hi
We must be ready to the new solar cycle and repair or setup our old 10 meter hr radio (one of the best ever made).
here is a real good power modification for the hr-2510, hr-2600 and Lincoln.
Or use this as a upgrade if your MRF477 or MRF497 fail. I have done many of this mod/upgrades with exellent results.
Materials:
1 small washer
1 47uF to 100uF 25V capacitor
1 68 ohms resitor 1/2w
6 silver mica caps (values shows in pictures)(they are really needed)
1 SD1446 Pill (more cheap than mrf455)
1 small piece of wire
2 small screws (used to attach the pill to the radio cooler)
heat sink compound (silicon not metal)
Screwdriver, a drill and cutters
After installing all the stuff and power on the radio adjust am power to no more than 15 W dead carrier.
