KHz crystal in the radio for the RTC circuit. If there is no "padder" capacitor to adjust, the only solution is to replace the xtal.

From 1979, the time of my licensing, to May of this year, I never had a rig with a clock. Most had tubes. Does the rig work? Do you make contacts? Get good reports? Very sorry, but I fail to see the problem. (Laughing a little bit... ;_) )Alex Netherton

Hello all,It could simply be a lack of RMS stations within your area. Also, propagation can sometimes be weird.

How close are the nearest RMS gateways from you? -- 73 de Tony VK3JED/VK3IRL |

Re: display problem
I would track down shelding. I have seen some talk of checking the spring fenders on shield covers. I had a WWll signal generator with a pincil tube. It was a constant effort to track down leakage that excaped out the dial window. :-) 73 de KF7SLM, Jim Jim Ray, Sr. |

Re: [IC-7000] display problem
Tom, Try checking the power leads with a scope and verify that there is no crud on the supply.? Also check voltage levels.? You could also remove every excess lead from the radio when you test.? Finally try a line isolator connected to the radio, though that should only apply on transmit.? Does this happen when connected to a dummy load and a short double shielded cable and everything else except the power disconnected?? You may end up putting chokes on the power leads but do the other checks first. 73, Gordon Beattie, W2TTT@... 201.314.6964 Sent from my MOTOROLA ATRIX? HD on AT&T kb1rrx@... wrote: ?

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, VK3CLI Jordan To: ic7000@... From: cscott@... Date: Mon, 28 Oct 2013 10:31:38 -0400 Subject: Re: [IC-7000] RE: RE: PA fault, LDG IT-100 antenna tuner Cause? 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.) Chuck - N8DNX On 10/27/2013 4:17 PM, Bill Boyer
