Barrett 910 Autotune Antenna
The Barrett 910 Auto Tune antenna is currently mounted on the rear of the Pajero, and is being driven by the Barrett 950 HF radio. The antenna has a receive preamp to boost the incoming signal when the antenna is not tuned (eg scanning). This is turned off when the transmit key is pressed.
I am currently trying to get the 910 antenna to work on my FT-897D. I have disabled the receive pre-amp, and when I transmit, it tries to tune once, but doesn't get a low SWR. To retune, I need to power the antenna off and on (or enable then disable the preamp).
If anyone has experience with driving this antenna, I would appreciate some help. (contact me via guestbook)
