Typical of this rig. Keying had a twang. I am recording from my IC-7300 via a microphone into a computer. QSO is with a friend who runs the Omni VI Plus.

He had a large garden for many years when younger. I'm glad he got to enjoy these few
tomato plants.

Here is a simple direct conversion receiver (TenTec 1056) using an outboard DDS VFO by N3ZI. I have programmed the VFO for an IF frequency of +750 Hz and an RIT of -1500 Hz. Using this too we can move from one sideband to the other by simply switching on the RIT and move away from QRM. The display is set to show the RIT frequency. Doing so allows the display to show the proper "center" frequency. Sounds complicated but it's very simple.
Another feature is now we have an accurate way to tune for the exact frequency. Simply tune and keep flipping the RIT switch until there is no pitch difference then read your frequency. Note the "Spot" button , lower RH corner. It does the same thing as the RIT toggle switch.
