Mod Transformer
Anyone have a modulation transformer for a pair of 811's/813'?

Use one out of an ART-13. They are plentiful and cheap.

I have seen a number of them on eBay. I am sure there were more
transformers than radios. I acquired 2 in a short while with no serious problem. It is a good transformer because it is sealed in oil - which means it is immune to the moisture that many transformers seem to absorb when stored in basements or barns. Colin K7FM |

I am sold but all I can find on the classifieds are WTB's so it may be poplular but it does not seem to be very common. js -- PHOTO OF THE WEEK: http://schmidling.com/pow.htm Astronomy, Beer, Cheese, Fiber,Gems, Sausage,Silver http://schmidling.com |

Good thing I acquired mine when they were available. I know I saw one for
sale not long ago for $20, which is a good buy. they have a separate winding for the screen of the 813. This makes it easier to get 100% modulation, without having to match the screen dropping and shunt resistor resistor. 73, Colin K7FM |
