Forgive my ignorance but are the inductors in microhenries such as 2W05 is 2.5 microhenries?What is the component in parellel to the crystal?Any suggestion for the transistor besides hfe > 10 at 150 Mhz?This is KI6UMT needing a fox hunt transponder. Thanks.
Greetings!Excuse me for such a long delay....Inductors: all air wound, 5mm diameter. 2w, 4w, 5w - these are 2,4,5 turns.Regarding component parallel to crystal - resistor 4,7k.Re transistor - can't give recommendation (because I use old and rare russiand ones - I have a lot of them). Look for any Ic~100mA capable UHF transistor.Best 73! Klemens
