Impedance link on one of the IF transformers before the filter and this worked I tried tapping 21.4 MHz after the filter, but the bandwidth was too narrow forĪ good spread with the HF receiver. Second converter, to convert the 450 MHz output from the first converter down to The idea of all this was to use the scanner as a It wasĭead easy to arrange a coupling cap and a bit of coax to connect this to one of my HF receivers. It covers 450 MHzĪnd has a first IF of 21.4 MHz as I believe most scanners have. I have an old scanner which was found on the Maldon tip. Would be nice to own a Yaesu FRG 9600 or similar to use as an IF but this luxury Monolithics/Hills) which convert 2401 MHz down to 450 MHz. I have obtained a couple of downconverters (Conifer and Pacific The AMSAT-OSCAR 40 satellite on 2401 MHz.
