Today’s success: one direction of a Hayward/Kopski bi-directional termination insensitive amplifier. I used KSP10 VHF transistors and it’s delivering more gain than expected (30dB!) rather than 20dB from 2n3904. Careful construction, so no oscillation. I’ll just put it into a pad rather than re-biasing. But it worked first try, again. Lucky weekend ☘️ I’m calling this mixed Manhattan/Ugly style “ugly man” haha

@relistan very cool! I aspire to giving a project like this a try someday soon.

@relistan Nice! Frequency? How are you determining there is no oscillation? (Did you get a scope or just using SA?) TNX & 73

@relistan Very nicely constructed! I always appreciate this sort of style and that's a fine result.
