Re: [IC-7000] Battery operation

Hi all,

I am 100% mobile and have struggled with 7K dropping its output power as the
battery drops in voltage, which in the end means I either have to start the car
or run on low power.

Well I have been experimenting for some months now on battery packs to give me a
reasonable amount of time to transmit and have mixed results!

The first plan was to make a battery pack and I was lucky to pick up 4 off 160ah
batteries from a job which the customer didn't require them any longer! I
fabricated a box and connected them all in parallel and terminated them with a
forklift plug. This made charging easy as I made a connection jump lead from the
vans existing battery.

The first test I tried was not as I had hoped, as after about 5 minutes the
power on the 7K did its normal and dropped. Checking the voltage it showed that
it had only dropped to about 12.3vdc but still had loads of amps left!

So like all mad engineers, after a lot of head scratching, I soon realised that
I would need to increase the voltage.

I my yard I have an old fork lift which has got a major drive issue with one of
the cards so I was going to scrap it, but the batteries all 36 of them are 2v
cells at 100ah!
I have now connected the 2 volt cell in serial with the 4 off 160ah and on the
10th April I managed 5 Ĺ hours before the radio went to low power.

So far I have had no problems with the charging or the van electrics but she
start first time now! I will put some photgraphs up later.

Cheers

I agree. I own also a TGElectronics one, the Marine Booster type, and it is worth every cent.
But on the other side, one has to pay good attention to the batteries, it is better not to run them until the booster switch automatically off ; car type batteries accept strong load surges and strong reloads, but do not love it seems to be fully discharged too much times .... In my opinion , a battery digital voltmeter directly on the battery terminals helps .

Hi -- this does not directly answer your question, but ...

I have been using the N8XJK battery booster (http://stores.tgelectronics.org/StoreFront.bok) and am very pleased with it. I am able to get a full 100 watts out of the 7000. I didn't measure actual voltage at the IC7000 end of the power lead, but unloaded, the booster was putting out 14.1 volts.

In my opinion, battery operation of this radio really needs the booster.

Re: [IC-7000] Icom 7000 and contest conditions

David Pykett
 

Hi John

It wasnt the bandscope causing the problems was it I have noticed the effect
on received signals when it is on and I quickly turn it off again. It in my
opinion the worst feature of an otherwise excellent transceiver.

G0IIQ







Last Thursday I turned the Icom 7000 on using 40 CW, put the bandscope in
slow sweep mode, and noticed some big signals 30 KCs up or so, so I tuned up
there to see what was going on. It was the NCCC sprint which I had forgotten
about. I had the 7000 set up for normal 40CW operations-preamp off, 500hz
filter, sharp filter, fast AGC. One thing I quickly noticed was that the
receiver seemed to be getting hammered in this sprint. The AGC was pumping
badly, and it just didn't seem to be up to the task. Signals were difficult
to copy, as they were being affected by other signals outside of the
passband. I hadn't noticed this problem with other small HF/VHF/UHF rigs
like the Yaesu FT857D and Yaesu FT100D, which I have run in contest
conditions also.

What was going on? Did I have the rig set up incorrectly, or is the receiver
in the Icom 7000 just not up to the task for this type of operating?

Thanks for all of the feedback.

I took my spare battery (65ah) into the house along with the ic7k and connected it to a buckmaster OCF windom (80 M version)and hooked up a watts up meter inline with the battery.

I was able to transmit at full power, no cutouts, loaded voltage never dropped below 12.2V. This same battery was having the previously described issues when used in the vehicle on the Tar Heel 200 and Turbo tuner.

This appears to point to common mode current on the coax.

Next step is to try and bond the vehicle and use some ferrite chokes at the antenna side of the installation.

I am guessing that the bonding will have the greatest impact as the hitch receiver is about the lowest metallic point on the vehicle. Bonding will probably start with the easy stuff like the exhaust system to the truck frame, the bed to the frame, the cab to the frame, the hood to the frame, etc. I will probably hold off on drilling holes in painted surfaces such as doors. I am not looking for perfect but for reasonably good.

Anybody care to comment on the tests, results, and going forward direction?

Any health risks from the common mode current?

Also, I am assuming that if I am doing an LXPedition (search for Atlanta LXPeditions yahoo group) and am using an external dipole hanging from whatever is handy that I will not have the problem either.

Thanks again and 73.

I don't know how many CW ops we have in this group, but I've noticed
something similar.

I don't see the AGC being affected that much by nearby CW signals, but
I have noticed a 'hiss' in the noise floor caused by strong nearby
signals. The hiss corresponds to the dits and dahs of nearby signals.

By listening to this hiss, I can sometimes copy strong signals that
are as far as 8 Khz above or below the received frequency. I've never
noticed any problems from a signal 30 Khz away.

This is most pronounced with the filter set to 1.2 Khz, but if the
signal is strong enough, the affect can be seen when I have the filter
set to 500 Hz.

Rigblaster PnP using data jack

Stephen Atkins <satkins@...>
 

Hello everyone. I ordered an PnP which uses a 6 pin din. I also have ordered the cable to convert that 6 pin to the 13 pin acc for the 7k but its back ordered for a few weeks. Looking at the pin outs for the 6 pin it seems like it should work with the data jack on the 7k. In fact it does key the transmitter and I can send and receive the audio from the computer to rig. So connecting it to the dummy load and setting the audio level to about 10% I tried sending. I had a second rig to watch the signal and man where there a lot of side bars all up and down from the center tx frequency. I turned the audio down to 5% but still lots of bars. Even at 1% it was not a clean signal (and only 1 watt out on the rig). I made sure compression was turned off but I'm not sure what other settings may need to be used.

I've heard a few people say to use the data jack for psk/rtty as it doesn't engage the mic but now I'm wondering how they where able to get a decent signal. Does anyone have any ideas or am I stuck waiting for the ACC cable?

Thanks

Re: no power

Peter
 

Phil,

When hit the power and it just does the clicking sound and nothing. No startup screen, no other sounds, this phenomenon may can caused by some of contact pins/terminal between the front panel and main body with a poor contact.

To verify if the problem is caused by these contact pins/terminals (with a poor contact), you can move out the DC power then detach the front panel from the main body and using a cotton swab with a little clean solution to clean both of the pins and terminals on the front panel and the main body.

Hope the a above information can bring you with some help.

kd5ntl,

I have the exact same problem. Did you ever find out what was wrong?

My 7000 started doing this after very mild use, maybe 50 hours. The unit experienced no trauma, water drops, extreme temps, etc. The odd thing is the problem simulates a totally dead radio, but then at times will surprisingly work just fine for no apparant reason.

Ex: Saturday 4/18/09 I got motivated to solve the problem, thinking the the culprit was just a bad ground or bad/insufficent wiring. I rewired the entire rig taking my time to ensure proper power delivery. I hooked it all up and as I expected the radio started up and worked fine. I received and transmitted for 3 minutes with a big ole smile on my mug and turned it off to pack the tools away and get cleaned up.

Not 10 minutes later I try it again and its back to not working. Hit the power and it just does the clicking sound and nothing. No startup screen, no other sounds. I then try everything I know to eliminate the possibility that power is not being delivered. I took radio out and "hard wired" it another vehicle straight to the battery. No extra wires or connections. Just radio to factory wire harness to battery. Still same problem. Have checked wire harness with multimeter and it seems good.

My guess is a bad power connection somewhere inside the radio. The movement of the radio during my re-wiring of the truck may have been enough temporarily allow for power delivery. It cant be fuses as it works fine at times. It cant be antenna or load related as it never starts up to even have a problem with receive or transmit. It has to be some random force causing a power disconnect. I dont think it is a temparature problem either as it just wont start up to get hot enough to be too hot, if you know what I mean.

Can anyone give me a clue? Is there a known circuit board problem where power connecter plug meets circuit board? I am off to AES tomarrow where I bought it as a first step. It is past the 1 yr warranty. I will post more as I learn more.

Thanks,
Phil

Re: [IC-7000] Re: Visalia DX Convention

Eddy,
 
I attended the Visalia convention last weekend and enjoyed myself very much.  Bob Heil gave a talk on "articulation", by which he was referring to the importance of a crisp audio signal in order to bust pile-ups even if you don't have the strongest signal.  He demonstrated some of his band tuned microphones.  His new product, however, is actually a pair of noise cancelling headphones due out in about a month or so.  No model number yet.  I tried them at the Heil booth and they were light, comfortable and just about neutralized the background noise in the exhibit hall.  The battery lasts about 70 hours, he said.
 
I also won a $1,300 M2 KT34 antenna in the raffle. (Hey, maybe THAT'S why I "enjoyed myself" so much)  Unfortunately I don't need another antenna so I will probably end up selling it, unopened in the box.  Final decision on that pending.
