G'day, | There is a neat way to check whether you are going to experience a dangerous | amount of RF pickup. If you can find a Radio Shack that still has and can | find hobbyist parts, look for their "grain of wheat" miniature incandescent | bulbs. They have some that are rated at 6v/25ma etc, but you want the one | rated at 1.5V/25ma. Solder it to a coax connector and screw it into an | unoccupied port on your switch. Crank up your tx/amp to the max power you | are going to use and key the TX. Watch the bulb. If you see nothing from | the lamp, you are ok. If you see a dull glow, be worried about just how | consistent your switch is (I have an Alpha Delta--which I use now only for | beverage switching) which shows variable performance, the reason for which | is apparent if you open it up and look at the guts).
The Yaesu FT-101 had a lamp in series with the RX side of the TX/RX change over relay. When I was in the Antarctic ('74 - '76) and running traffic on the main station (1.5kW) it was not unusual to see the lamp flashing along with the CW or SSB if I left the antenna on the '101. Never hurt it. Regards, Mike VP8NO _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
