OK Tony, I managed to stay inside the WSPR band. However I think to be in the bottom of the lower part but yes it's enough to work. I am a little puzzeled with the freq you announce. I really think to

Yes Gerard, I spotted you five times last evening and my record shows that you were at about 10.140190. This is well into the WSPR band so do not worry about changing C5. You are already there and

Hi Tony, Thanks for your message and hints. I will try reducing C5 value once more. By the way I saw you spotted me several times in the last 24 hours around 10140.130. Best 73's. Gerard.

Gerard, I had the same problem when I started with the kit. I replaced C4 & C5 with 18pf and the frequency went up to about the middle of the wspr band. Replace C5 as well as C4. Also, I have found

Belle journ???eHi all ! I just finished assembling my U-QRSS-Kit for 30m. It seems to work fine at once except the frequency. I couldn't get it higher than 10 139,840 Mhz with adj C8 at minimum. I

Hi Philip , thanks for the spot I also had a spot into Florida USA this mornig from W3HH, a distance of 7508 Kms, SNR -24. QRPp rocks yer socks off. 73 Colin

Hi Colin I spotted you this evening at 20:30 and 21:10 Running my Softrock transceiver today whilst I'm finishing boxing my UQRSS rig.. Philip G4JVF

Sorry for the typo the batteries are only 2000mAH

From my experiments I believe that once drift due to temperature stabilisation is taken into account the major cause of further drift is variation in supply voltage. To my mind the oscillator

Thanks Steve, this kit has been one of the best I have built and has a huge fun factor, I will be up in the hills at our QTH on Sunday and look forward to seeing the results on WSPR using a small

Hi Tony, many thanks for your reply, you are right with the 30m band, I have noticed two 10 hour periods during the night with no spots, I am suprised that I can tune up as far as 10.140260 as my Xtal

Hi Colin, Mine will drift too if not disciplined by GPS and will happily move 20htz overnight if the GOS is off. I have not 'destroyed my pcb'. I think some crystals are more free spirited than

Colin, Well done and thanks for the report. Glad to see you are getting some enjoyment out of the kit. 73s steve G0XAR

Hi, I have been running the U-QRSS kit with 4 AA, 1.4v 8000mAH rechargable batteries on WSPR with FRAME set at 14 non stop for the last 30 hours, on my first try I used batteries I had forgotten to

Thanks for the link Steve. I had not been aware of that. I obtained a couple of 14.060MHz crystals recently. Not really high enough for WSPR but these can be pulled a bit. I doubt if they will go up

Thanks Steve. I have taken a break from the pileups and worked on the beacon...it was off frequency and out of band it is now corrected. 10.140MHz and a little high. On RX dial 10.1400000 Argo says

Hi Dick, Thanks for the note. In his design Hans used the standard GQRP club output filters which are described here output filters<http://www.gqrp.com/technical2.htm> . I have 14.000,000 xtals in

As the Ultimate QRSS should work on all bands up to 17M I wonder if a set of component values for the output filter has been calculated for bands other than the three bands listed. I built a 20M

Hi Bob & Steve, I have corrupt characters in the following menu options: (a) SPEED 003!VG (Should be 003) (b) Frequency 1001400000 (Should be 10,140,000) The Speed is OK as I can do

Guys, Dom is active on 30 meters QRSS3 using a G0UPL Ultimate beacon from 6w land. Please keep an eye out for him. 73s Steve
