We'll, I successfully completed the 6400 Memory Channel Modification from
|
|
Bill Cheek's Scanner Modification Handbook. With the help of a veteran
|
|
electronic's wizard, I completed the mod in just 5 hours. We ran into a
|
|
few problems along the way, so I thought I'd make them known to anyone
|
|
interested in performing this mod:
|
|
|
|
1. We didn't use color-coded wire to wire the extended memory chip to the
|
|
circuit board of the 2006. No problem.
|
|
|
|
2. We ran into difficulty in that Realistic changed the location of the
|
|
main memory chip (IC-505) and placed it behind the keypad (front
|
|
panel). A minor slowdown to find the chip.
|
|
|
|
3. Behind the front panel is a metal shield which, I believe, is new.
|
|
We just de-soldered the panel and removed it to do the work.
|
|
|
|
4. Some of the solder pads were very close together for some of the
|
|
soldering.
|
|
|
|
5. You must use care in not heating up the solder pads too much because
|
|
they will pull up from the board. We had to solder right to the trace.
|
|
|
|
6. The IC-505 chip in the 2006 was machine mounted(?) onto the board so it
|
|
was unable to be desoldered and had to be clipped off, thus ruining the
|
|
original chip. Not a problem if the mod worked! USE CARE!
|
|
|
|
Other than these few notes, we had no problem with the modification.
|
|
I definitely would not advise the average scanner owner to attempt this mod.
|
|
It was very difficult for the two of us to do, and my friend has many, many
|
|
years of computer and electronics repair. NOT FOR THE AMATEUR. (Like me.)
|
|
|
|
All in all, it was a success (luckily) and I now have 6400 channels of memory!
