Alinco DX-SR8T: Expanding the Transmit & Receive Ranges
Bottom of the rig:
If you're wondering what those jumper pads are for - they are for modifying stock parameters of the system. Jumpering pad A changes the receive range from 135kHz - 29.99999MHz to 30kHz - 34.99999MHz and jumpering pad B changes the transmit range to 1.6MHz - 29.99999MHz. I'm not sure what the D pad does. I can't find my notes from that. I always "open up" rigs when I can - not to operate illegally, but just to have as much function as is possible: e.g., using the rig as a signal generator into a dummy load for testing another radio.
