Hello  Alan, Scott and the list,

 Thank you for the infos, very interesting in fact, this band is not so
empty, good!
On front of the receiver i use a bandpass filter ( Cheb.  .2 dB ripple, 11
KHz BW , 7 poles)
to reject part of "QRM", the mixer is a SRA8 from MCL, the LO is a 5 MHz
OCXO
and some MMIC in buffer. The IF is a FT847 with 300 Hz Xtal filter.
My main problem is that the loop antenna is ~120m (~390') from the station
and i pick up
some crazy thing by the braid of the coax cable... The new preamplifier (two
match U430 Siliconix)
and CV tune system is not finish at this present time. Give me some time, i
am a novice,
just escaped from VHF!

Very deepest 73: Jeff
