Info wanted on animal transmitter seeking equipment??
I've tried doing a google search but came up with nothing.
I noticed on TV when tracking animals with TX collars they hold the 3 element beam behind the reflector. Seems that this would be a problem. I have a HT that I want to DF with.... How and where would I connect an analog S-meter like I've seen on TV. |

Thatcher,
Some receivers have a jack that makes the AGC voltage available, if your has that a sensitive voltmeter could be used there. If tracking on 2 meters, there is some advantage to monitoring the third harmonic on the 440 band, or use a local oscillator-mixer technique to offset the frequency you monitor to minimize the likelihood of over powering the receiver. Alan Broadband company makes a device they call "Zap Checker" Used by some for tracking. You might look at www.zapchecker.com see if you could use it. I have a model 180 that has both linear and log response. Why would holding the antenna behind the reflector pose a problem? I think most doing animal tracking know little about RF and are not using the equipment they have to their best advantage. Also possibly using the wrong frequency for the application. I have talked to some Federal Rangers about the animal tracking they do and they have little time to learn the best techniques and possibly little incentive to learn and apply. I hope you are successful in your tracking. Best wishes from ray "thatcher" wrote in message ... I've tried doing a google search but came up with nothing.
