In a recent topic comments were made about the value of having a CW filter for the FT-817 - well…
Recently I had my grey matter befuddled by an over-enthusiastic and somewhat unruly response to my calls on 10.116MHz, so I was pleased at last to take delivery of a 300Hz Collins filter from W4RT Electronics today… and all I can say is WOW! I thought the 500Hz filter in the TS130V was good, but this is the RF equivalent of Striding Edge. Having just worked EA6/EA3ADV/QRP on Majorca on 10.115 who was using a K1 and a long wire (reports 449 in / 429 out in QSB and QRN), I switched to the SSB filter and found a pile up happening on the doorstep, well within the SSB passband with many signals at S9.
Seems I just might be able to cope a bit better the next time I’m out on a summit in the rain.
