Would 7mhz be too low as an IF for a transverter for 2m? What about 6m?
Im thinking 130mhz (LO - IF) might be too close to desired RF of 144. 14MHZ separation at 144mhz only 10% difference.
Obviously 6m would be relatively further away.
What are the rules of thumb for choosing an IF?
filtering is a factor of course but at some point filter performance needs to be too good to make it more practical to choose a different IF.
Looking for a use for a spare bitx40 I have and thinking about modding one of those Ukrainian transverters to use IF 7 instead of 28mhz.
