T500 Modifications
The club owns a Tait T535 and a Tait T520C. These are quite easy to modify for operation on amateur bands, so this is what shall be done.
One of the radios works on transmit. Channel 1 is 145.200 and channel 2 is a shade under 186.000. Receive is unconfirmed, calculations suggest weird frequencies in the 130 MHz range and the 190 MHz range. TODO: alter the solder bridges to shift RX to somewhere sensible and test.
T535
- Can be easily modified for 2m or 4m operation
- Channel 1 has been set to 145.350 MHz with the jumper settings below
- Channel 2?
These are the jumper settings for 145.350 MHz, as per http://www.davidmpye.com/?q=node/17
