We did a drill and were able to make numerous contacts on 6m simplex in
that range.? There were many contacts of less than 10-15 miles but the
¡°control¡± stations, which are located in higher elevations, were making numerous
contacts at 10-15 miles.?
You raise a very good point Brian.? 10-15 miles
simplex on 6 meter FM would be a bit of a challenge.? 6M is more line of
sight than the lower frequencies.? You would need a pretty good LOS path
for it to be reliable at all.? Which means at that distance, you would need
some power and good antenna height at both ends.
I have worked 50 miles
on 6M, but I was using a 5 element beam, talking to a 5 ele beam, and SSB.?
Almost no S reading.

don't let hams get stuck on 2 meter repeaters! :)

The antenna is connected to the correct antenna connector?
I am a new member of this group and fairly new to amateur radio.

My question involves settings I might check/change in the IC 7000 to
improve reception on the 52-54 MHz portion of the 6 meter band.? We are
installing about 30 IC 7000s in local emergency operations centers and in
most places we are using a triband 6/2/440 antenna either a Comet GP-15 or a
Diamond V2000A.??
?
I realize these are compromise antennas that are less than ideal on the
6 meter band, but we only need a couple of frequencies on 6 meters to do
some short range simplex (10-15 miles in most cases).? SWR on 6 is
about 1.6:1 at 52.390 MHz. When testing a newly installed station the other
day I was full quieting into a 6 meter repeater about 17 miles away over
hilly terrain.? But I could not hear anyone talking back to me, not
even static, nor could I hear the repeater¡¯s ID tone which the other station
involved in the test could hear clearly.? I checked the squelch and
volume settings and they were fine.? The reception on 2 and 440 is
fine.???
?
Are there settings I
might check or internal filters that might help with 6 meter
reception?? Does this radio have any record of poor sensitivity or poor
reception on 6 meters?? Others believe the issue is related to the
antenna, yet the antenna seems to be functioning sufficiently well to reach
a repeater 17 miles away over hilly terrain.?
?
I suspect there is some
sort of interference that is attenuating the received signal, yet there is
no background ¡°noise¡± showing on the S meter.??
?
Any suggestions or
thoughts about what might be going on would be most appreciated.? In
the meantime we are going to find a couple of mobile units that have 6
meters to do some further testing with.
