Yeah, I remember having to tune radios and antenna couplers....I am the proud owner of a Navy AN/URC-35 HF rig...you can see it on my old web page
http://www.enter.net/~k3mp I purchased that rig at the Dayton Hamfest in 1998 and it was overhauled by Navcomsta Ponce Puerto Rico in the late 80's...it works great, 2.999 Mcs to 29.999 Mcs ...I really never did like CW until I became a ham...we did more RTTY (FSK) on the ship than anything else.
