Hi LF-ers...

Just a question for any user of the G3LNP loop (Radcom 99). I replaced
2N3819 (not available in Slovakia) fets with BF245. The current of the
complete preamplifier is only 10mA with 6V on drains of fets and 13V on NPN
TR3/TR4. I'm not sure if it's enough.

Hello Richard,

I responded direct to you, but the e-mail was refused :

I don't know the details about the G3LNP loop but I do have the datasheets of both 2N3819 and BF245 (as PDF's), that might help you to get it working with the BF245's.
If you want me to send the datasheets to you please let me know your e-mail address.
