I did the mod according to the sketch you mentioned, which I happened to see stuck inside the manual when I bought the old HT37. It didn't work for me, so I took it out, So far I haven't been able to find a way to use the HT 37 on CW without wearing out the front panel switch.? It works great on CW, but the manual switching regularly will wear the switch out plus it's a lot of trouble.? I would love to use it on CW but cannot find an easy way.
