I.F. Amplifier - The I.F. transformer primary has 18 turns, the secondary
winding has 4 turns. The capacitors across the IFT primaries are 82pF. The input/output
transformer has 12 turns, tapped at 3 turns from ground. This transformer is wound
on a ferrite core. The mosfets are 3SK45's. The diodes in the product detector are 1N34's.
I use a six pole SSB filter from a scrap CB. The centre frequency is 7.8MHz. The -6db
bandwidth is about 2.5KHz. (added 02/05) |
ICOM CI-V interface with RS232 RTS to PTT - This page describes my home-built
ICOM CI-V interface. In order to connect most all ICOM radios to a computer, an additional
interface is required. The interface bridges the gap between the RS-232 electrical levels
used by the computer serial port, and the open collector shared bus used by the ICOM
radios. The interface, therefore, is not much more than a level converter....(diagram

IF Amplifier Circuit - Three of these amplifiers are used in series to build the
455 kHz IF amplifier. AGC voltage comes from the AGC Circuit. The diagram above shows the
circuit for the second IF amplifier. (added 02/05) |
