Hi all,
1° It seems to me that putting off serial second stage amplifier-
bank for roofingfilters 500Hz and 250Hz and paralleling them with the
others ( 1kHz, 1.8; 2.4; 6 and 15kHz) does seem to be an easy mod
albeit a delicate SMD operation - for the hardware part ( merely
unsoldering or removing right 0.1MicroF capacitors of second bank
and paralleling them with the first bank). Does anybody know if this
has been done?
As well as the sw or hw mod to disable the first bank when the
second is on?
2° A reseller in Germany sells ( probably Inrad) roofingfilters for
the Sub-Rx. Anybody knowing these? Has Bill's (W4ZV) former survey on
this succeded?
Thanks for any hint.
