IIRC that configuration of that hacked RSS was sometimes referred to as
"Range 1.5". It had its v-bit splits modified to support the ham band,
but the retuned radio would have to be compatible with the implemented
ranges in order to get working results. I.e. you'd have to reconfigure
the VCO capacitors to get lock, as well as retuning (probably both sets
of) filters.
This is why syntorxgen lets you set your own v-bit splits. (It'll also
let you invert which setup is used for transmit, and which receive,
because it looked to me like that might enable converting a UHF T-band
VCO for use around 420-440. The Range 1 radio won't go high enough for
that. Some ham UHF link channels around here are in the low 430s.)
