My transmitter has a total output of -30dBm. My receiver has a maximum sensitivity of -42dBm. My antenna is a 3 meter wire. Yesterday I got contacts with two JA1, one F3, one HK6, three RU1, two YO,

Reminiscent of the dark old days when I was a young & poor Radioamateur, and whenever a find myself with some extra cash in the pocket, I buy some second hand equipment and sent it back to my Old Cou
Hmmm.... "hot spots" .... Sounds like grade 9 physics :) Perhaps the correct utterance is that the windings gaps provide a redistribution of the inter-thread capacitance that can and will form an res
If your design constrains allow for a relatively high PS output internal resistance (5 - 100OHM) it will be wise to insert in SERIES with every capacitor a limiting resistor/fuse. A thyristor crossba
See, I do need a schematic to be able to give you a precise answer! If you are switching the Primary of a transformer and your fuses between the SSR and the transformer are blowing, I will suspect qu
Well, he probably followed your advice not to complicate the matters and as a minimalist that he is, he just had overdone it a bit :) A true KISS man :) Alex Big SNIP
According to you, my friend, we never should drive a 12 cylinder Jaguar as it is overly complicated, neither a YUGO as it is to simplistic. According to you we all must drive a DODGE as it fits YOUR
I hold in my hand, a BIG vacuum variable cap. Part number is N16-C-65863-2275. 10.000Volts. Some one scribbled with an Sharpie pen on it "Type UCS" On the visible internal cylinder there is engraved
YES! Now I see it .... very faint but it is there ... it says UCS 300... Now, if only I would know that that means ... before I dig out my capacitor meter :) Will call them tomorrow ... they must kno
