Does anyone have any experience with the Icom 7610 on AM? Is it's transmit limited to 6 KHz like the 7300 or is the transmit bandwidth adjustable via menu to more than 6 KHz??

Hello Rich,

I took a look through the manual and the options and layout seem very similar to the IC-7300. The widest transmit bandwidth on SSB seems to be the same at 100-2900hz which leads me to believe the AM bandwidth is the same as the IC-7300. There are reports that receive audio on AM is better than the IC-7300 which rolled off everything below 200hz but I have not listened to an IC-7610 to confirm this.

On the 7610, AM rolls off abruptly at 300 hz unlike the 7300 which does so at 150 hz.
AM sounds better on the 7300 Embarrassed Embarrassed Cry
I can find nothing in the hidden menu to correct this.
Feeding AF into the ACC input has the same result.
