Re: [amsat-bb] AO-40 recieving

["Greg D." <ko6th_greg@xxxxxxxxxxx>]

Hi Keith,

#3 sounds similar to my setup.  I modified my Drake 2880
downconverter for a 301 mhz IF (crystal change to put the
Local Oscillator at 2100 mhz), so that AO-40 is in the middle
of the IF passband.  Then I use my ICOM R-7000 receiver.

Using a receive-only IF prevents transmitting into the
converter.  Unfortunately, the R7000 is pretty deaf, compared
to the typical all-mode 2 meter rig.  Overdriving it is
definitely *not* a problem.

Good luck,

Greg  KO6TH

    I am considering the 3 following scenarios for my 144 IF k5gna
    downconverter.
    If you have any experience with these set-ups, any thoughts would be
    appreciated.
    1) downconverter to a hamtronics 2m- 28 Mhz converter to my Icom R75
    receiver. (would this add too much extra noise into the signal ?)

    2) downconverter to a icom PC-1000 computer controlled receiver

    3) downconverter to an Icom R8500 receiver (has vhf all mode-This is
    the
    most expensive,but I can steal it from my brother)

    I appreciate any help. Thank you all in advance, 73, Keith kg2ix
