Not a problem on spelling especially if tired. The problem you are running into is really curious indeed. Since we have no LORAN C in N A anymore. I can only use the loran simulator to drive the FS700 and that works very well. I have the antenuator in the simulator at -55 db as I recall to simulate the signal I used to get from the 9960 chain. Literally have no problem at all as you have run into. I did put the eproms on the K04bb site for safe keeping. Maybe software vintage? Regards
