[Milsurplus] H-250/251/etc?

[eugene at hertzmail.com]

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
