Setting the communications delays
In order to accommodate rigs with different communications characteristics and computer processor speeds there are two delays that can be varied. These delays are set using sliders which are shown in the spectrum display area of the main screen when the checkbox 'Delays' (to the left of the On/Off button) is ticked.
When the delays have been set you can uncheck the Delays checkbox to clear the sliders from the spectrum area of the screen. These settings can be varied at any time, and are held separately for each rig type.
This is the number of milliseconds delay after sending a command to the rig. Most rigs can usually be set to 0, except the VR-5000 which usually needs 25-30 milliseconds delay to avoid occasional Low Voltage errors when tuning quickly using the mouse.
The number of milliseconds the program will wait before it issues a Read S-meter command. This delay is required to allow the AGC to settle on the frequency just tuned to, otherwise you will not get a true reading.
Switch to an active band - say 40M - and start a Spectrum Scan. Adjust the S-meter slider to a level that gives satisfactory readings. If this delay is set too short you will not be able to successfully stop on a busy channel when scanning. A 'starter' value of 30 milliseconds is suggested.
Note: The S-meter in the VR-5000 does not appear to want to talk to the PC unless VFO B has been activated by pressing the M/S button (next to the Power button). You will not be able to read signal strength without it being active.
An additional number of milliseconds the program will wait before attempting to read the S-meter for a Bank memory that has CTCSS Decode specified. The range is 150-300 milliseconds. A suggested starting point is 250 milliseconds. Vary the number until you find the rig is reliably stopping on the memory when a signal with a matching CTCSS tone is being received.
