- Look here
Web Info
- MAX COmputer Interface
- TELCOM's IC-R2 page
Other Info
- The Pouch, model #S510-T8, makes a fine case for the R2. Check with
the larger ham dealers to pick one up.
Programming Info
-
Since I get asked how to program the scan edges on a regular basis, I thought
I'd save some time for all of us and include a little tutorial on how to do so
-
What Icom calls a program scan, I call a limit search
What Icom calls scan edges, I call search frequency limits
-
So if you try to relate what is presented here with what is documented in your
R2 manual, simply interchange 'program scan' and 'limit search', and 'scan
edges' and 'search frequency limits'
-
Performing a limit search consists of 3 steps:
1. Programming the search frequency limits
2. Selecting the search mode (limit search in this case)
3. Starting the search
-
Step 1
First, I must assume that you know how to program frequencies, steps and modes
in the VFO. This is where you'll need to program the limits in step #1 above.
From there, you do a memory write operation to one of the edges.
If you go into memory mode and cycle through the banks, you'll eventually come
to the scan edges bank. You'll know you're there because the channel number in
the lower right corner displays things like 0A, 0b, 1A, 1b, etc. Each number
represents a limit pair while the 'A' and 'b' represent the lower and upper
frequency limits.
So you tune the VFO to the lower frequency limit and then program it into 0A,
for example. Then enter the upper freq limit in the VFO and program it into 0b.
-
Step 2
For step #2, go into VFO mode and press FUNC + BAND. This is where you specify
the type of search to be performed. The selections are ALL, BAND and PROGRAM.
You want the PROGRAM option which is labeled PROG and allows selection of one
of the 25 limit pairs (0-24).
Use the rotary control to select PROG 0 (if you programmed 0A and 0b above).
Press BAND to keep this selection and return to VFO mode.
-
Step 3
Go into VFO mode and if necessary, set the receive mode and step size for the
search you're about to perform. To start the search, press FUNC + UpArrow to
start the search upward, or FUNC + DownArrow to start downward.
-
That's it! You should now be searching between the two frequencies programmed
into search limit 0.
-
Program the other edges accordingly via step #1. Select the desired limit to
search via step #2. Start the search via step #3.
