No, I have been around, just too busy to keep up with all the threads. I wish there was a ¡°Status¡± page that could keep everybody posted on progress.

Thanks,

David,

You must have missed the last three months.... and a pair of very long threads!? ;)

To clean that up yes, band pass filters are the option or some very fancy combination of
high pass and low pass which results in the same pass band as a band pass.

Generally the in band spurs happen to be extremely weak and as such not a worry
other than being annoying on receive.

Warren,
?Thanks for nice job. We never get these vertical type relays. The filter caps may be? 3? for each section, ? so that the user? could reach closer value of capacvcitor by a combination.

Hi Kees

I would be honored to test and record data, publish if you wish, any filters you would be willing to send. I would of course return them after testing is complete. If you would like to proceed please contact me privately for shipping info.?

Thank you Kees.?

Thank you for the great suggestion. This design is not from me. It is the work of?Kees K5BCQ. I agree...... a very nice job and I look forward to testing it.

David,? the web page has a wiki...

Maybe the mods could harvest info and post there or borrow from mike at ubitx.net.
