For the sake of completeness, it should be stressed that pushing any RF current into the soil should be avoided as much as possible. That would be a pure waste of energy on transmission, and a source

Yes, I can see them on pp. 8-10 of EPR, but what makes you think they are DSP-generated? Well, a very small number of hams is aware that their receivers have serious limits, let alone how low the li

Well, formally that's correct, but for ages it has been customary to indicate number of poles according to the equivalent low-pass filter. For bandpass filters this means 4 crystals = 4 "poles". Inr

Such a thing would be possible only on a very bad receiver. I don't own the Jupiter, but I doubt that it could be that bad. Or perhaps you did confuse sensitivity with gain. 73, Sinisa YT1NT, VA3TTN

Looks like you're right! The keying waveform itself has a duty cycle slightly offset to 52 %, and it produces RF duty cycle of only 30 % (22 % for the first dit). Shortening seems to be 8.8 ms (12 ms

Not really, the key is closed when upper trace is low, therefore RF is delayed ~21 ms for the first dit, and ~16 ms for the second. 73, Sinisa Yt1NT, VA3TTN __________________________________________

Equipment manufacturers are not required to provide facilities for shortening or lengthening of dits. It would suffice if they simply and accurately reproduced what is being supplied. 73, Sinisa YT1N

If fact, both elements ARE affected. Shortening seems to be 8.8 ms (12 ms for the first dit). (Dit width measured at half amplitude). 73, Sinisa YT1NT, VA3TTN ________________________________________

I find this inferior to PTT because of extra delay. Using PTT I'm on receive immediately after the last dit ends, and all that with a non-QSK amplifier. I believe that manufacturers should limit them

Yes, that would be imperceptible. But, as it isn't, it ain't. The first dit is shortened by 12 ms, and rest by 8.8 ms. 73, Sinisa YT1NT, VA3TTN _______________________________________________ TenTec

Input keying waveform is usually put through two kinds of circuits before being actually used. It goes through a low pass filter (RC), and filter's output gets shaped by a Schmitt trigger. Depending
