[aprssig] Need EPROM Burned

Thanks for the info, Steve.
I've had so many different TNC's I can't keep
Them all straight. Do you know what the earliest
Firmware version is that includes Pactor support?
I also was unfortunate to run out and plop down $400
For a DSP232 when it came out, only to find out that 90%
Of its features didn't work and AEA/TW only supports
Packet, all else they abandoned. ARGH.
But I've had a hoot with my PK-900 which has a Pactor-
Packet gateway, which I ran for a few years. And I use
It sometimes to access WinLink.
Too bad not more TNC's include Pactor support.
Even if it's only Pactor-1.

The PK-232 is NOT a TAPR TNC2 clone.
It CANNOT run the various firmware alternatives like TheNet or UIdigi
used on TNC2 clones (such as the MFJ-127x series, PacCom units or even
Further, the '232 is a power hog, consuming over an amp at 12 VDC
compared to 200-300 mA for a TNC2 clone.
Finally, there is no explicit support for APRS in the PK-232 firmware.
It will not do call-sign-substituting decrementing-N digipeating
stand-alone. You have to run it in KISS mode with a program on a
computer to do modern WIDEn-N digipeating. By itself, it is only
useable as a basic WIDE1-1 home fill-in digipeater.
It is far more valuable as an HF device for RTTY, AMTOR and especially
PacTOR (for Winlink/Airmail) than for VHF APRS due to it's excellent 300
baud HF filters and modem. With recent firmware that supports PacTOR,
they should be an easy sell to the boating/yachting types that are
always looking for WinLink appliances.
