 RADIOHF - Panadapter for ICOM IC-7300  
Panadapter board for ICOM IC-7300. This is the HRO model and it worked perfectly before I removed it from my IC-7300 before I sold it. Just add an external receiver and you can have a panadapter on your computer using HDSDR free software to see the signals on the band with point-and-click. I am asking $150 shipped and PayPal is fine for payment.

 RADIOVHF - Radio use monthly fee
Is this the future of ham radio. Buying a radio and having to pay a monthly charge to use its SDR software system like the Rfinder B1. As I shopped and researched the Rfinder I was surprise about the monthly subscription fee for the digital software side of this radio. Call me cheap but I was not impressed. It’s most likely hams are dumping these radios now on the used radio market but still is this the direction manufacturers are going in the future. Robert K9TWC Robert 715-501-0606
