• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

When hikers or others get lost in the Cascades or the Columbia River Gorge, what frequencies or talkgroups do the searchers use? For example, just today (1/6/14), there was a "Sarcom Mountain Wave" truck up on Mt Hood, which served as the communications base for the search. Info on the organization is here, Mountain Wave Emergency Communications

But there is also the Multnomah County Sheriff's Office that does searches in the Gorge, and they probably use different frequencies.

I can't seem to find any for Mountain Wave, Multnomah County, or Washington County either. Do they use low power simplex freqs, or they on the BOEC CCOM 800Mhz system? Even if they're on localized frequencies, there must be a way for them to talk to BOEC or CCOM either way, to radio back reports, or to request further aid.

Do I need to be "up close" to hear the searchers on the ground, or can I hear them from my home in Milwaukie? Any insight on this would be great. Thanks in advance for your help, and happy scanning.... the best hobby of all. :)

Most organizations are expected to be on the state SAR frequency of 155.805. This is a simplex frequency unless a temporary repeater is set up, usually by Mountain Wave in Clackamas, Multnomah, Washington or Yamhill County. When they are working in Clackamas County (most common for incidents on Mt Hood) you will may hear sheriff traffic on CCOM 2 or fire traffic on F4. I know last night there was US Coast Guard and Air Guard helicopters on the incident and they were on 155.805. Mountain Wave also occasionally uses some VHF ham radio repeaters for long distance talk and CB channels for talkaround. These vary by incident location and type.

As a member of Mt Wave, all I can say is...we have it covered if we need to talk back to well, pretty much anyone.

I have heard them on talkgroups 2768 and 37264 when on BOEC.
Glen, are you saying TG 2768 on the Portland 800 System?
No such TG shows in the RR dB. Does it need to be added as MW SAR?

for Pro94Pdx:
I've heard MW SAR coordinating a mission on the Mt Hood NF Forest Net 170.525 MHz,
and I'd imagine you might find them occasionally

From the Mt. Wave website:

"because our primary mission is to enable communications between all organizations responding to a rescue (ham radio is exclusively for the use of licensed hams) we generally operate on public safety frequencies of the agencies we support"

How does this work with that whole FCC licensing thing? Doesn't one need to be a member of a public safety agency before operating on said agency's radio frequencies?

Need to have authorization from the agency. Agencies work together on the same frequency all the time for example OSP on Portland PD channels.


In certain circumstances they may be able to use emergency reasoning to operate on frequencies.

Yes, on the Portland 800 system. The main one used is 37264 with MW ID's. I heard 2768 mainly during the Kyron searches and every once in a while since then.

Mountain Wave uses, among other frequencies, a pair in a repeater, on Goat Mountain. The repeater output is 460.5875 MHz. It is a CTCSS access input. I am not posting the input frequency and access tone, because some miscreant with a $30 Chinese radio would use the data to maliciously interfere with SAR operations, thereby endangering lives.

As a Mt Wave Member, I appreciate that. We don't want to loose that resource and of course if we really wanted to, we can turn on the encryption...
