[amsat-bb] Accessory to add CTCSS tone?

[Todd W Deckard]

Greetings!   

Can a simple circuit or OTS accessory add the 67hz PL tone to a radio mixing w/ microphone in?

 I purchased an ICOM IC-X2 from ebay to get access to the L-band and my Japanese was pretty rusty and so I didn’t realize it appears the PL tone squelch was optional on non-US variants of the radio.

(At least I cannot seem to invoke it thru the menu navigation)

It’s an awesome little radio and was a great deal.   Is there any way I can build something to inject the 67hz myself?

Best
