[Boatanchors] Station Set up follow up questions

[Mike Clarson]

Eugene: Be careful putting DC on an AC relay. Often, on AC, the inductance
of the coil keeps the coil from drawing too much current. Typically (and
your case may be different) a 120 volt DC relay would have a coil resistance
of 4000 Ohms, while the same relay designed for 120 VAC would have a coil
resistance of only 400 ohms. If you are going to try DC, keep the voltage
low (12V would be a good start)and make sure the relay coil does not draw
more current than it can handle. Good Luck.--Mike. WV2ZOW

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
