[MRCA] HF-80 video

[W2HX]

Very nice! I have that receiver along with a 1KW transmitter setup. My plan, however, is to replace the receiver with an 851S-1 I bought. That way you get the VFO. I like to have a VFO on my receivers (at least). Find a station and then punch that into the transmitter (if controlled separately).

Latest video, this one is on the Collins HF-80 receiver, big box with lots of engineering. Maybe Collins idea as a answer to a SSB/ISB version of R-390? Can run up to four channels of side band at once. Also they did lock everything to a common reference so far better in terms of phase noise and stability to any of there tube products. Thinner then the R-390 but longer and appears to be almost as heavy! And just like the R-390 or 390A still a chore to tune.
