Re: MFJ Dropping out of KISS mode...

JKISS is a KISS only EPROM image from G8BPQ version 4.08 that has been around for at least 20 years that will convert an MFJ or any TNC2 clone into a KISS only system. We used this on a BBS system in the early 1990's and we used this on an IGate around early 2000 to eliminate the problem of dropping out of KISS mode. The JKISS image made it rock solid. A MFJ TNC220 will require the 220KISS image which is a variant of JKISS.

You can get the EPROM image from BPQ v4.08 and burn your own EPROM.

unfortunately, no.

when we ran mfj tncs for the bbs that needed the mfj to be in kiss mode, we
had to replace the eeprom with a kiss only one, that was aftermarket and i
have no idea where to get them now. besides, i think they cost about the
same as a tt4 or otusb if you could find them now.

I had what I needed to see right here. At 15:45:12 UTC, your TNC
rebooted itself and dropped out of KISS mode. It was working fine until
out of the blue it reported "RAM loaded with defaults...." and started
sending raw ASCII packets instead of KISS packets which causes APRSIS32
to complain about the missing C0 that's supposed to be at the beginning
of every KISS packet.

Is there a configuration setting to have the MFJ power up in KISS mode?
Or do you have any idea why it reset itself to start with?
