CTCSS decoding


 

I am a novice with the DINAH? interface.? I have it working with a used radio that I picked up cheap, an Icom IC-207H.? When I bought this radio I wasn't aware that it did not have the capability of using CTCSS for receiver squelch control.? I don't want to run my Allstar node without CTCSS, so is there any other option short of buying another radio?

I am going to Dayton so I could look for another radio there.? Does anyone have a recommendation for a radio with the 6 pin din connector and CTCSS for recieve?

Hi:

Two radios I can think of off the top of my head, and I'm sure there are others, may be overkill:

The Kenwood TM-V71A has the option to chain COS for the data port to squelch in one of it's menus, as does the Yaesu FTM-100, and probably the 300 and 400 as well, though you'll need to convert it's 10-pin DIN to a 6-pin.

I have an old Kenwood TM-D700A that doesn't. Regardless of the state of CTCSS/DCS decoding, COS is always opened by a carrier, and there is no way to change that without modifying the radio. The effect is that, if you key up on the frequency the radio is receiving on without the correct tone, it sends COS to the node, but no audio.

Hi Patrick, I deliberately did not mention the Ftm series because he specified 6 pin din.?

The 207H has a 6 pin mini din on the back of it.

That is what I am finding with the IC-207H.? I found that is does have CTCSS for receive but COS is send to the node even though CTCSS is enable for received.? I would prefer not to key up all of the link repeaters when some one keys up on my Allstar node.
