Re: [IC-7000] Reception on 6 meters
开云体育One of the stations involved in our test was using an LDG IT-100 tuner on 6
meters.?? The newly installed station was not using a tuner.?

Did you try to use a antenna tuner and push the tune button? that is assuming you are using a antenna tuner for HF 6 meter. ? -------- Original message -------- From: paulgibb@... Date: 11/10/2013 4:17 PM (GMT-08:00) To: ic7000@... Subject: [IC-7000] Reception on 6 meters ? 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

They might have set the antenna up with a duplexer to use it with both
antenna ports, but the duplexer may have been zapped if it wasn't for high
power.

Re: [IC-7000] Reception on 6 meters
开云体育We tested on a repeater frequency, where the TX frequency dropped by 1 MHz
from the repeater output frequency.? We also tested on a simplex frequency
53.020 where there was no offset.?

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. On Sun, Nov 10, 2013 at 7:17 PM, <paulgibb@...> wrote:

Re: [IC-7000] Reception on 6 meters
开云体育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. Mark On 11/10/2013 5:44 PM, brian mackey wrote:

Re: [IC-7000] Reception on 6 meters
开云体育We are using a Comet CF-530 duplexer to connect to the antenna ports – no
switching needed, it happens automatically.

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
开云体育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. 73 de i2jjr - hb9tza Il 11/11/2013 2.40, Norm ha scritto:

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 From: jwsegesman To: ic7000@... Sent: Monday, 11 November 2013, 4:41 Subject: RE: [IC-7000] Reception on 6 meters
