Hello dear Michael,

Thank You for answering me back, really appreciated.

Last  5 or 7 years I'm searching crazyly for good VHF/UHF Receiver, which was needed strongly for some of my experiments...
Tryed from R-375 russuan reconnaisance, valve receiver (ceramic triods, cascade amplifier configuration in Front End and cavity, coaxial resonators...) Made in early 60s
and was top secret very long time..
.
To the WINRADIO G-305e SDR VHF/UHF receiver, modern one from Australia.  Tuning knob virtual there on computer screen...Endless configuration, variations available there, good one, but if you know great feeling when you keep World of signals on tip of you fingers you feel nothing with that computer screen, virtual tuning knob...(impotent radio...)

Result very simple-that expensive, modern toy lay down somewhere in may room and i'm forget already when i touch it last time...Lack of interest.
That equipment for those who never touch controls of classic professional rigs...that for sure. For young, new generation people...

By the way, in the end i find Watkins-Johson VHF/UHF Receiver WJ-8618A in glorious condition and really happy with that Radio!
For example VHF Band Preamplifier Board there almost all,  about  95 percent resistors is type RN55C Spec. MIlitary standard resistors with very low noise level and endless life lasting!...
You will never find this approach in any amateur equipment...That is totally different world...

Thanks for You Michael and all other's who involved in this interested discussion...
Best Regards,
73s

P.S.

I'm looking for those who owner of WJ-8616, 17, 18 series recivers with A version, not B
1st Local Oscillator there very interested design, accordance with some information not stable and noisy. But in my own nothing wrong...Doing very well. That is version "3" board
there...For other discussion about 1st LO of that Radio...If any one interested pls welcome to my E-mail. Thanks.
