I guess this is as good a place as any, to add this info.
Belonging to the Yahoo 7300 Group, I recently read that INRAD has announced a 2nd receiver adapter for the 7300.
One of the 'complaints' of this radio is the fact it has only one antenna connector. Since I cannot imagine anyone needing an additional, outboard preamp for HF, it 'appears' this device was intended for a Beverage or similar antenna. Maybe Diversity reception?
(don't you find the complaints that "the radio is TOO sensitive!", bizarre? Have hams forgotten how to use a RF Gain control?)
(also the folks that buy the 7300 and give negative reviews because it has only ONE antenna connector. Didn't they read that B4 buying? I did!)
Anyway, I thought about it and since it replaces the Molex connector for my LDG IT-100 and would require additional relay switching, I'll pass. I currently use manual switching for HF/6M anyway. No big deal.
The 7610 will have multiple antenna connections.
