Thanks for confirming that for me Chad

Anyone know what the base frequency or frequencies are that are being used by the subscriber units (not on a scanner) of this system? I assume it's 450.0000 but i'm not close enough to monitor.

Huh?

Typical +5 mhz split.

xxx.xxxx repeater out
xxx.xxxx + 5.000 = repeater in (mobile transmit freq)

Typically [but not always] on SIRN, the trunked system transmitters are on 453 and 460 mhz whilest the radios are transmitting on 458 and 465 mhz respectively.

On an OBT trunking radio, there must be a base frequency or series of frequencies set so that the radio knows where to begin counting up from in steps to reach the correct voice frequency. It's similar to the band plan for a Type-II system when programming a scanner, it just applies to the radios on the system.

Just wondering if anyone knows what it is.

[OldDeadOne]

You are talking about the RADIOS and not SCANNERS,correct?

[BigLebowski]

Yes, radios as in the XTS5000 or XTS2500.

[OldDeadOne]

As far as I know we are not privvy to law enforcement or emergency or fire radios,why are you asking in this forum and not in your north carolina forum?

[tipsymedia]

Looking to buy a few digital radios.... anyone know of any cheap Chinese Mfg. Brand radios that will work on the SIRN?

I saw Hytera has DMR radios

DMR Series - Hytera Communications Corporation Limited

Would any of these work? If not any suggestions?

We are looking to get radios for all of our crew members for our EMS agency.

I understand this.... I am working in conjunction with my Ambulance Authority in hopes to ascertain digital radios for all the squad members.

Because I am asking specifically about SIRN. If I had a general question I would have posted it in the Motorola forum. It can be different for every system, so here I am in the WV forum since the subject at hand is SIRN.

I'm sure someone on the board knows what I am talking about and can hopefully answer my question, which is just a simple question and there is no need to try and read into it any further or jump to conclusions.

Sir, just want to let you know, only certain radios are authorized for use on the system. It can be found here on the SIRN approved equipment list:

Also on this page you may find a participation application as well...any agency wanting to use the SIRN needs to go through a process and be approved, not to mention have a certified radio programmer program the assets procured. Further info can be found on the website provided above.

Good luck!

bixlerjd: Great link..... I think for his radios he should apply to have his radios done in his state,practically useless for those radios here....

Bert - you may have missed that there are two different people asking questions about the radios - one out of state, and one in Elkins. The one in Elkins is looking to get SIRN radios.

[OldDeadOne]

I know about the one in Elkins,I was commenting on the one in NC,Mike....

The Raleigh County Sheriff's Office recently got a good deal on digital radios from Electronic Communications located in the Kanawha Valley. Might be worth asking that company for a quote or a bid. That's not a recommendation to buy from them but rather a recommendation to get more info.

What you need to use on the statewide (SIRN) system are P-25 digital radios, not cheaper DMR digital radios.

The Construction Notification "suggests" that the site has been built out; however, that does not mean the site is active. One or both of the sites may be active or may become active in the near future.

Those living in the above general areas should be on the lookout for newly active SIRN sites in those locations.

Wiki Info for the above two sites (ignore the 900x site numbers)

Be on the lookout for active control channels at those two locations based upon the frequencies listed in the Wiki. Additionally, they could potentially come online using control channels in the 454-455 mhz range, so it would make sense to also periodically scan that area for a potential new site as well.

If you happen to discover a new site online, please post the info here and submit it to the DB as soon as possible so that others may benefit.

Thanks

Mike

Control channel of 453.6625 found. According to the wiki it is from the Circleville tower in Pendleton County.
