Hi Paul & Harold Thanks for your comments. I had a 30dB fixed attenuator on the output of the LNA, & a switchable attenuator (Hatfield 2105, 0-100dB in 1dB...

Dima, If there is an extra one because I have made a duplicate entry, then I will reserve that oscillator for you. Apparently I have mistaken Richard for two...
Been meaning to write this testimonial for a long time. It's about time I did so. I've built several VNA's to date and all are wonderful pieces of test ...
Hi Harold, Here I am at the other end of construction of this project, as it were, compared to you. I drilled and cut the case for my VNA only this afternoon...
... Oh no it's not Len! My original 10-12 meter STAR LP TX filter was 3 dB IL on 12 and 4 dB on 10, with a 7 dB droop around 27 MHz. I wasn't planning on using...
