K3 Scan question

Mike K2MK
I've been using the SCAN feature on 10 meters trying to give out some field day points to the non air conditioned guys. If you just hold SCAN the audio turns off as the scanning begins. If you hold SCAN extra long the audio returns after a bit. Since the audio is on when I first hold the SCAN button wouldn't it make more sense for the audio to remain on when I hold SCAN and for the audio to fade out if I long-hold SCAN. Is this some sort of established standard for scan implementation.

Hi Mike,

This is just a side effect of the implementation. "Normal" scan  
(started with a regular-length hold) mutes until a signal appears  
that's above the scan threshold. "Live" scan (started by a long hold)  
holds the audio open at all times, and never stops sweeping the VFO.

Hi Wayne,

Thanks for the explanation. I guess I didn't remember that there were actually 2 different types of scans. I was using the long hold as a way to listen while it scanned. But you are right, with a long hold it would run right by any signal unless it is stopped manually with a key press or a paddle press (in CW mode).
