Re: [IC-7000] Smoke
Last night, December 11th. I also heard a pop and smelled an electrical odor.
No TX. I called an Icom service center this morning. They told me the driver transistor probably went out. I purchased this 7000 new from AES on April 5, 2012. It goes back for repair today. I've been considering purchasing a second new IC-7000 for my motorhome but now I may go to Yeasu. -Tom, W3TLN On Tue, Dec 11, 2012 at 7:57 AM, Teddy Edwards <teddy.edwards52@...>wrote: Hey All I am VP2ETE and have been running an Icom 7000 for just over 6about 607 UTC while in the heart of some DX ing I heard a pop and thenobserved smoke coming from the radio.

Low Speaker Audio
The IC-7000 is still new to me, having just installed it in my car last night. So, I have not had a chance to memorize all its capabilities and buttons (yet).
Last night, when I installed my 7000, I put the Rig in the trunk and the Head on a gooseneck alongside the console. Because the rig is actually in the trunk, I also purchased a MFJ-281 and plugged that speaker into the head of the radio. My problem is the audio is extremely low. Running the volume wide open, road noise sometimes is louder than the rig on 2m or 70cm. The MFJ-281 is an 8 Ohm speaker. According to the IC-7000 manual the audio out jack on the units head is 4-8 ohms. So, I thought that would match and work well. Turning the NB off does increase the audio, but not that much. What have others done in my configuration? Do I need to amp the audio? Hoping to hear from someone Bill |

I reckon my next investment ought to be a dummy load as i havent aquired one of thosee yet. I suppose it would be OK to find a free freqency no one's using and experiment there as that is the only choice I have at the moment.The reason I stressed a dummy load is that your ALC and power out will depend on the load you put on it. If you use the tuner to get 1:1, you should be pretty good. Yes, you should have a good dummy load. Check the swapfests. Someone usually has a Bird Termaline or something similar for not too much $$.

So basically what your saying is that I'm supposed to be running theThat may be considered the "old" way of doing it, but yes. There's no reason to turn the power down on the radio IF you are sure you have a good clean audio feed to it. Just turn the audio down. If you happen to have a little hum, or noise on the audio line, then you would do better to lower the power setting to something near but above the power you are going to run, and then run the audio lower than ALC to the level you want - but you really should clean it up. The idea being to have a better signal to noise ratio on the audio/RF signal. It is NOT a bad idea to do it by lower power output, just not the conventional way. No ALC should show when you are at your final settings, but the power should be at 30-40%, certainly under 50% of what the transmitter is rated at. Many run 15-25 watts on PSK. When you run the audio up to ALC point, many transmitters will start looking bad on IMD on those modes. As an aside, you should also run a tone higher than about 1500 (I use 1600) Hertz so that the tone's second harmonic is OUTSIDE the bandpass (2x1600=3200) of your transmit filter. People used to try to use lower tones on systems that weren't as clean as they should be and you could spot them a mile away. They would have more than one signal on the PSK band at a time. You could see them come and go simultaneously. Of course, the second signal was un-needed, and could/would take up space that someone else could be using. Really low tones could even have triple or quadruple signals. I've only seen one of those over the years. I think he was using something like 500-700Hz tone. In short, if you want to run the power control low, just make sure the ALC is not showing anything. Experiment into a dummy load and play with levels until you understand what you can and can't do. And, try to always stay above 1500Hz on your tone. This all assumes AFSK operation, and goes for all of the sound cards modes. Ever see a double wide MFSK signal? Lots of them were around in the earlier days. :o) Gary -- Web: NodeOp Page: Node 3055: |

The simplest way to think of ALC is as a limiter. The harder you >drive the transmitter, the higher the ALC should read. If you >increase the audio input from zero slowly, the power should go up >with no ALC at all until it reaches a certain point. At that point, >the ALC should go up and the power should stay the same. PSK should >run very low power, half or less of your full power setting, with no >ALC showing. Turn the power all the way up (100W), slowlySo basically what your saying is that I'm supposed to be running the radio at 100% power (100W) and to control the power level (on the meter) I increase the audio level on the sound card? |

Re: [IC-7000] Re: LDG IT-100 Tuner for the IC-7000
I'd also second Andy's recommendation on the LDG 200 Pro II. Both of the
pro versions have the SWR & PWR Meters and support the connection of two antennas. I picked up the 200 instead of the 100 because I liked the idea of it being able to handle more power than my transceiver. Take care! --KD0TVP Bob From: ic7000@...

It came down to the 100 200 and 1000 I would have liked the 1000 but price dictated. So it was left between the 100 and 200 model I went to a radio place and tried out both and other than power handling I could find no difference and if Id not have got a really great deal on the 200watt version I would have gone with the 100watt version. Anyway the price was right the unit was right and the LDG shows perfect when your in tune and has loads and loads of memory's for saved freqs and ATU settings.. Plus it works from HRD I also thought that should I be using the 7K on full power it is the limit of thw 100 LDG so hence another reason for going to the 200. That said im only using the radio at 30% to keep the black smoke away but from all comments it dont matter whether your transmitting or even receiving the evil smoke can still sneak out of the radio..
