1. [AMPS] FT-240-61 core, where from ? (score: 1): Author: F.G.Robertson@open.ac.uk (Fraser Robertson); Date: Wed, 23 Dec 1998 12:07:20 -0000; I'm looking for a UK source of these, or a suitable equivalent. Ferromagnetics (GW3TMP) no longer import them. I want them to make 50/75 Ohm 2-30MHz QRO transformers. (The design is from the 1988 ARR; /archives//html/Amps/1998-12/msg00342.html (8,410 bytes)

Any rig or amp worth using will load directly into 75 Ohms with no problem. Not all the world has 50 Ohms as a standard and the mfg designs for the variations. I use 75 Ohm cabl; /archives//html/Amps/1998-12/msg00346.html (8,487 bytes)
