Hi,
I’m going to set up a Digirig Mobile - Logic Levels (default) device on a analog MFJ 6 meter transceiver. It has a 4 pin microphone din connector (similar to a cb mic pinout). It also doesn’t have aheadphone jack so I’ll be adding that. There is also an amp keying circuit on the rear. Are there any wiring diagrams for similar setups or harnesses I can modify?
Thanks for the pinout diagram and suggestions. Receive works great but when I plug in the 5 pin din and transmit it works correctly (both RTS and VOX work) but after transmitting the receive level is pegged in WSJT-X and there is a hash on the waterfall. Is this a ground loop issue?
SO one more concern- I think I’m drastically over driving the mic input at the transceiver with the line-in voltages. Transceiver has no line-in port. Is there a simple way to attenuate that line with Digirig or should I just build a small attenuator between Digirig and the transceiver?
Thanks for your comments- yes slider turned down. From what I’m reading dynamic mic inputs expect just a few mv’s and line-in can be almost a volt so lots of attenuation is called for here I believe.
