Chameleon V2L Mounted on a Bicycle Stored on a Balcony - IC-7000 (100W)

The bicycle was located on the balcony at the second floor.

Radio: IC-7000
Tuner: LDG IT-100 Autotuner
HF Power = 100W

This video shows a simple bicycle antenna setup. The V2L is grounded to
the bicycle frame and to the aluminum patio door to reduce the RX noise
in the transceiver.

Frequency operated:
40M

many choices (including the one below).

You may also want to check out RT Systems. RT Systems

I'm a (very!) happy customer. One plus is that you can "copy/paste" programming info from different model/brand to another. Oh, and excellent phone support. No, I do not work for them.

Good luck.

It's S/N is 0512733. All firmware versions are identical to my 2006 vintage unit S/N 0505370. There are a few very minor changes in components inside and the circuit board P/N's have changed in some cases, but otherwise it is unchanged over four years. My original unit was returned for warranty service in 2007 and had some updates applied for the driver and grounding fingers.

That spread of serial numbers would indicate about 7360 units were sold in NA in 4 years.

If anyone has a S/N significantly higher than 0512733 I would appreciate hearing about it.

Re: Received signal question

Steve W3AHL
 

It sounds like your radio has a problem. The 7K's I've tested all meet or exceed Icom's spec, which is comparable to similar radios. On HF the S-meter is calibrated for S9= 50 microvolts (-73 dBm) with the pre-amp OFF, which is the IARU recommmendation. On VHF the S-meter S9= 6 microvolts (-91 dBm) with the pre-amp ON, which is close the the IARU spec of -93 dBm.

S-meter readings vary a lot among manufacturers and models. For example see:

http://groups.yahoo.com/group/ic7000/message/27002

The 7K measurements given there were for a different radio that had been adjusted some and are for FM mode (the values above are a factory calibrated 7K in SSB mode).

As to why the radio seems deaf, I would suggest you find a local ham or service shop that has a calibrated signal generator or service monitor and verify the sensitivity first. Or do a side-by-side comparison with another radio on the same antenna.

If it is deaf on "all bands" (meaning HF, VHF & UHF), then possibly lightning zapped your site and damaged the front end circuits. Since HF and VHF/UHF are totally separate circuits, it is unlikely for a common component failure to affect both. Proper grounding and lightning suppression usually prevent such damage, in my experience.

If only HF is bad, then it could still be lightning damage, or just a random failure in the RX front end circuit. Another problem I saw once is one ham had solder balls on the tip of the PL-259 connectors, which spread the female contacts inside the radio's connector. When he changed to a jumper without the solder ball, the connection was poor, resulting in intermittent contact.

The radio probably needs to visit an Icom Service Center. There aren't any magic adjustments to you can make.

[IC-7000] Re: Clock setting.

Steve W3AHL
 

The radio is spec'd for 60C ambient, but the operating temperature inside the logic module case will be significantly higher than ambient. I haven't measured the operating temperature inside the logic shield around the battery. The next time I have a unit apart I'll stick a thermocouple there.

To replace the battery, which is on the bottom side of the Logic board, inside the shiny metal shielded enclsure that plugs into the top of the Main board:

1. Remove two screws holding the Logic board assembly to the main board and unplug it from the two stacking connectors by lifting straight up.
2. Remove the top shield from the enclosure.
3. Remove the Logic board from the bottom enclosure.
4. The battery is mounted with two surface mount tabs. Apply just enough heat to gently lift them off the PCB traces. I believe there is double-sided tape holding the battery to the board, also.
5. Flow just a little solder on the PCB traces to level the surface and reflux.
6. Solder the new battery in and reinstall everything.
7. Inspect the board stacking connector for lint or dust, which will prevent good contact.
8. Make sure the thermal pads and magnetic shields between IC's / shield and shield / case are positioned correctly.

You should work at an ESD protected station to avoid zapping the IC's. Also, make sure you don't lay the battery on anything conductive which will short out the surface mount tabs and drain the battery almost instantly.

You may want to get a copy of the 7K's service manual.

Just get yourself one of tens of thousands of Digital-to-Analog

Re: Does anyone know how to formulate the CAT commands

Charles & Sandra Cohen
 

This is an off-the-wall question, but:

. . When you send the "send the CW keyed memory" CAT command,
. . . . Is the rig in "CW" mode ?

It's possible that you have to set the mode, before using that CAT command.

Ham Radio Deluxe has a bunch of pre-defined function keys, and each one has CAT commands "underneath" it. Looking at the definitions of those keys might give you some help in figuring out how to format your own.

I'm sure that the general rule of digital stuff applies:

. . . Getting the first command to work is the hardest part of the job.

And you've done that already.

Occasionally questions regarding firmware upgrades comes up on this forum. I just got a new 7K in for testing and configuration for the local ARES group's digital go-kit.

It's S/N is 0512733. All firmware versions are identical to my 2006 vintage unit S/N 0505370. There are a few very minor changes in components inside and the circuit board P/N's have changed in some cases, but otherwise it is unchanged over four years. My original unit was returned for warranty service in 2007 and had some updates applied for the driver and grounding fingers.

That spread of serial numbers would indicate about 7360 units were sold in NA in 4 years.

If anyone has a S/N significantly higher than 0512733 I would appreciate hearing about it.

Re: Clock setting.

Has anybody of you changed the clock backup battery yet?

My IC-7000 is a little over 5 years now and the clock is often starting at 0.00 when I switch the power on. To me it seems that sooner or later all IC-7000 units will suffer from a bad clock battery. The battery is as far as I know chargeable and should in theory not need to be replaced.

Regards

The battery is soldered to the Logic board that located in the metal box that's plugs into the main board. If your not an electronic technicial and you don't have the proper tools, I wouldn't recommend doing it yourself. The metal box is soldered to the CPU board and isn't easy to dissassemble.

Re: Firmware Version Unchanged Since 2006

One forum member just reported he had S/N 05140149 purchased in 09/10, so that would indicate that about 9,000 7K's were sold in NA in 4 years.
