Hal,
Thanks for the guidance for the proper use of "sans".
Further to my original question:
RJ1H relays have tungsten contacts used primarily
in hot switching applications. The contact resistance
is 30 mOhms and the current rating falls off much above
2.5 Mhz. Switching time is a scant 6 ms.
I can obtain new ones for relatively low price.
Are they suitable for Amateur Radio use at full legal power levels?
