After the spontaneous reset, the KISS params are reset to defaults. It might be possible to patch in new defaults, but I've never seen an addr table for the 1278. For the 1270, I'd recommend replacing the firmware with TAPR 1.1.7b (or 1.1.8a, which has the same KISS as 1.1.7b).

We can get the unit to work on cw, but not on rtty. The unit will tune but nothing comes up on our computer screen. We are using the cable supplied with the IBM software from MFJ, but it does not work... Any help would be appreciated...

I'm looking for a computer program (DOS, I guess, or Windows) called "Ham Windows" (?) by Kenwood. One of my friends in India, VU2IJ, wants to have this for his shack. It seems to be some kind of all- singing, all-dancing log + rotor control + keyer software. What does it really do? And, how much does it cost? Most importantly, is there any good public-domain equivalent for DOS/Windows available from any ftp site? Please help; reply directly to pdastoor@gumbo.age.lsu.edu. Thanks.

I believe it is done by sending a shift character to get between the character sets. It works QUITE well and covers all needed characters for written language (I.e. no IBMPC character graphics).

The KAM uses switched capacitive filters, and they appear to change bandwidths (and filter chips) when switching modes. The software also allows for selection of passband frequencies. The PK232 uses opamp-based filters, and the settings are adjustable by replacing sets of 4 resistors at a time... Neither of these produces a very good display on an attached monitor scope. I think the filters in both are poor. I'd like to see a scope output from a DSP-based terminal unit. Use of an outboard DSP unit appears to be a questionable practice for Amtor and possibly pactor due to the propagation delay. I hope I'm wrong about this (Bob M.?).
