Hi Eugene:

The U-229 style audio accessories are general in nature and not specific to one 
radio.  See a photo gallery of some common U-229, U-77 and older audio 
accessories at: http://www.prc68.com/I/MAA.shtml

See the Audio pin out info for the U-229 type connector at:
http://www.prc68.com/I/U229PO.shtml#A
Pin E is for CW, so yes you can have a key, mike and cans all at the same time.

Unfortunately the U-229/U Y-cable does not have all the pins duplicated and so 
will NOT work with your HF radio.  A custom cable is needed.  I've thought 
about making custom U-229 cables let me know if you're interested.

Have Fun,

Hi All, this is my first post here.

Just picked up a neat little hf backpack radio, a southcom SC120D. I hope to 
use this camping next month.

The unit uses an H-250 mic/earphone combo.  I was wondering if there was ever a 
headphone/mic combo made for this? I know there is an H-251 headphones, but is 
there a model with cans and a mic?

Also, if I wanted to get a second person listening in, I have heard there is a 
"Y" cable that could possible be used. Anyone know what the designation for 
that might be?

Lastly, the connector used for the H-250 is also used for a cw key. Anyone know 
if there was ever a way to get headphones, mic and key all connected up at the 
same time?

Thanks
