Add another ham repeater to the P25 list:

145.130(-) N1CIV/R Norwich, VT

Input is mixed mode, analog/PL100.0 or P25/NAC293
Output is analog only w/PL100.0.

Feel free to add it to the map.

Keep your eyes open. I picked up my VHF Quantar for $2k.

Hey Mark

Do you plan on making the 442.000 repeater P25 In Boca. And is the one in Riveara up on the air I just installed a 100 watt w3 in my work truck and wanted to give it a try.

Thanks
John

John -

Yes that is the plan. I have some modules on order to piece together a box that I have. 146.88 has been up for a while and P25 capable on the north end of Singer Island at 280'. I go back to work next week so let me know when you want to try it out.

Qsl , I am going to program my mobile this week end. Let me know when you get the parts together and if you need any help with it. I am currently working on installing a Arcom controller on the 146.925 repeater using the MRITI port on the back of the station.

OK, so my xts3k come via fedex this afternoon, iv scoured the net and cant find anyone else using P25 in the metro DC area (aside from all the black SUVs with lots of antennas that dont stop for red lights, but i dont think they want to chat with me). is there anyone out there for me to talk to....anyone...helloooooo?

I don't have anything for P25 in metro DC on my map as of this writing and there isn't anything in the latest repeater directory.

We've got another one up in Palm Beach County, so I'll list off the ones that we have in South Florida as one comprehensive list:

Palm Beach County
146.88 - PL 110.9 NAC 293 @280' in the Riviera Beach/Palm Beach Gardens area
147.36 + PL 110.9 NAC 293 @ 370' in the center of Palm Beach County
145.39 - PL 110.9 NAC 293 @140' in the immediate vicinity of the Palm Beach Intl. Airport
147.39 + PL 110.9 NAC 293 @340' in western Boca Raton
All of the PBC locations are public safety radio sites with full back-up power.

Broward County
146.79 - PL 110.9 NAC 293 @ Motorola Plant in western Fort Lauderdale
443.00 + PL 131.8 NAC 293 in downtown Fort Lauderdale

IS possible one system transmit in apco25 encrypt comunication with analogical repeating stations, all in VHF/FM ???

Try that question again, but read it before submitting.

I think I know what you're saying. If it's a Secure capable Quantar, it will pass DES-XL [analog] /DES-OFB [IMBE]. I'm not sure about AES-256 - but I can't see why not.

If a Quantar is configured to pass analog encryption it will not support digital mode. It's clear analog or 12kbit analog encryption only.

Decrypting a digital encrypted call and then patching it to a DES config'd Quantar, via CIU (or DIU?), isn't worth the costs involved. I'd hate to hear what it sounds like too.

My P7100's have a very interesting front panel programming option. I can modify any channel in the radio from the front panel, changing frequency or tone or NAC or whatever. But it is a temporary scratchpad. In the front panel program sequence there is a menu option for "restore channel" which puts it right back to the way the computer software had it programmed.

I have one of those, too. The FPP option is restricted, and I'd guess that your radio has "all" 40 options? Ø Like mine? I can put that feature set into ONE more radio.
(Transfer the DS2401 chip and the associated feature string into the candidate radio.)

I find the FPP option on the 7100 to be very handy in the field. Though the radio is
undeniably cheesy, with sucking audio quality both transmit and receive, and it has its
share of faults such as very slow response to when a control is manipulated, which I
attribute to its being overloaded with options, it's still very handy in the field as I can
program it quickly to check or talk with any other radio I come across if I can find its frequency and tone data. It can even be programmed for digital. I'm often in one
county where the sheriff uses digital on their VHF channels. So I listen in.


Earlier you said something about radio toughness...M/A-Coms aren't very tough, actually. Not these days. A fire truck WILL defeat the aluminum back housing's strength of a 7100IP, this
I know for absolute certainty. Been there, fixed the radio...by throwing out everything
but the PC board and replacing the fuse on the PC board, then putting that board into
a complete new radio kit. Housing, shields, display, display board, the whole nine yards...

I'd say that Motorola's radios are tougher than any newer M/A-Com radio. When they
went to the plastic front housing they lost their crush resistance. It was tough to really
bust up an M-PD or M-PA. They were very fire truck resistant.



That Frappr map doesn't work for me. But I'd like to know about the IMBE capable
repeaters in central Florida all at once.

I don't have any listings nor do I know of any IMBE repeaters in central FL, only in the South and in the extreme North areas of the state.

There are several of us in PG and Montgomery County MD that do P25 on Simplex on the Amateur Bands. I am trying to get a UHF machine working so that I can replace the conventional repeater our club has with a mixed mode machine.

shoot me a PM if you are interested.

 

[CqDx]

Anyone planning to put up a VHF IMBE machine in NYC?

 

[N_Jay]

Why do people insist in calling P25, "IMBE"?
