MEMA UHF Boston.

#1 Post by Captain Strobes » 17 May 2018 09:05

Has MEMA UHF gone off the air in Eastern Massachusetts. Have not heard them in several days, but are still hearing them on the 800 and VHF. Anyone else noticing this?

Which UHF frequencies? I was only aware of them on VHF and the MSP trunk. The VHF frequencies are pretty quiet for me but I def hear them on the MSP system.

MEMA has a UHF frequency for interop with MBHSR agencies. 471.6875 NAC606 is MEMA Metro, however most MEMA Broadcasts that I hear in the Boston area only come over the Boston VHF Channel (153.9650) and the MEMA Statewide TG (38896). I only really hear the UHF channel active during special events.

The freq was 471.6875 with a DPL They had been for the last year patching the vhf and 800 tg’s to it. I had been monitoring daily, hearing mema and weather alerts, along with the covering supervisors from dep calling off their locations. It just in the last week it went silent.

I changed it to P25 in my scanner as it was being used in P25 mode NAC606 during the 4th of July last year (and I believe the marathon as well?, but I don't remember :pint: ). The analog side should be DCS606, I will put that back in my scanner since it appears they are using the channel in duel mode. It could be an issue with the repeater or possibly just that the dispatcher forgot to add the channel to the multi-select.

Ah, that explains it - I only recently upgraded to P25-capable scanner and so did not have this in my frequency list yet. I added it and just now heard the 8AM radio check on the Boston UHF channel.

The MEMA UHF Analog base station is being replaced.
We anticipate having it back online next week.

Thanks. Are all the doubled frequencies in the Region 1 table dual-mode? Should I program them in as separate channels, one analog and one digital? Still coming up to speed in this brave new digital world.

If they indicate Dual Mode and/or have both a PL/DPL and a NAC Listed, it would be suggested to
a. Do two entries
b. Enabled them as Automode for the scanner to switch back-n-forth instead of suggestion a.)

All the MEMA VHF repeaters are dual mode.
Analog is wide area voted, multicast.
P25 is local, most often used as a tactical channel during incidents.
