"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.

For example, fair rite's 73 material: what's a μ′s μ s and a μ′′s μ 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?. 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. 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.

It is interesting to have swl reports because i was a swl when i was a kid in the 50's and receiving distant stations was very interesting, bbc, voa, radio south africa rsa, hcjb of course and the biggest bommer on the band, rado moscow. i am glad for the interest in swl. 73. kdØqg. The mnzn ferrite cores (mix 31, 73, 75) have high permeabilities above 800 µ, have fairly low volume resistivity and moderate saturation flux density. they offer high ‘q’ factors for the 1 khz to 1 mhz frequency range. In the end, we have 73, which is commonly used. then there's the procedural part. i send sk, meaning that i'm ending the conversation and i send cl, meaning that i'm closing down my station. the other side will provide a similar transmission. sometimes, at the very end, people will send e e and e after the final official relation. Model the 1 2 wave center fed antenna using the wire size, altitude, and all location attributes to determine the center fed impedance. divide 600 by the 73 ohms or whatever you calculate the center fed impedance to be then multiply the answer by 600 you're home. example: 600 73 = 8.22 × 600 = 4900 600 73 = 8.22 × 600 = 4900 ohms. this is the original and correct quarter wave transform.
