The Alinco DR-135T (non tnc version) has all the needed signals on a 
single 9 pin Dsub connector on the back.  The pins provide Squelch (open 
collector output), Audio out (independent of the volume control), Audio 
in, Ground, PTT (open collector output) and 5 volts at 50 ma power.  The 
5 volt power output is insufficient to power much, I do not use it.

I have been using the DR-135T with a TinyTrac for about a year.

I did connect a MFJ1270C to that same connector as a test and it worked 
just fine.

The only obvious problem with this radio is that if you leave the 
microphone plugged in it will introduce ambient noise into your 
transmitted signal.  So I run with the mic unplugged, although unless I 
have 'tunes' on real loud it doesn't seem to be an issue.

>Since Yaesu stopped producing the FT-1500, is there any VHF transceiver of choice with a data connector for APRS use these days? I know some of the dual-band rigs have a data port, but is anyone making a VHF only rig with a data port these days? I bought a used FT-1500 about a year or so back, followed by a new one, and later a bunch of new & used ones off eBay. They are hard to find these days.
