Read here:

Their 10-month extension to delay the narrowband move was granted:

So does this mean something like Tait systems?

I had a chance to re-read this letter. I saw this the first time but it didn't register.

So it sounds like PSE is dumping their 900mhz EDACS system and VHF/UHF systems and moving to 217-220 Mhz MPT-1327 system..?

Doesn't this seem rather odd? Does MPT-1327 give them some great feature that another mode cannot?

Some low speed wireless data where they don't have it now.

Im sure a consultant is involved.

Their channels are pretty clear to be abandoned so readily.

Did I say that outloud?

Looks like PG&E in CA is also MPT-1327. Probably just followed their competition. ;)

The new radio system is not compatible with any of the existing radio systems or mobile transceivers currently used by PSE.


Interesting. Not compatible with their existing MPT1327 systems near Ellensburg or Dayton?

217-220??? Maybe up to 222??? Sounds like the Securicor salesman talked a good line...

Geez... A decade ago Peninsula Light Co. started a "wholly-owned subsidiary" called Northwest Telecommunications Co. to install a statewide network of similar gear and due to lack of customers tore the whole thing out a year later... The other problem was the intersite networking didn't perform as advertised. Mobile units and handhelds cost a small fortune compared to NBFM, and the handhelds were monstrous. I have one of the base station radios here... the SSPA will make around 100W PEP on the 222 ham band :mrgreen: Guess I will keep the SSB RX gear a little longer :D

I saw this a few years ago. http://www.taitradio.com/news-and-media ... -with-tait

Besides this one on Zetron's website: http://www.zetron.com/News/PressReleases/pr_072811.aspx

220 MHz -- can you say expensive?

A very rare standard, with support from NZ, and in a spectrum not used by many. This will be a piece of cake to operate and support.

Did some searching of the 216-220 range and found the following using trunkview. I'm still new with this software and protocol so bear with me.

217.5675 ID:5169 PL:146.2 (Possibly a different system?)

217.5125 Possible voice frequency? Morse code every so often.


I can't seem to find any of these frequencies licensed to anyone.

PSE bought the spectrum range from auction. I don't believe the FCC requires individual frequency licenses in that case.

Thanks for that Nick. You're right:

So it looks like this may actually be the beginnings of their new systems! Still no voice activity though.

After seeing some repeaters are located in Whatcom County I searched and found constant data on these freqs.
Received from Bellingham.
They are approximate.......

217.645
217.695
217.945

In Bellevue here, I'm getting:

217.5025
217.5075 @ 110.9 & CWID
*217.5425 @ 110.9
217.6775 @ 146.2
217.6825 @ 146.2
217.7675 @ 146.2
*217.8175 @ 110.9
217.9825

* = full-quieting

Will try out Trunkview here later tonight.

Getting 50B1 as the ID for 217.8175. Can't seem to get the others to decode. (I'm using SDR# and RTL for audio input) ... may have to try audio patch from PSR-800.
