A result of tying neutrals to each house ground is that there can be sizeable voltage differences between two house's grounds. Years ago I had an "informal" TV cable system with two amplifiers each a

Some of you may be interested in the modification I made for adding *6 meters*. to my SB-1000 (same as AL80A) Look up my call sign, *KU6X*, on *QRZ.com* , it's at the bottom. 73, John, KU6X _________

The main issue is the excitation current of the transformer. If the transformer was designed (with enough turns and core cross section) for 50 Hz and your running on 60 Hz then you have an automatic

Some wire wound resistors are MUCH better at handling the energy stored in the cap bank + the energy delivered by the line before the line breaker trips. I've found that the 25 watt Ohmite Brown Devi
