Re: Kenwood AT-250 tuner to IC-7000

[email protected]

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.

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.

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.??

?

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.

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

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.?

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??

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.??

Except that 6m FM seems to be more susceptible to local electrical noise than 2m.? And because of the size of antennas, etc, many don't as easily have the height/site advantages that are more common on 2m.

But yes, all things the same, 6m would seem like it would be comparable to 2m.

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.

Assuming the antenna is properly connected through a diplexer (or switched to the HF port when on 6m), there does seem to be something amiss with your reception.?

Perhaps use a duplexer, such as a DIAMOND MX-62M, instead of switching to and from the HF and VHF/UHF connectors.

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.?

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.

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 -

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.??
