Bob,

I recommend you look at the Yaesu FTM-6000 as an alternative choice, considering currently available radios.? This radio has a dedicated data port and is 100% VARA FM Wide capable and when paired with the appropriate DRA and cable, you can work any normal Winlink mode as fast as it gets.? Considering this is a dual-band radio, the value is on par with the Alinco DR-X35 series radios, which are commonly selling for $250 + on the used market.? It also doesn't have the spurious emission issue that you reported on with later MKIII Alinco's.

Many of the Yaesu FTM radios require a proprietary Mini-DIN-10 cable or CT-164 adapter to connect the sound card interface to their data port.? I have a custom pre-made MD10 male to MD6 male cable that works on any Mini-DIN-10 equipped FTM Series mobile radio.? It's called the .? The FTM-6000 radio pairs well with a DRA-50 or DRA-50M, and provides for the fastest possible VARA FM Wide speeds.

I have no affiliation with Yaesu - I'm simply a satisfied customer.

Thanks for the clarification.? For now, I’ll keep looking for used Alinco DR-135 series radios for Winlink VARA FM WIDE.? Hopefully more manufacturers will recognize the need and began to offer radios with a proper audio data connection.

Bob,

Stephen is correct.? There are several companies, including Masters Communications, that makes an for the TYT TH-9000D radio.? However - unlike the Alinco DR-X35, the TYT TH-9000D is NOT wide band capable.? It only has filtered audio available at the plug on the motherboard - IE "1200 Baud" type of audio.

I additionally sell .? This allows an to be used between the radio and MD6 equipped radio interface like a DRA-36M.? Because the TYT TH-9000 is only narrow band capable - all baud rate jumpers need to be set to the "1200" position, as 9600 is not a valid choice.

So regardless of the radio interface you choose - your throughput is going to be narrow.

The case is identical to the Alinco DR-135 and has the cut out for the DB9 on the back.? Repeater Builder sells a DB9 cable assembly ?that plugs into a connector on the motherboard providing unfiltered audio.? Others have written about using this for 9600 baud.? So far, I found that the receive audio is a bit too low for the RIM Alinco 9600 adapter. ? I may try a Master Comm adapter as it has adjustable gain.

I have been investigating the TYT TH-9000D Plus as a possible low-cost alternative to the now obsolete Alinco DR-135 series for Winlink VARA FM WIDE.??

Regardless of spurs, this radio will NEVER work on VARA-FM WIDE.? It lacks the "data port" (actually wide-band audio audio from the receiver discriminator on RX and direct access to the transmitter modulator on TX.?? (You can't use mic/speaker connections on VARA-FM WIDE.)

The lack of the data port (usually a 6-pin minid-DIN jack)? is a chronic "missing feature" on Chinese radios, except for those made by HYS.
