We are constructing the new controller
for our 1292.3 machine. A new idea was hatched today (6/7/02). We
are interested in improving
We have several people who use talkies around their houses-
and mobile- We are still trying to work out a co-existence scheme with our new neighbors, the Travis county police trunking system. Hopefully, we will have a breakthrough soon. ----------------------------------------------------------------------
July 03'- Update: We have implemented stage one of the
upgrade and have increased RX sensitivity by 6DB! We separated the RX and TX
antennas and installed a homebrew 6DB gain collinear antenna- 30 ft. higher than
the RX antenna. Second stage will be adding a second preamp at the RX antenna.
Computer model analysis shows that we could stand a little more gain right
there. TX will be sub-standard until we can get a better TX antenna installed.
Remember, RX is about twice as good as TX right now. So, however you hear the
repeater, you are getting into it about twice as good (using a 10 watt mobile
rig). You can expect to hit the machine FB using 100mw anywhere in the bowl of
Austin. |
