the frequency set to

Hi Chris The 3 digits are the last 3 digits of the frequency (right hand side, or least significant). E.g. if you set your frequency to 10,140,100 then in the WSPR mode the three digits will show as

Returning to amateur radio after a break of about 30 years, I'm having a blast with WSPR, initially with an Ensemble RXTX and, in the last week, with my newly built U2 QRSS. It's been running fine on

Hi Andy Luckily, I have 680pF caps! They are used in the 40m kit. So I will put together some kits for a 60m LPF and add them to the range! Thanks! 73 Hans G0UPL andyfoad@...> wrote:

Hi Eddie John was asking about QRSS and CW. The issue you're referring to is the one where the DDS output in v2.01 is very briefly set to 0 before being set to its new frequency. But that is only an

Just been playing here with a design for the 60m band which may be of use to U2'ers, or Hans if he's requiring a 60m LPF design. Take one of the 80m LPF's. L1 = 23 TURNS (WAS 25) L2 = 24 TURNS (WAS

Sorry to disagree with the designer Hans, but I would say that the upgrade is essential for all U2's. U2's on QRSS can be identified on air by the LF and HF spikes which are still clearly visible at

Thank you Hans.... I wish everyone supported their products as well as you do! 73 John K5MO

Hi John The upgrade is mainly useful for people wanting to use GPS, because v2.01 is evidently much too fussy about GPS modules it supports. It is also useful for people wanting accurate frequency

Would the upgrade be useful to anyone planning on deploying their kits as either a QRSS beacon sans GPS or CW beacon? 73 John

How about offering people a free upgrade with their next order? 73, Colin M0XSD. Sent: Sunday, June 2, 2013 1:39 PM To: QRPLabs@... Subject: Re: [QRPLabs] v2.02 firmware version coming

Hi David They way I was thinking it would work is, there would be two ways to get the v2.02 upgrade: 1) I'll put the v2.02 upgrade in the online shop as I used to do for the "Ultimate" (a.k.a. U1)

Hans, and the Group, I was going to stay out of the 'Me too' postings, even though I am just as excited by the prospect of putting my U2 to some serious beaconing as any one else. But I wasn't part of

Hi Hans, That's what I initially reported but this new observation is different to what I said before. It's simply not calibrating at all. I can switch on at [say] 09:01 with a frame time of 10 and

Hi Keith What I found in my testing was that if the calibration takes place before the FSKCW starts, it is successful. But once the FSKCW has started, the GPS frequency calibration doesn't happen,

Now I appreciate that there's a new version of the firmware on the way that fixes the issue described below but something else has just happened. Earlier today I switched from QRSS to WSPR. I've
