Hi Glenn, Yes I did! I paid something over $350USD for a set of 8505A originals. They come in three, 3 inch, 3-ring binders, and about 50% of the pages are fold out schematics. Each binder is packed

Didier, this is fine providing that 1) the 5K resistor is at the T-piece end, and 2) from the non T-piece end of the 5K resistor, you put a ~50 ohm resistor from t

Re: Measuring frequency on a 50W transmitter
The counter's input stage, whose geometry has about 1/1000 the size and thermal mass of the fuse, will do a great job protecting the fuse. :) A pair of back-to-back Schottky diodes, perhaps the kind

Re: Measuring frequency on a 50W transmitter
Most VHF/UHF frequency counters use a terminated 50 ohm input, usually rated at about 500 mW, and in this case, the fuse will provide protection, if you do something that you shouldn't have done. If
