[GreenKeys] Northern radio TU type 174 model 1 and RTTY questions

[wa2hwj at att.net]

John,

I have a Northern Radio 174 also. And, I have the manual, somewhere.
Contact me over the weekend and I'll dig out the manual and
give you the hookup info. I have not yet had a chance to
get my 174 going...it needs a little work.

73,

Jack K0TTY
