[Boatanchors] Station Set up follow up questions

[Eugene Hertz]

Hi Rod and boatanchor enthusiasts:

I have played around with the actuator arm of the TR relay and I seem to have reduced the hum to a pretty tolerable level. I might try the rectifier anyway just for giggle.

As for the talking on frequency, it seems the 100V has this capability! I simply had to RTFM.  There is a front panel switch that will output a low power carrier and not key the TR relay. This seems to work pretty well! I will also allow you to talk into the mic and also not key the relay with very low power output. I have tried this and it seems very usable (albeit slow, but thats to be expected with 1960's gear, I guess!)

Thanks to EVERYONE with all the suggestions
Eugene
