Default Re: Marconi NS702 / 2207E, SN 623 (Atalanta type) receiver

I changed the function switch to a 6way switch, added a small PCB with two reed relays and two behive trimmers, set the BFO to 86.5khz and the relays bring the BFO to 86.0 for CW and 83.5 giving LSB, USB and CW mode on the function switch.

Has anyone tried the IF mods in Practical Wireless from March 1983 adding in an additional EF85 in the 700kHZ IF and an additional W77 in the 85kHz IF?
