Or do I need a receiver with a true GPS trained reference input? I see only one cheaper price end RX with such a port, the SDRPlay RSP2, but that expects a 24 MHz reference input rather than the common 10 MHz. I have a Trimble Thunderbolt for a 10 MHz reference, but nothing that could give 24 MHz. What commercial SDR's could I look to for suitable stability please, that are good on LF and below, and a reasonable cost? Thanks 2E0ILY -- Best regards, Chris mailto:dead.fets@gmail.com
