An older, direct replacement for the NLD 8773A was the NLD 8122A, which is the number yours replaced.
The low power module that covers 146-174 Mhz. is: NLD 8133A
The other modules are as follows.......................
1. NLD8121A: 136-151 Mhz.
2. NLD8122A(NLD8773A): 146-162 Mhz.
3. NLD8123A:157-174 Mhz.
Aside from the low power module previously mentioned, the remainder of those listed are all high power modules, along with their respective bandwidths.
Here's a listing of the pinouts or the PA modules.
1. RF Input
3. Voltage Control (Low/High, 2.5-7.0 VDC Transmit)(0Volts in RX)
6. B+
7. Base Bias (7.0 Volts transmit)
11. Temp. Sense(2.8 Volts transmit)
12. B+
13. RF Output
