Private Note to my QRM Station

Post author By admin
Post date October 22, 2023

We have had three stations that QRM me. We have used KiwiSDR to track down two of them. This station is the newer one and we are close to tracking him down too.. I would prefer that we didn’t have to try. Anyway, I say it all in the video. I’m not angry, I just want to understand him and help him out. PS – When I say "we", I refer to an Army of volunteer folks and local clubs who help me out with the DF problem and intelligence. Thanks. Callum.

If you DON’T use the Standard Phonetic Spelling Alphabet

Post author By admin
Post date October 21, 2023

Sometimes I quite like non-standard phonetics, for instance "Suga-Papa" (Poland) and "George Four XYZ" for an older UK callsign, it’s important we recognise when and when NOT to deviate from the standards. See what you think anyway. I know this isn’t set in stone, but this video is for just some guidance that newbies might find helpful. If you follow the "rules" I find that it also helps me when I’m "in the chair" running a pile-up. Callum.

Link: Here’s the "official" one that seems to work for me. You might know of a better one: https://en.wikipedia.org/wiki/NATO_phonetic_alphabet

Have we lost the art of real listening because we rely on technology instead of our ears? I have an idea. Callum.

What is a Coax Phasing Line?

Post author By admin
Post date October 15, 2023

In the main, we use phase lines to split power to more than one antenna. By selecting the right lengths of delay / phase lines, we can skew our energy towards our target. Let me explain.
And here’s the calculator link: https://www.va7st.ca/christman.htm

I get that you are low-power, but stop asking me for the sympathy vote. I have a HUGE respect for folks who get through with their regular call.. But I still need your callsign! What do you say? Callum.

Coax Velocity Factor – Is it Important?

Post author By admin
Post date October 13, 2023

Do we need to know or even understand the velocity factor of a coax line? In the main, no – although very often, velocity factor often follows loss – but that is not the point today. You shouldn’t (normally) have to worry about coax velocity factor. Let me explain. Callum.
