Here's a collection of random useful knowledge in regards to Harris/Macom/Ericcson equipment.

XL-75P/XG-100P/XL-200P DIY Programming Cable

The cable is fairly simply electrically. Consists of 4 USB pins (GND, PWR, D-, D+) and a 6.8k resistor between pin 3 and ground.

P/M7100 Firmware Upgrading

If you're encountering issues with loading new BIN/DSP files onto the P7100/M7100 radios, it's important to use a computer with a hardware serial port. Many issues with writing firmware can be attributed to improper timing/control of USB to serial adapters. FTDI adapters, while good for most purposes, also exhibit this issue. If you get errors such as "Fail Write Radio Code", try a hardware serial port.
