To confuse the matter of toroids further, the catalogs I have show the iron
dust toroid T50-2 made by Micrometals as working in the mid to low HF, 0.25 -
10MHz range and identified by a red color.
The T50-6 seems the best for all round HF use with a listing of 2 - 30Mhz
and identified by a
I'm just posting this so that someone can tell me ... NO - DON'T DO THAT - or -
DO THIS.
I know I could use a loop inside of a compact loop, but a toroid is more
appealing for me because of the size and appearance. It looks like the
consensus is that I need an Iron Core Toroid ... something along
I've found a trick to locate top-side parts in K2 Appendix F that are
labeled but not findable in Adobe Reader (formerly called Acrobat Reader).
It turns out that the unsearchable parts are the ones that are labeled
vertically (i.e., bottom to top).
The searchable top-side parts have labels

Well Dan,
A F-114-43 should work ok for a transformer. I don't know of any design
data. When I said the iron core was for tuned circuits, I meant a coil and
condenser type. The ferrite cores are better for broadband transformers.

The original PSK31 implementation included an option for FSK31.
Theoretically, PSK31 should provide a 2-3 dB improvement in signal to noise
ratio over FSK31. In practice, it is necessary to back off the power
amplifier by a few dB to keep from generating an excessively wide signal,
whereas FSK31
