As you are no doubt finding out, the average ham radio has 25kHz IF filtering and +/- 5kHz (or more) TX deviation with little or no modulation limiting. Your choices for equipment that can resolve

These units are sold, thanks for all the interest.

Can I make a suggestion?? Of course, I don't know your specific situation but our experience is that jerkoffs who do that crave negative attention and would actually jam just to get us to turn the

The Motrola CDM series will also narrowband and are great mobile radios The CDM 1250 and CDM 1550 (my favorite) Lloyd KO4L [email protected]> wrote:

Almost any Kenwood with the model TK-7xxx will do those splits. The Kenwood repeaters TKR-750 and 751 will also do those splits. Roger, N5QS

Hello Tim, For mobile radios, the M1225 and CM300 will both work for narrow band. I would be very sure the P1225 and CP300 portables will also. Mick - W7CAT

I meant to say Part 90 services..... -- The Real RFI-EMI-GUY

When the FCC (AKA Motorola) mandated narrow band for Part 95 services, they forgot that a small number of VHF channels, primarily VHF mutual aid channels required 2.5 KHz resolution. Because

Hi folks, I'm in Wa. state and WWARA has authorized me a NB rpt. pair 146.6875 out / 146.0875 in. (2.5 kc / 12.5 kc ch. spacing) My rpt. is a Motorola Quanter. I now am searching for compatible radios

One wire, ground, should be easy to figure out. Your +V should also be easy to trace. The output should be coming from the pot through a electrolytic capacitor... I don't think there's a line you need

Good afternoon, I have a couple of the Tait TB-9300 VHF repeaters for sale - currently they are set for Tier 3 DMR Trunking. These are complete units - reciter, 100w PA, and 48vdc to 24vdc power

Thank you Chris, At least now I know the frequency table of the CTCSS IC. I will know have to do some reverse engineering to figure-out what wire does what. Unless a member would know what

Hi to all, I just bought this ctcss board on a local hamfest but cant seam to find the documentation of it. I am hopping a member would reconnize the make and model. Thank you for looking. Best

I have been using Ooma Teleo for my landline for some time. You buy their ATA device and pay about $7 a month for taxes. It works well for outgoing DTMF. There may be some problems with incoming DTMF.

* Magic Jack is a VOIP ATA that uses a PC for the processing...the MJ is an external dongle * that provides the analog output to a RJ11...it is not a standalone ATA iirc..one local radio * station
