The RF power amplifier IC, a 3-pin IC marked with "BLU86", is a Philips BLU86 running at 12 volts DC (1 Watt RF output). It's maximum possible RF power output is 1.5 Watts with a higher collector voltage (17 VDC max). It's best to leave this device at its current voltage.
There is also some BFG198s. Probably some sort of buffer amplifier and a driver.
This card is really old and confusing. It will proabably take a while to figure out.
Tap Points For Transmit/Receive
Pin 11 of the Daedalus ASIC appears to be +5 VDC on receive, 0 VDC on transmit. You may view the location here.
