Hi MF, Last night i've been at home while transmitting on the indoor loop again. The TX power was doubled, i.e. about 2 mW ERP, based on Rik's convincing calculation/estimation. The temperature depen
Hi I Still recommend hi value S/Mica crimped.Voltage ability very good too. They do not heat noticeably so remain stable. I found a large box of multiple values and mixed as required. Used at 137 als
Hi Stefan, In my experience these polypropylene capacitors when they fail, they just lose some capacitance. I think they call it 'self healing', maybe they imply that when they fail there is no short
Hi Thinking aloud, it is reasonable that the 6.8 nf capacitor heats more than the 2.2 nf since its impedance will be approximately 1/3 of the 2.2 nf one and when subjected to the same voltage will pa
...indeed! Since more than 72 hours i'm running the WSPR transmission in 25% duty cycle (each 8 minutes). First i tuned to 20 A antenna current and the temperature / antenna current changes were much
A little snapshot from the DL0AO LF/MF-grabber... 73, Markus --Ursprüngliche Mitteilung-- Von: DK7FC <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: So, 3. Feb.
Hi Markus, What a surprise, many thanks :-) This was just a short test. I just transmitted my call 4 times without an announcement and you picked it up. Very attentive :-) I never thought that someon
