![]() ![]() Retune the transmit and receive of radio for best performance. In the radio, replace C42 with a 3300μf, 16volt electrolytic capacitor.ġ4. In the radio, replace R48 with a 470K ohm, ¼ watt resistor.ġ3. ThisĮliminates a ground loop that can cause the radio to squeal on transmit.ġ2. Add a short jumper wire from the ground area at R142 over to the audio transformer’s ground pad. This re-connects the RX circuit in the radio.ġ1. To lengthen the leads of this part to make it fit. Rear hole of L12 on the solder side of the board. ![]() Using the 15pF capacitor that was removed from C8, solder one end to JP24 and the other end to the Ground tab on the back of the radio’s antenna connector.ġ0. Solder the RF OUT coax center conductor to the rear hole of L12. Solder the Orange wire to the front side of L15.ĩ. Solder the Red and Black wires to the back of the DC power jack (observe polarity!).Ĩ. ![]() Solder the coax center conductor to the front hole of R123 and the coaxħ. Route the RF IN coax through the hole where the final transistor was so that it can easily be soldered to From the radio, remove C8 (keep part for later use), C53, C57, R56, L12, and the final transistor.Ħ. Drill and mount the RFX75 on the back of the radio using the supplied hardware.ĥ. Take care to cut it close enough to the PCB so that itĤ. Cut the RX OUT coax cable off the RFX75 board. Cut the Yellow and Blue wires off the RFX75 board.ģ. Locate the capacitor at C10 on the RFX75 and carefully cut it off the board.Ģ. What did we talk about on CL? Yeah it is a small world after all, lol. No cause the directions I went by told me to cut out C10 and the RX Out Cable. ![]()
