Speaking of the FT-817ND. I have a problem with the (expensive) E-DC-5B
cigar lighter socket 12v lead. It is supposed to be regulated, 12-16v
input, 12v output (2A).
I have heard of several having a problem with a voltage drop using the
cigar socket and I appear to have the same problem.
Using the voltage monitor on the rig itself, 12.4v is registered. Fine,
close enough to 12v, not a problem one might think. Wrong.
Using the various outputs, 0.5W, 1W, 2.5W and the full 5W which is what
one uses the car supply FOR, one finds that the voltage DROPS considerably
switching to high.
The voltage varies between around 11.8v and on the 5W setting, it drops to
10.7v. This of course is not enough to supply 5W so it immediately goes
into the three flashing bars mode which tells you that it is only putting
out 2.5W. :-(((((
I have yet to check my cigar socket voltage. I suspect that it will NOT be
the expected 13.8v which is standard voltage for a car battery. There is
obviously not enough voltage to enable the regulator to regulate.
I am wondering how I can "UP" the voltage to the cigar socket. :-) Highly
unlikely. I suspect that I will have to feed a fused lead directly from
the battery as I did with my FT-290R to prevent such problems.
In the old days, one could NOT use the cigar lighter socket to draw heavy
current. The lighter itself possibly using a 3A or 5A fuse. The threat of
a fire due to pulling too much current was real. This could easily cause a
fire in the wiring harness. NOT a good thing to have and very expensive to
repair. Now it seems that many use the socket to drive high power (50W)
dual-band rigs. Things have changed. I think mine has a 15A fuse so should
be fine for drawing current but is evidently having a voltage drop for
some reason. I wonder how others cured this problem if at all. Regards,
Jeff.
