The next Question would be where I can get the 1/2" x 1/2" or 1/2" x 2" Ferrite Cores and the HF Transformer

usually 43 for the input transformer and 61 for the output @ 27mhz
YMMV
The attached pdf has a parts list for a 27.120 ISM and lists Fairite #61 for the output.

It's interesting that the 27 MHz. test circuit really appears to be a broadband HF circuit...
