Re: 417.8 Repeating or Simulcasting RFD CMD 1
460.575 - 417.800 = 42.775. 42.775 / 4 = 10.69375 or 10.7, so your scanner is running an intermediate frequency amplifier of 10.7 Mhz (typical in most scanners) which means you're hearing a 4th order image. What would be the mechanism that causes a 4th harmonic (42.775) to get divided down to near ...

Re: RVC Command Channels
But why is it not changing in the Blythe area? The changes in infrastructure to convert from a simplex support net to a repeated command net are substantial. It would include installation of equipment on the affected mountain tops, programming in all the mobiles and portables, and provision of some...

Re: Old EDACS system off the air
...Just hope they have a fallback in mind. The fallback plan was EDACS. After a certain period of time that the new system is up and running, then the need for a fallback plan diminishes. Any future failures are dealt with, not rolled back to the old system being replaced. That only makes sense for...

Re: Feds still using the RSO West EDACS system
It was RSO's mismanagement of the EDACS system that caused it to be overloaded. Let's hope they don't make the same mistakes.cvrules90 wrote:With RSO on board, the system had been overloaded. Let's hope they can make really good use of the PSEC.

Re: Feds still using the RSO West EDACS system
The BLM has long been a subscriber to the EDACS system. It covers some areas better than their VHF system does. So much for the notion that EDACS coverage was all that bad. BLM uses it more in the manner that it was designed for - mobile radios, not portables. What I would be curious about is what t...

Re: RSO gone digital :-(
Encryption also is a heartache for our media officers. If you remember, when the ERICA system came up, all police-related content was encrypted, but they let the media get portables with the police channels programmed in so the media could still do the reporting. Hopefully, they'll do something lik...

Re: RSO gone digital :-(
I can't speak for the reasoning behind PSEC deciding to encrypt all LE traffic, but overall I think the "live feeds" have contributed significantly to this trend... The ripples cause by live streaming of the Christopher Dorner incident run deep. That, and previous incidents have left LE w...

Re: REACH air ambulance
Dispatch communications are mainly via satellite in the case of Mercy Air and Reach is reportedly on 129.275. Mercy does occasionally use 131.675, however. "Dispatch" operations for the aircraft may be somewhat different than what typical scanner listeners think of. Medical helicopters do...

Re: REACH air ambulance
...I'm pretty sure the helicopters would contact RGH ER on HEAR freq 155.400. I remember being in the ER while a helicopter was talking to a nurse giving a report on a patient, they had a special radio for that. The RGH ER had two radios. One was the HEAR, and the other was the COR, or the Coronary...

Re: Posts Per Day
I never udnerstood what that means. Do you understand averaging? If you posted at a constant rate, 24 hours a day, 7 days a week, 365 days a year, you would be posting a bit less than 3/4's of a post ever day. Also does 21.73% of all posts mean that I make up 21.73% of the posts of the forum? That'...
