A number of hams in Kitsap County have discovered some sort of digital transmitter on this frequency. :puke:
I need to insert 50dB of attenuator to make it go away... It can be heard by mobiles near Sultan, WA,
and my horizontally polarized directive array seems to show the most signal arrives from a North-Easterly direction, here in the South end of Kitsap County. This has been verified by another similarly equipped station to the West of me.

What is this thing???

Can something be done to make it "go away"??? :mrgreen:

Maybe you posting did so. I haven't heard a peep there.

The transmit/receive sequence now has considerably more "no signal" than "signal" (if you could call it that) at this time. A couple hours ago it would transmit nearly continuously. Now only occasionally, but I am still hearing "stuff" there and at least 6 transmissions in the period it took me to type this.......

How about an audio clip?

Been running almost continuously since around 0700 local time.

From what lat/long are you not hearing it at???

Well I ask because you did not mention in the first post it was a voice transmission. Thus why I asked about an audio clip.

Anyway, I have not tried to monitor yet. So I can't say I can hear it or not.

I tuned in this freq last night and this morning. Last night was down by Costco on 527 and then today North Lynnwood to the Boeing Everett plant. Did not hear anything on my portable with dual band Diamond antenna.

Is their a reason for the non standard split? If you know?

Nah I have no clue.

a 1 meg split? they might be using a smaller commerical duplexer.

Well I wonder if the (expletive deleted) who put this on the air even bothered to coordinate it...
But using a pair of "simplex" frequencies instead of a "band-plan standard" repeater pair they might have snuck this one "under the WWARA radar" so-to-speak.

Wish I had a :chaingun:

Same repeater is on 70cm too. Uses the standard split in this case however.

70 Centimeters (Usually "B" Node): 443.42500MHz +5.000

Eric, this would be my guess. Rptrbk shows repeaters that have been coordinated thru WWARA and this one doesn't imply this...

Repeater coordination are just glorified suggestions and if you are smart enough, you can do research and find space and no one would notice as long its a low level repeater :P
