As Eddie says, I'd use a decent regulator rather than a zener. Also what are you measuring the 1pps signal with ? A DMM might not have the response time to show it properly, especially if it's a

Hmm, get a 3v3 Regulator.:-) Eddie

Hi Eddie, I originally got my 3v from using a few diodes in series off the 5v reg pin. When this appeared not to work I then tried a pot but I may have limited the current too much with the output

Andy Something is wrong re pin7 showing 0.79v. you have applied your 3v supply and here and you would expect to see that value, likewise with pin 8 the 10k should pull it up to the supply

I would say no. What I have done in the past where space is tight is cut long strips of sticky copper foil the same width as the body of the fet. Seems to work ok 73's De

I've got four BS170s fitted to my U2 kit and will be getting it boxed up in the next few days. Is there enough physical space there to fit four of these clip on

Last night I tried hooking up the gps module to the U2 kit. Nothing happened. I had 3v going to pin 7, earth at pin 9 and 3v via a 10k resistor on pin 8 which is the pull up to take the unit out of

Hi all I finally got round to typing all my order details into a big spreadsheet and doing some statistics. From time to time I'll update the charts. 1) The number of LPF kits that have been ordered

Reyax UP501 modules work perfect with U1 and U2. ?17 a piece on Ebay. 73 de Andy

Thanks for posting the image Eddie, My signal looks ok, I've never really studied what a wspr signal should look like but mine seems to be able to be decoded on any band. Current status with my U2

Hi Eddie, Thanks for your reply I will give your idea a try. 73 Colin

Hi Group I will start a folder of captures of the U2. To start it off here is GJ7RWT U2 on WSPR this morning. There could even be other U2's there, mine is shown but is merely on soak test into a

Hi Colin Instead of square waves you may be getting a low level squiggly sine wave as drive from the DDS, try adjusting the blue potentiometer on the DDS board for equal mark / space ratio on pin 7,

Hi to all members. I have just finished building the LPF's and I get about 500mW on 160m up to 17m which is about 300mW and then for some reason 15m = 70mW only and 12 and 10m must below 10mW (my

"Well I suppose if it's possible then that would be a nice addition, *but I'm sure you have better priorities in life ;-)*" I took the liberty of 'bolding' the important part of the message. G0BZB

Hi Andy I'm very glad that you are enjoying yourself with the kits! Thank you for the patience while I sort out the issues. We have a lot less issues this time than with the original "Ultimate" kit

Hi Hans, Well I suppose if it's possible then that would be a nice addition, but I'm sure you have better priorities in life ;-) At this point I'd like to thank you for all the work you have put in

Ok well I think I have space for it. I removed a feature which I have never heard of anyone using which is the "Inv FSK" feature. Removing that created a little more memory. 73 Hans G0UPL

Andy No complaints if Hans can do it without stealing memory from other wishes but are wide beacons not the domain of of official and more QRO beacons? Not sure here how QRP would

Hans, here's just a few references
