It's KHz. The international convention is that you use an upper-case letter for multipliers that are greater than one, and lower-case for multipliers smaller than one. This helps distinguish, for example, between the abbreviations M for the Mega prefix (multiply by a million, greater than one) and m for the milli prefix (multiply by 1/1000, less than one). Similarly P for Peta (a quadrillion) and p for pico (a trillionth); D for Deka (10) and d for deci (1/10). There are other such pairs (Yotta and yocto, Zetta and zepto), but we don't see them much in Amateur Radio.

For prefixes like Kilo this is not universally followed (no smaller-than-one prefix starts with k), and some authorities say the convention doesn't actually exist and the short form for kilo is k. Pooh.

Carl,

I knew I could count on you for the correct info!

I had enough trouble converting from Cycles to Hertz a few years ago.

Thanks.

You do understand that a careful reading of my post leads to the (correct) conclusion that I'm uncertain, right?

Default Interesting project

Hi Dick. I will be very interested in hearing about your tests with the TH antenna. Was it a model 100 or what model?
I have had a 100 mounted on the ladder of my fiver since we've been in the "temporary" park (last June) we're in and to tell you the truth it has worked great. Rarely is there a station I hear that hasn't come back to me. I'm running about 400-500 watts with an ALS-600 to the TH and I know that helps but I am genuinely surprised at the performance. I have made no attempt at grounding or radials, etc. It just is mounted to the top of the ladder.
I will be retiring in a month (YEA!) then it's off to the permanent location in a RV resort in FL and I will try the exact same approach there but I also want to test the TH mounted over the top of an 8 foot square metal shed that is located on each lot. Robert at TH said it should work great. I will bond the mount to the shed and see what improvement may be had. I will keep you posted...please do the same with your project. I will appreciate hearing what you may discover.
73, Bill

Default Cycles/Hertz Conversion

Oh BTW Dick. I had the same problem ever since I've misplaced my slide rule.
However, I found out that there is an app for that too.

Naah. I don't think Hertz rents cycles anyhow.

Carl,

I don't know how you come up with those lines, hilarious!!!! Keep them coming.

Bill,
I will keep you posted on progress. We are supposed to be back on the road in June, will have update sometime in June probably.
Congrats on your retirement!!

See new post for next technical question that will undoubtedly generate smoke and heat and just perhaps some light! :-)
