Re: LF: EA5DOM back to MF, but QRP at the moment

Hi Graham, MF

Good idea. Let's see where is the imit

I have just connected the U3 directly to antenna. Have not measured power yet but may be under 500mW

I'm not using the 3xBS170 but a mosfet driver instead, ICL7667 if I can recall correctly

Spots in WSPR dropped to just the EA monitors

Hi Luis

 

Nice going  for  5  watts,  but  -8 dB  with  75 % of the  signal  recovered ,  your  nearly  +30 over the  limit .. can you drop the  power down by  20 dB ?  say 50 mW ??
