G'day all,
I received my working IC-7000 back this morning, I have popped the bottom lid to have a peak on what was replaced, however as it seems there is a fair bit of de-soldering to do to get what I'm going to call the PA board out, (while we have some topics in the group on acronyms - I CBF, and just want to get back on air!) so I'm going to accept that the dealer has advised that it was a fault with the 'pre-driver', and is common with the 7000s. So, the LDG IT-100 gets let off the hook at this stage.
So firstly, thanks all for the replies,

re: power connectors, I'm just using the standard 4 pole block on the back of the Icom, and about 20mm Eye's onto the screw terminals of my PSU, will probably look at a 'double' Anderson type connector when i set up in the mobile, as i am using those with all my solar gear and haven't had any problems with them at all.

re: tuning up power, if I hit ether the tune button on the radio, or the tune button on the LDG, the radio only TX 10W CW (even with normal tx power set at 100%) for the duration of the tune cycle (tested into a dummy load direct out of the back of the radio) Note that the tuner cuts the tune cycle short when it receives no TX power on its input.

re: power/data connector between radio and the LDG IT-100 - mine is a molex on the radio end (same as Hard drive power connector), and what Wikipedia calls a 4 pin circular connector (what I call a S-Video connector) so in this case I am lucky that things cant pull out and touch adjacent connections on either end all that easily.

Looking forward to get back on the air when I get home from work tonight, catch you there.

Cheers,

Bill:



The strip is a RIGrunner, which is perhaps the most common PowerPole
outlet strip. If they had recessed the connectors on that, you
wouldn't be able to do this, but they didn't, so, OK, they setup
this potential fail situation. But of course you can do this with
single PowerPole cables also.



For example, below is a single set of 70A PowerPoles connected
offset (if image doesn't display, follow the link). Yes, they can't
be connected backwards, but depending on what you're connected to,
you could short out the supply line. Why? If you don't have a fuse
on the radio negative lead and you plug in this way into a
high-current source with the radio and supply grounded some other
way (coax, ground terminal), there won't be a fuse to protect your
wiring and you could have a nice little fire.



(Now backing out of this thread.)
