Trying to locate station on 156.1500

[Searay]

Hello all. I am trying to locate a station transmitting on 156.1500 with a PL tone of 162.2. I can not tell for sure but I believe it is a base sation not a repeater, but not for certain. A search of the database for an identified freq does not reveil anything with thet freq/PL combination. A search of the FCC records shows one that I may suspect as the station I am trying to pinpoint.

156.15000000 20K0F3E MO 250 0 60.000
156.15000000 20K0F3E FX1 1 0 45.000 ASHEVILLE BUNCOMBE NC

I have heard transmitions using MDC signaling as well as DTMF signaling of some sort. I know that Buncombe County fire (155.6100 / 103.5) also uses the same type DTMF signaling. If anyone can advise if the freq in question is being use in Bumncombe county, or elsewhere with that PL that would be great. Experiencing some interference problems in SC and just trying to narrow down the source.

Thanks,

Matt

Hi Matt,

I can't help you because I'am way to far away from that county. We are having a propogation problem with everyone hearing each other on VHF. Alot of ham radio operators enjoy it cause they can talk father. But Hopefully somebody can help you out alot better than I can. I can tell you that cause that's why your hearing it from South Carolina.

Good Luck!

We are located in upsatate SC and unfortunately we have to deal with stations on freq with us quite regularly. Stations up in the mountains and foothills effect us even when propogation is not an issue.

Rutherford Co. SD uses this frequency as their channel #5 according to my records, with a tone of 167.9. Could they have changed their tone?

156.150 is indeed used by the Buncombe Co sheriff, but it is the mobile or control station side of the system. You may wish to monitor 155.430/91.5 to see if you are hearing the same traffic, this is the FB2 side. 110.9 is the normal encode PL, but IIRC, 162.2 is also used (This is a simulcast system).
If you can copy some address info or dispatches, with some local references, I may be able to confirm or eliminate the Buncombe possibility.

Matt --

Can you let us know what you are hearing? Give us an address or the type of communication that is being transmitted so that we may be able to use Dispatch methods or type of traffic to help you further!

Thanks

It sounds like EMS traffic that is being repeated, but the signal into the repeater receiver is so weak it makes trying to recognize any addresses or landmarks impossible. It is narrow band.

It sounds as though there is more than one system involved here. It sounds like 156.150 PL162.2 is an FB2 that is hearing another FB2 on its input frequency.

What I am getting at...if I could actually make out any of the traffic, I would probably be hearing the repeater that is being repeated by the offending FB2. Does any of that make sense?

 

[delta85]

I have "pretty much" determined that what is being heard on 156.150 is the repeat of a repeater (repeater repeating a repeater). I have decoded the MDC signalling and determined that the code that is being sent after each transmission is 7999.

Other than that, anyone's guess is as good as mine as to who this is.

Thanks for any input!!

Searay - QBall mentioned you were working on this one.

I've had alot of time to monitor this one in the past 24 hours. I concur ... the MDC signaling is on a repeater channel, with a fire-rescue agency being repeated by the MDC repeater.

The fire-rescue agency is also using a repeater, but I have heard NO call dispatching on this channel.

I have to think the MDC signal is coming from an agency within normal listening range. I have been able to hear the signal throughout the day, with little dB variation in the signal strength (using ScanStar to measure the signal level).

The one problem with this being a repeater is that the only license for 156.150 as a repeater output in the SC / NC / Tn / Ga area belongs to Cobb County. The City of Smyrna in that county is reportedly using the channel for PD, but I have not been able to find any useage or tone information for them. Cobb County is well out of my 'local" monitoring area, though, and I have not run across any other activity from that region in the past 24.

ANYONE KNOW WHAT WILLIAMSTON PD (Anderson County) IS USING 156.150 / 153.755 FOR ?

The reason why I ask is that Anderson County law enforcement typically use a PL tone of 162.2 on their channels. In this situation, the license says 153.755 is the repeater out, and 156.150 is the repeater input ... but agencies have been known to reverse the repeater pairs without the sanction of the FCC.

Either the interfering signal dropped back into the depths of white noise, or it's gone. I haven't heard it since yesterday afternoon.

 

[jeffmulter]

Have we come to the conclusion that the interference to the York Co Sheriffs channel was related to the problems Buncombe County was having with their F1 channel ?

I would tend to believe that the interference problems were on in the same. The problem disappeared late last week.
