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.)

Hi I am new to the group and to my new ic-7000 what I need to know I want to programme 433.1250 which is the Scunthorpe repeater in Lincolnshire which I have don the only problem I have is the transmit frequency which on my radio is 438.125.00 this should be 434.7250 can any one help me to sort this out
many thanks m3hvu

Your point about "better idiot"
is correct, but I think you missed my point about the offset power pole connectors, and this idiot has done it.

If you offset a PowerPole connection so that the Black (-) side of the radio/load is plugged into the Red (+) from the supply, AND if the radio and the supply have a common ground of some sort, which is most often the case (via coax if nothing else), then you'll have a direct short on your power supply. The connectors will easily plug together this way and I did do this one day.

I have a PowerPole outlet strip on the far right side of my bench. I had a radio I was working on that had the coax from one of my switches plugged connected to it. That connected the chassis via the coax to my station ground. When I reached over to plug the PowerPole connector from the radio into the outlet strip, I didn't quite reach far enough and ended up with the Black from my radio in the Red on the strip. With that strip, the fuses plug into the front, so I immediately noticed the small flash from the fuse as it popped and knew right away what I did. No damage done because of the fuse and the current handling of my DC source--which is why I like fuses.
?
Consider this, however, if you're relying on the fuse on the radio power cord and don't have proper fusing on the supply source (or battery line) and there's no fuse on the negative side of the radio line, you will burn something up.

Re: [IC-7000] HRD, Signalink and IC7000
Well, I got it figured out finally. I need to make an excuse – as I age my troubleshooting skills are not what they used to be. Feeling pretty stupid right now, but found the cable I needed and finally got the Prolific drivers to install. Guess I was just blind and dumb for a while ;-) ? Now my only problem is with the DM780 software. I got my logbook database loaded, but for some reason the program won’t let me save changes to macros. That’s my only remaining issue, and I will have to take that to another forum I guess. ? Thanks for the response. ? K7PAX ?

Re: [IC-7000] unit cuts off then on
The 7K's reputation for being fussy about voltage is due to the poorly designed fuse holders excessive voltage drop, which should be replaced. ?My 7K's will transmit reliably at 11 volts and less, as measured at the TUNER port pins 3-4. ?This shows the voltage inside the radio after all voltage drops in the supply cable.
The TX output power does start to drop below 12 VDC, but no worse than the IC-706 or FT-857, when measured in the same way. ?Here are my test results (TX PO was 80%, since that is the maximum I would run on battery-only power -- typically less). ?Details of the test are in this group's Files section in the 7K TX RF Levels.doc file.

This appears to be true, as I can see signals on the waterfall in DM780, and it appears I can transmit, although I haven’t had time to ensure that my signal gets out. ? However, HRD, because it cannot connect to the PC, doesn’t run and interface with the HRD logbook. It wants a direct connection to the radio. OK, what do I need to buy? Is the serial programming cable from ICOM the correct thing? Can I just use a GPS programming cable from Radio Shack? Is it the same thing? ? Here’s the kicker. HRD, the exact same version, runs on my XP machine and controls the radio with nothing but the Signalink setup. I did, at one time, have a cheap USB radio connection cable that I got from KAWAMall on eBay, assigned to COM3 on that PC, which is what HRD appears to be using. However, it is doing it WITHOUT anything other than the Signalink connection. ?If what I read from Signalink about HRD is true, this shouldn’t work. I am stumped as to how it is working on the XP machine but not with Windows 7 in the same physical configuration. The only difference is I can’t map a COM port.? I don’t know how COM3 got mapped on the XP machine and stay mapped – unless you can install drivers and assign them to a COM port even when nothing is plugged in there. (The Prolific 2303 drivers are installed on the XP machine and run COM3.) I tried installing the same drivers on Win7, but was unsuccessful in getting any results. ? Anyone running this combo? How are you hooked up? If you are using a radio connection cable in addition to your Signalink connections, which cable/device are you using? ? Any help would be greatly appreciated. Thanks! ? 73,?

Re: [IC-7000] unit cuts off then on
Someone mentioned the early 7000s shipped with the spring-loaded ?1/4 turn bayonet fuse holders -- those are notorious for bad connections once they get old. Even the clip-type holders for the glass fuses get sprung and have voltage drop at higher current.?

Yes that is definitely a power supply problem. It is probably not the power supply itself, but would be the power cable connections, plug, or fuses that are not making good contact anymore. The IC-7000 is VERY fussy about voltage - I did a test a while back, and I think it was around 12.2 volts that the rig switched off. Voltage needs to be around 14.0 volts. Watch the voltage when you transmit, if you have a bad power supply, or cables and connections/fuses then you will get a voltage drop on transmit. If the voltage drops below 12.2 volts when you transmit, then the rig will switch off…..and will switch? on again when the voltage goes back up again being in receive mode.

is there anything in the settings that i could have inadvertently changed that might be causing this radio to cut off in a transmission and then come back on or is it time to send it back to ICOM for repair ? ? (power supply seems normal)

Re: [IC-7000] How much of the band will the radio transmit on?
if you do the mod that
allows you to go out of band and transmit, just what is the range
that that you can transmit on?
?1.8-30 MHz?
1.8 - 54 Mhz?
1.8 - 148 Mhz?????
It will do 0.1-200 and 400-470 MHz. But: the afrther away from the
HAM bands you go, the more the filters will limit the signal. So
using it on 70MHz will almost certainly be impossible, as an
example.
