Re: [IC-7000] Reception on 6 meters
Yes it is. We are using a duplexer (Comet CF-530) that connects to both
antenna ports.

Hello All -
?
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.
Thanks, all -

Re: Kenwood AT-250 tuner to IC-7000
I don't know why you'd catch flack for it.
Here's a link to a manual for the AT-250.?
As far as I can remember, you only need to interface the AT-250 if you want it to track what band the radio is on. ?That might be an issue - again, as far as I remember, that only functions with Kenwood rigs, and really only works well with the TS-430. ?Fig. 3 in the above-referenced manual shows the pinout for the control jack on the back of the AT-250, but heaven knows if the band data supplied by the IC-7k will be understood by the AT-250.
Note the AT-250 will do everything else it's designed to do - switch antennas, automatically tune - with any rig, so long as you reach over and flip the bandswitch to the desired band. I had a complete TS-430 station some years ago, and it worked FB.

Re: [IC-7000] Reception on 6 meters
You may also use a diplexer like the ones of Comet. They have two
inputs: hf and 6m, and v-uhf (144 & 432).
These shall be connected to the two rigs output; and the diplexer
output connector goes to the coax to feed tri-band antenna.
I did this way years ago , and was working well.

The 7000 uses one antenna connector for VHF/UHF, and another for
HF (thru 54 MHz).? Using a triband antenna, you must switch the
triband antenna between the transceiver antenna connections when
going from 6m to VHF/UHF.

Re: [IC-7000] Reception on 6 meters
Hi Paul you do realise the 6 meter output and receive is on the HF port of the radio not on the VHF/UHF port. a common enough mistake to make.??????????????? Best regards robert G6LLP

as easily have the height/site advantages that are more common on

Since you're able to get into the repeater, I'm assuming you have
the antenna connected correctly - 6m is on the HF antenna port, 2m
and 70cm are on the VHF port.? That means a diplexer is needed.

Re: [IC-7000] Reception on 6 meters
Perhaps use a duplexer, such as a DIAMOND MX-62M, instead of switching to and from the HF and VHF/UHF connectors.

Re: [IC-7000] Reception on 6 meters
Are you sure this was simplex, or were you on a repeater-freq. On certain sections of the particular bands, the radio automatically becomes a half-duplex radio: different rx & tx freqs.
When you key the mic, make certain the TX freq doesn't change from the receiver's.

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.
Thanks, all

Re: [IC-7000] Reception on 6 meters
The antenna is connected to the correct antenna connector?

Hello All -
?
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.???
