Another thing about split operation is that the K3 defaults to using
VFO B for transmit and A for receive. In the K2 A/B (I think) reverses
these. This is a bit of a problem if you are using N1MM and running in
split mode and tuning VFO A around. If you tune more than 300 Hz N1MM

Would this be suitable for the IF output of the K3? What

Jim,
Using an old-type VOM is not a good idea because the instrument's input is
fairly low-impedance and can thereby compromise accuracy, especially when
measuring at a high-impedance node. DMMs are ubiquitous and can be purchased
at any Lowe's or Home Depot for around $20 or less. Throwing a

Hello Nick,

When that happens, the voice coil may come into contact with the magnet
