I have been quite specific in the document referenced by the link, and
in several others on my website.
Perhaps you might study them.

To focus any discussion, could you be specific? It's rather hard to react to
such a broad statement.

Are you suggesting that Fair-Rite's published data for this part is
wrong? In extensive measurements of certain of their parts, I've not yet
seen that.
I stand by my comments.
I had good results with a matching transformer for 50-800 ohms for a
terminated KAZ receiving loop, that was wound on a binocular core of 73
material. Very modest turn count. I wound it as a conventional transformer
with wire-wrap wire to accommodate the small core. The loop worked VERY well

A very Happy Thanksgiving to all !
It was especially nice in the QRP ARCI 160m Sprint
last night and then with the family at dinner today !
Just a few of the many things to be thankful for.

Last night the 160m noise level was S5+ and hardly aQRPer could be picked out

Anyone with proper test equipment can measure and verify what I say below is
absolutely true.
I'd hate to see anyone accept this information as factual or accurate:
The single turn resonance of this core is around 10 MHz, with a Z at
resonance of about 120 ohms. Like any other ferrite core, wi
I've had good success winding matching transformers for terminated RX loops,
on these cores with wire-wrap wire.

Probably not much, you're only a very small percentage outside the calibrated
range for that slug. That assumes that the slug is ok (not dropped, etc).
You can check them several ways. I use a calibrated attenuator after the meter
with an hp 436a power meter after that (with the appropriate hea
Hi All, With the wealth of knowledge on here I thought I would ask this
one.
Can anyone put a figure on the displayed power using typical Bird 43
elements for 2-30mhz when used at 1.83.
My logical guess would be about -5% but have no idea really. 73 Clive

Hello Clive -
The Bird 43 specifications indicate +/- 5% of FULL SCALE reading, regardless of
slug type.
