My version of Glens 10m 100mw xmtr.
Closer view. I used larger toroids, glued them down with double sided tape. Notice 56 ohm dummy load on right straight from 4:1 output transformer.
Output right from collector of transistor. Set for .2 v per div.
Output from grounded base buffer. Pretty much unity gain.
The output across the 56ohm dummy load. This is with a 18mhz xtal.
