Ultimate QRSS filter components
"ferrymanr"
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 version of the filter section on Veroboard to temporarily convert my 30M board to 20M but used guesstimate values. The only other change was a 14.060MHz crystal. It would be nice if there was a chart of calculated values for all bands.

Hi Dick,
Thanks for the note. In his design Hans used the standard GQRP club output filters which are described here??. I have 14.000,000 xtals in stock if you want to get in the QRSS band. I do plan to do some 20 meter kits in the next run of kits which should be ready by next Monday.?

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 by 30 kHz though. How about a fully synthed Ultimate QRSS kit (for under 20 quid)?? Dick G4BBH --- In QRPLabs@..., Stephen Farthing <squirrox@...> wrote:
