DC IO Freqs

[Hbright]

Does anyone have the frequencies for DC IO-1 and DC IO-2? According to NIFOG, it's a vote-scan system with 9 sites, so it should have a single input freq and nine output frequencies.

I don't believe the freqs on that list are accurate.

They were the last time I was down in DC (3 yrs ago) and nothing has changed that I am aware of
what makes you think they are in correct?

159.15 NAC 653 was active earlier today when I checked

For one, I believe DC IO 2 is 167.25.

But, as a VS system, shouldn't there be multiple output frequencies to correspond with the multiple sites?

Its not a Vote Scan system. Its a voted system. All receivers vote for the best signal. It may be simulcast also.

Correct, the original IO2 was retired in 2010 - seems the wiki never got updated till this AM
Also as already mentioned it is a VOTED not a Vote Scan system

Also, I think the N, W, S frequencies went the wayside with the old IO2, likely because the multi-site simulcast on both IO1 and IO2 has made it obsolete.

The Wiki can be edited by any member.
I could not find the IO's in the RRDB tho....

Heard "Maryland Emergency Management Region" DC IO 1 on 159.15 NAC653 today.

Also have heard Baltimore IO 2 on 167.75 NAC 68F.
