I have a modified SignaLink with a small toggle switch on the chassis that allows me to select EITHER pin 4 or 5 for RX audio.
So on the fly, I can switch between pin 4 direct or pin 5 (de-emphasized and filtered RX audio).

This is EXACTLY what I do with all my home-brew interfaces.? Here are a couple...
Barry, Stephen, all;
The original poster is using his DigiRig with a dual-band VHF / UHF FM transceiver. As pointed out by other posters on this topic, if you can achieve reliable connections with VARA FM WIDE, with the VHF / UHF FM radio and interface device both configured for 9600bps data, there¡¯s no need to switch the radio and interface to the 1200bps configuration for either VARA FM NARROW or 1200bps packet operation.
This is not to say that being able to conveniently switch the interface device between 1200bps and 9600bps is not worthwhile, particularly when working with an ¡°all band¡± (HF / 6M / 2M / 70cm) radio. It just isn¡¯t necessary when working exclusively with a dual-band (or single-band) VHF / UHF FM transceiver.
