Peter, yes I did! The 5109 give more power out on the upper bands but not more on 80, 40, 30 or 20. Off the top of my pointed head,? I would say about double the output power vs the stock 3904 devices. One thing I am going to do with my V6 is put a direct dc connection to the final mosfets and run those at 24 volts.?
One thing I noticed from Mouser is in March I bought 5 of the 2N5109 transistors for around $3. Now they are not in stock. So not sure where to buy them from.
