Cold Shack - Any Concerns?
Rusty Zimmerman
My shack is in a 10x16 Shed that is outside of my house.? It is
insulated but not heated when not in use.? Anything I should be
concerned about with my gear being out there?? Anything specific to the
IC-7000? I use it as my main rig out there along side a couple 2m and
70cm mobile radios.? I tend to turn on the heat when I'm out there for
an extended period of time but it rarely gets above 60 degrees.? With
the winter winds it can sometimes get pretty cold in the shack. -KB9PBX |

Re: Mobile speaker

Regardless what speaker you choose, try it in different locations in the vehicle before you mount it permanently.? You will be surprised how physical location affects the sound.? Even a small speaker sounds good when placed on top of the dash up close to the windshield. Be careful though - I once had a speaker mounted on the door post near my left ear - sounded good but didn't feel so good when I hit the curb one day accidentally. Jeff W4PJW |

Please ignore. I have trouble shooted and eventually resolved the issue. I have however noticed the Icom runs hot with a burning smell after a couple of hours of use. Do any of you use external fans. Also when buying new should anything go wrong do Icom have a warranty scheme. I'm guessing by law they have to. I know the shop I purchased from only offer 28 days.Haven't had an issue. Mine runs warm, but not excessively hot. The one in the shack has run 24x7 for most of the past few years. -- 73 de Tony VK3JED/VK3IRL |

I don't know where you are, but mine has a 1 year warranty from Icom, and an added 2 year warranty from the merchant. Should allow me to "burn it in" in that time! Many shops allow you a certain time to return the merchandise, then it is between you and the manufacturer.

Re: Finals idle current adjustment - does it sounds like my 2m finals are blown?
Just to clarify: ?The FET on the small board is the driver (Q504). ?The pre-drivers are Q101, Q102.?The first adjustment in section 4-4 sets the Driver idle bias. ?The remaining steps adjust the PA idle bias. I would check the bias voltage (ID3V) at R501 and at the gate of Q501 (VHF PA) to see if it varies when you adjust it. ?If it does not, then there may be a problem with the bias circuit. ?Otherwise, Q501 may be defective. I haven't seen your symptom. ?The two Q501's that I've replaced both had low output, but that's a small sample. Steve, W3AHL |

Finals idle current adjustment - does it sounds like my 2m finals are blown?
garymortonuk
I was operating the IC7000 on my desk when it emitted smoke. I quickly turned off and opened up to investigate. I confirmed that the pre-driver board was blackened, which according to web searches appears to be a common failure mode with this rig.
I ordered a new transistor from a UK supplier at a cost of UKP15. Removing the pre-driver PCB wasn't particularly difficult and after some effort and help from a friend was able to remove the old surface mount transistor from its tiny PCB and replace it with the new one (but I would recommend to anyone else to buy a new complete pre-driver board assembly!). Surprisingly there was no sign of thermal grease having been applied between the transistor and the heatsink/case, so I added this for the new transistor. It all went back together OK. I followed the instructions for setting (what I believe to be) the pre-driver idle current for each frequency band - there are four settings: HF/50-1; HF50-2; 144M; and 430M. The HF/50 and 430M settings adjusted OK, but worryingly the current on the 144M setting didn't change from the base value. My question is - does this point to the finals transistor having blown? The strange thing is that operating the rig in FM mode on 144MHz it does put out 40W of power, which would surprise me if the finals transistor was toast. In USB mode when viewing the power meter the needle doesn't move much except on loud sylables. It sort of makes me think that the bias is missing as if the transistor is operating in class C. Perhaps its just wishful thinking that the final transistor is OK. Has anyone seen similar behaviour? regards... --Gary (M1GRY) |

Re: FM flickering green recieve light
Hi. Thanks for the replies. For some reason I am responding to msgs but they are not showing up. Perhaps as I'm a new member the moderator is checking my msgs before they are publically posted. That is exactly what happened though it was acting as squelch on FM.

Re: FM flickering green recieve light
As I remember it, the IC-7000 has a default setting which makes the "RF GAIN / SQL" knob act as an RF Gain knob in CW/SSB mode, and as a _squelch_ knob in FM mode. A flickering green light -- especially combined with intermittent noise from the loudspeaker -- means that the signal on FM (if there _is_ a signal) is strong enough to open the squelch _sometimes_. Suggested cure: . . . Raise the setting of the RF Gain/SQL knob for FM, or: . . . Use a menu setting to change it to an RF Gain knob _in all modes_. . Charles VA7CPC PS -- forgive me if this is out to lunch; I'm working from memory, not the manual. |

Re: [IC-7000] Mobile speaker
I'm using a R/S 10-w amplified-speaker. Works rather well, but don't know if they're still available. It's mounted on the top-of-the-dash 'dish', which I cut holes into to allow the audio & DC connections to pass through. or?? ($39.99) On Tue, Dec 3, 2013 at 10:16 PM, <jlfisher@...> wrote:
