Why are yours neater than mine Keith? :) Philip G4JVF

I've been doing the same... http://www.feek.co.uk/images/lowpassfilters-20130727-112046.jpg Just waiting for the others to appear in the shop. 73 Keith, G6NHU

Tom, I think that on the LPF boards, the "overkill" silk screening showing the inductors, could be used to show an image of the US resistor sysmbol, but marked as L1, L2 etc, indicating exactly which

Don, your numbers sound about right, though all of my testing has been at 80 meters. In the files and photo section you can see some screen shots of what I found there. On 80 meters I can get as

Hi John The display isn't backlit. I am considering this for future versions. 73 Hans G0UPL

Barry , I plan to use one of mine on 472 kHz. also . Would you mind sharing your amplifier drawing ? Best Regards. 73 , Charlie , W5COV

I hooked up the unit on my OCF dipole up maybe 30 feet. Tried 30 meters with lots of stateside WSPR reports. Then put it on 20 and its been up for a while. Numerous world wide reports including

I took option 3 as a quick " get out of trouble route" and have powered it on now. I thought I had some push to make panel mount? buttons , but did not find them, so ordered some off ebay. I will

------------------------------- I was somewhat confused on what holes on the LPF boards to stick the toroid wires through. Also, some of the holes were somewhat filled with solder plating making it

Barry, with my transverter, I just need a 80m signal to drive the IFR? which gives me 10w out. This design currently has a crystal oscillator and a ADE-1 mixer used in TX mode. On Rx it uses the

Paul, The U2 is getting well! With the software I have (a few days ago), I was able to get my 5 character call in just fine. I think Reset helped a lot. And editing wasn't done right yesterday. Plus I

Hans I've just uploaded a file showing my mods to the U2 kit to drive an external class E PA. My main interest is using the U2 on 472kHz but the same idea would work for other bands. At present my PA

I just looked at the charts and they are in the Photos section (since they are graphic files... and they display better there than in the Files area...) under "WSPR TX Times". On 30 meters, the

Don, The original problem was in the callsign - WSPR requires a 6 character call. Yours and mine are only 5, so you have to add a space at the end in the callsign field. Then the error "Message"

Hi John The default fuse setting on the AVR is for the internal 8MHz RC oscillator, and the divide-by-8 fuse is set. So the effective internal clock speed is 1MHz. 73 Hans G0UPL

I run mine on START =0 FRAME =4 This means the kit is transmitting for 50% of the time it is on. People using using standard PC TCEIVER setups, often have much larger frame values which produce a

Yes Gary, I did catch that early on, but not the trouble. Finally, the no output went away with Reset, and re-doing the options. I think I didn't understand the editing of configuration. It looked
