[RTTY] MMTTY VS PK-232

[Joe <k0bx@qsl.net>]

This has been a very good topic.  I must say that MMTTY copies better 
than my PK-232MBX but the '232' served me well for many years.  Mostly 
the MMTTY does a better job of copying very weak audio rtty where the 
PK-232 would not even hear.  I even added a one stage preamp to my 
PK-232 to raise the fixed audio level from the TS-850S.  Still the 
PK-232 is a good terminal unit.

I have a detail article on my website on how to sharpen the filters for 
170 HZ shift and realign the PK-232 for 170 HZ shift.  The stock PK-232 
is setup for 200hz shift so it could be used for Packet and rtty.

The article is at:

I believe AA5AU used the PK-232 until MMTTY came out(?).

Anyway, anyone with the PK-232 should find this article helpful.
