73 ஆசீர்வாதம் என்பது என்ன வ

加加減減

加加減減 The usage of "73" for such a purpose comes from the phillips code, originally devised in the era of telegraphs to speed up transmission of common messages by mapping them to numbers. "73" mapped to "best regards" or "my compliments" and was intended as a general valediction for transmitted messages. it is still used for that purpose today in morse code transmissions and often makes its way. I am learning about amateur radio so as i can go for my foundation licence but i was on cb back in the days, a channel nine monitor and used the 10 code and the q code but all i can see is the 73.

Since it is "technically" a complete qso i log it (in dxkeeper) but don't upload to e qsl or lotw unless the other party does. if he does, i'll upload: if he doesn't i assume he has it as incomplete. i think this saves a lot of time later, looking up the qso details in the .txt log! some folks simply don't bother with "73". 73 dave k1dje. I am following 50ohm matching until balun and after that 73 ohm everywhere. just looking at the two branches of your antenna: i'm not sure i'd say you're "violating" anything, but the model for a "simple" dipole is that the gap between the conductors is zero (or at least very small compared to wavelength). I'm new to cw and one thing i couldn't figure out is when i supposed to send "e e". let's say i'm calling cq and somebody answers me. the qso is almost over. should it be ended like this: tnx fe. For example, fair rite's 73 material: what's a $\mu' s$ and a $\mu'' s$? what do these numbers represent, and how can i use them in amateur radio? do they allow me to predict inductance or losses of inductors made on cores of this material? what is the relevant math?.

Theoretically, (73 j42.5)Ω. when the dipole is too short, its reactance will be capacitive. when it's too long, inductive. since the exactly half wave dipole has a slightly inductive reactance, shortening it can eliminate the reactance. the exact amount of shortening depends on the thickness of the wire. 0.41λ sounds like a reasonable estimate. The best thing to do is to listen for a while, and notice which stations are being responded to. sometime operators will prematurely respond with their callsign, without waiting to hear if the other station has finished broadcasting. it's about %80 timing and %20 luck! and, as always, good luck and 73!. An ideal dipole, at resonance, will have an impedance around 73 ohms. a folded dipole, around 280 ohms. how can i calculate the impedances when not at resonance? let's assume i have a span of 15m. A physically half wave dipole isn't resonant. as you say, it has an impedance around 73 j43 ohms. since the reactance is non zero, it is by definition not resonant. any manner of matching devices could be added to the antenna, and considered as a whole, they would make a resonant system. but that's not what people usually mean when they say "resonant antenna". instead, the antenna can be made.
