One thing to keep in mind - the 39 mhz freqs are all simplex - that is, they are not picked up on one freq and repeated on another - so hearing them is something of a challenge. On occasion, they will use the 155.73 portables freq (noted fairly frequently here in AA county), but you still need a good antenna to hear them.
In some places (Eastern Shore barracks, Carroll county for example) you can hear MSP on the local trunk system.

Using the local county's trunked system has rapidly become a way of life for the MSP. Not only the counties mentioned above, but Harford, Howard and Montgomery Counties all have MSP talkgroups that interact with the county police within their systems. Rumor has it that Anne Arundel County will soon contain MSP talkgroups too. In the near future there will be few, if any, MSP barracks other than in the far western counties that are not a part of a trunked system where you must rely on the 39 mHz signal. All the better.

Frederick and Carroll barrack both operate off their respective counties trunk systems, as well as simulcast on their usual channels. MSP G in Carroll still has a strong signal on 39.520.

MSP Saint Mary's county are on the county trunked system and simo transmissions on 39.38 MHz. They sometimes use an obscure VHF channel for TAC use.

Does anyone know for certain if MSP still uses 155.73 MHz for their mobile extenders in Saint Mary's county? I have that frequency in my scanner(s) and have yet to hear anything in the last 1.5 years I have moved back to Southern MD.

Do you happen to know what frequency the VHF TAC channel uses?

Yeah, the troopers do not have them in there helicoptors yet.

The only freq I hear on a regular basis is the 44.74 SysCOM one. Add 47.66 along with that one - also used regularly. The others I've never heard although I've had them programmed forever.

I've never heard activity on 44.9 (since the 80's, when there was some radio testing). As for the two low band freqs for the STATE Team, I never heard squat on them during a few recent operations - although the 159.405 low power portable freq was very much in use.

A while ago, someone on our board suggested that 47.5 is an alternate heli-med freq (when 47.66 is very busy)....but I've never heard it used as such.

As mentioned, they use the 47.66 very frequently - almost every flight - to report patient condition to the hospital while on the way. Since the signal is airborne, it's a very easy frequency to hear even without any kind of special antenna. It's generally where you can get the real information on an incident, the circumstances of the accident for instance and what happened to the patient to cause the injuries he/she is being transported for. It's worth having in the scan rotation.
