Well I just finished with the THIRD cobra 29 radio (Chrome) with the Mosfet mod using the kit I put together. and we are swinging for the fences again with an output of nearly 50 watts ( I may back it off a little to keep the Mosfet from dying)
We used a different meter this time On a LP 100 with a dummy load and confirmed my original radio was doing 40w PEP.
Seems to me that the combination of switching diode and 270ohm resistor to replace R56 works great. And an all Ratshack build using the 510 gets us near 40 watts. ( had to test that in the radio then flipped in the 520)
I think people may have gotten the impression that all Mosfet builds require the en1230. Id say try a 270 ohm and switching transistor in parallel and see what you get. Be sure the band on the diode is facing the front of the radio.

Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned
