Title: ID Mod Transformers Post by: John K5PRO on January 21, 2006, 08:56:38 PM I have two Collins Mod Transformers, one from EPAY and another from a local SK's junkbox. Turns out these are the same beast, just different packaging and vintage. I need help identifying what they came out of. Must be something common, because the guy on EPAY was selling a collection of them one at a time, months ago. Then I found this one in town.... They are a little large to use in a DX100 or Apache.Thanks for any advice: AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
