Model 70 air cap ground strap.
#5

Yes I know, I should have a spool of 36awg delivered tomorrow. The best the my current 30awg windings will do is up to around 160khz if - which is what more or less what I calculated. I used the 30awg on the first rf coil also, so gonna rewind both and looking for the right inductance on the oscillator. I finally tried a real alignment with a 324 I just purchased. Radio plays, and I can dial it in by ear better to get my main listening station based on what it is at the moment. Still in process of building my lab back up. 

I am not sure I follow you on the strap, will take another pic of it to better show where/what it is. Thanks.
