hi,

here's my question - i have 4 radios that i'm testing side by side. a
palstar r30cc, kenwood r-1000, kenwood r-5000 and an icom r71a. i have
a 100ft. endfed longwire antenna strung up between two trees. when i
hook the antenna up to the palstar and r-1000 i get excellent reception
below 540 khz. the palstar's tops, but the r-1000 holds its own and
picks up most beacons that i have logged. when i hook the r-5000 and
the icom r71a i get nothing but noise below 540khz. i can hear some
beacons but they are faint and in the backround with lots of noise on
top. shouldn't it be the other way around? these sets in their day cost
in excess of 1000.00. is the palstar that much better or is my antenna
wrong for these radios. i have the antennas hooked to the longwire high
Z inputs on all the radios - would the r-5000 and r71a perform better
with a coax fed into the 75 ohm input - such as a dipole. why are the
less complex radios kicking butt? is it possible that the internal
noise generated by the icom and kenwood is causing the problems. i'll
admit that my antenna is pretty simple, but i logged many low power
beacons from western canada with it and the palstar.

JOHN,

# 1 - Try a simple C-L-C "Matcher" between the Antenna
feed-in-line and the Antenna Input of your Receivers.

# 2 - Ensure that the Matcher is very well Grounded.

-or- # 3 - Place a Magnetic Long Wire Balun (MLB) -type-
Matching Transformer {actually an UnUn} at the point the
Long Wire Antenna Element meets the House and use a
50 Ohm Coax Cable from the MLB down to your Receivers.
Ensure that the Coax Cable is very well Grounded at the
Receivers.

hope this helps - iane ~ RHF
