I posted a reply yesterday, but it didn't go through so here it is again. I wanted to say thanks to everyone who took the time to give helpful advice and send me the revised .ADA file by Bert Keizer. Bert himself even PMed me with the file. It is indeed cross-platform (I'm on a Mac) and it works like a charm on my machine. Fantastic job Bert!! Your added "Tune" feature is a lifesaver for me since the MKS-80 that I found on Ebay has a broken Auto Tune button. I can trigger oscillator tuning by turning the unit off and on again, but that gets old fast plus I have to be physically near enough to the MKS-80 to reach the power button. Thanks again everyone. This is a great forum/group! Aloha From Hawaii. Mitch
