What is the most economical relay switch to use for operating on battery power that would sustain battery life using a YAESU FT 857 and a 12V rechargeable battery? A low transmitting power is desired 0-15 watts. I looked at two different relays (see below) but not sure what to use and if these relays are compatible with the specifications of a FT-857. Relay#1) SPDT Electromechanical Relay Failsafe Switch DC to 26.5 GHz,SMA, 20 Watts, 12V Control, TTL, Diodes, Indicators ($129.56 - $169.15) Relay #2) SMA Female SPDT Relay Switch DC-3 GHz, 12 Vdc Bracke Part Number: BM14068 |

Those relays appear to be RF relays. Exactly what are you trying to switch? |

I use a lot of SMA relays on the microwave bands. There are lots of cheap relays that will work up to 6M--just check out homebrew remote switch articles. Zack W1VT ARRL Senior Lab Engineer |
