Re: Mobile power

dave_schacher
 

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.

Re: [IC-7000] Mobile power

k5end@att.net
 

KG6YGC is correct.

Let's look at the facts, logically.

Using a dummy load eliminates any common mode or other RFI issues that
may be caused by a problem with an antenna.

Therefore, if the problem remains with a dummy load then it proves there
is at least one problem other than an antenna problem.

If the problem does not remain during dummy load tests it suggests, but
does not prove, an antenna problem.

If the problem remains when using the dummy load it means that there MAY
exist at least two problems, and one of them could be the antenna.

Any personal website created by an individual without peer verification
or industry endorsement does not fulfill requirements for installation
practices. The caveat is, self-appointed experts on the Internet have
caused many, many problems because of errors and misinformation. It is
better to do ones own research and due diligence and find out for
himself what the cause and solution is to any problem with his
installation. Some of the advice given on such websites is just plain
wrong. It's time we stop worship of the self-aggrandizing "experts" with
their pretty websites and stubborn opinions and start doing better
installations. The knee-jerk bonding and ferrite isolation panacea
prescriptions are getting a little old.

Apologies to the forum if this is appears to be a deviation from IC-7000
topics. The fundamental problem is widespread, and applies to all mobile
installations, including those with the IC-7000.

Respectfully.

Using a dummy load will not tell you if you're having RF current returning via your coax into the radio. I'd suggest grounding and a good supply of mix 31 ferrules will fix the problem.

I'm curious as to how you came to this solution. By suggesting grounding and bonding I gather you probably suspect stray RF as the root cause. Wouldn't running the device at full power into a dummy load be a quicker way to eliminate RF as the culprit? Failing this, the vehicle's charging system simply cannot handle the load.

Sorry if this has been covered before but I need some advice.

I am trying to use my 7k mobile with a turbo tuner and tar heel but am
running into problems when tx at 100 watts.

1) When at idle or even at speed my dash gauges will start to turn off when
I key up.

2) The radio will turn off when I key up.

My guess is that I am loading down the battery. I am using 10 ga directly
from the battery and have also tried a 65 ah fully charged standalone
battery. All rigged with powerpoles, with and without a rigrunner.

The problem goes away when I lower the tx power to about 55 watts. I am
driving a 2003 chevy silverado hd 4wd quad cab long bed and the antenna is
mounted to the 2" hitch receiver.

I have seen previous posts talking about how the 7k does not like less than
13.6 v.

This does not happen when inside off a power supply. I have not tried the
radio on my emergency battery but suspect I would see the same results.

I have not yet bonded the vehicle but that is on my list.

I bought the radio at hamcation in orlando in feb and I remember using it
most of the way back to atlanta with few problems.

Any suggestions?

Re: Mobile power or Common Mode Current?

I had a similar problem with "shutdown" -- ran ground braid from the antenna mount to a bolt on the lift gate, and from the mobile mount to a bolt inside the rear wheel compartment of the highlander. Added a couple of clamp-on toroids just because I had them. Problem solved. The combination of the IC-7000, Turbo Tuner and Little Tarheel II has given me 3 years of no-further problem daily use.

Re: [IC-7000] Mobile power

Your stated use of 10 gauge cable makes me think that perhaps you are getting too much voltage drop. In the late 1970's and 1980's when I was a local Civil Defense/Emergency Management Director, I ran two GE 100 watt 8 channel radios (one low band VHF and one high band VHF, Public Safety). These may have pulled a little more current than the IC7000's 22 amps full power as they were using tube finals, but they came equipped from the factory with a red power cable and a black power cable, each being at least a 6 gauge stranded and possibly a 4 gauge stranded. Check your input voltage at full power and see if it falls within the IC7000 specs of 13.8 vdc +/- 15%. Remember, both cables go directly to the battery and both are fused. I mounted my fuse blocks (all four of them) in the engine compartment near the battery. I used a second battery and a battery isolator to handle my radios and emergency lights/siren.

Re: [IC-7000] Mobile power

Jack Rucker <jackr1@...>
 

The dummy load is a good idea - but the symptoms are classic RFI.

If he had that poor a battery-alternator, he'd have been push-starting it.

I've been running mobile 50 years, including 36 amp key-down load on a 6V 36 HP VW. RFI is RFI.

When my HF loading coil is 3 inches from rear defroster, the dash defroster lamp comes on with each dot-dash, letting me know my 400W final is working OK. My alternate ball mount antenna, or just 100W, "cures" this problem. I have not tried to solve this one [except raising coil with higher mast = no RFI] - but a grounded shield on the back window may be the only way.

I ran a Collins KWM-2 for 2 weeks with no alternator in car, by push-starting, & charging each night. No blinking dash lights or gauges, unless headlights also on.

Every time I come across this, I scratch my head.

The text below is taken directly from the U.S. IC-7000 instruction
manual (page 148)

What is the significance of the '2-' and '1-' before the specified
powers? For example we know that the rig is supposed to deliver
100 Watts on HF and 6 meters, but what does 2-100 W mean?

Output power:

2–100 W (1.8–50 MHz bands)
2–50 W (144 MHz band)
2–35 W (430 MHz band)

AM

2–20 W (144 MHz band)

kj4bwo,

I had the same issue. Measure the voltage at the radio (carefully) on some HF freq when you are keyed down in FM, RTTY or CW if you have a key (SSB will require you to make a constant carrier into the mic). Preferably use a dummy load to reduce interference. I suspect that your voltage will be quite low <=12.5VDC due to the high amp draw requirements of the radio at 100W, even with the alternator assist. If that's the case your battery needs a good long charge from shore power or, if its the OG battery, its past it maybe past its effective life (6 years+) and requires replacement.

My guess is that I am loading down the battery. I am using 10 ga directly from the battery and have also tried a 65 ah fully charged standalone battery. All rigged with powerpoles, with and without a rigrunner.

The problem goes away when I lower the tx power to about 55 watts. I am driving a 2003 chevy silverado hd 4wd quad cab long bed and the antenna is mounted to the 2" hitch receiver.

I have seen previous posts talking about how the 7k does not like less than 13.6 v.

This does not happen when inside off a power supply. I have not tried the radio on my emergency battery but suspect I would see the same results.

I have not yet bonded the vehicle but that is on my list.

I bought the radio at hamcation in orlando in feb and I remember using it most of the way back to atlanta with few problems.

Any suggestions?

kj4bwo,

I had the same issue. Measure the voltage at the radio (carefully) on some HF freq when you are keyed down in FM, RTTY or CW if you have a key (SSB will require you to make a constant carrier into the mic). Preferably use a dummy load to reduce interference. I suspect that your voltage will be quite low <=12.5VDC due to the high amp draw requirements of the radio at 100W, even with the alternator assist. If that's the case your battery needs a good long charge from shore power or, if its the OG battery, its past it maybe past its effective life (6 years+) and requires replacement.

It seems as if you're having a case of Common Mode Current, or RF running around at will. You did mention not "Bonding" the vehicle, which can Contribute to your problem. I'd suggest you pay a visit to Alan's website www.K0BG.com

I always understood it as a range.

2-100 = 2 watts through 100 watts

Every time I come across this, I scratch my head.

The text below is taken directly from the U.S. IC-7000 instruction
manual (page 148)

What is the significance of the '2-' and '1-' before the specified
powers? For example we know that the rig is supposed to deliver
100 Watts on HF and 6 meters, but what does 2-100 W mean?


------------------------------
Output power:

SSB, CW, FM, RTTY
2–100 W (1.8–50 MHz bands)
2–50 W (144 MHz band)
2–35 W (430 MHz band)

AM
1–40 W (1.8–50 MHz bands)
2–20 W (144 MHz band)
2–14 W (430 MHz band

I assume the minimum power output you can get from the rig on most
bands/modes is 2 watts, the exception being AM on 160 to 6m, where the
minimum is 1 watt.

Or am I wrong?
I never thought of that angle... It seems logical :-)

Thankyou all for the replies
Thank you all for the replies, I feel silly now I asked, but to clarify I have only had the rig a few days,
and had never noticed the socket on the head.
I found the one on the back when setting up and
thought that was it :), hence the question, and I had never bothered to look underneath hihi.
I'm getting educated here, that's for sure.

A quick question of curiosity regarding the separation kit,
which I hope to acquire soon.
How does the microphone fit in to this set-up? Does another microphone
extension lead need to be added,
or is this part incorporated in the opc-1443 or 1444 separation cable?

I have an Icom IC-7000 radio setup that i bought over the course of the last 18 months or so that i've decided to sell. Regrettably i haven't really ever been able to use it for what i wanted to (HF) as my apartment living situation has proven too difficult.

Pictures here:
http://www.ebokeh.com/ic-7000 <http://www.ebokeh.com/ic-7000>

It's left my house only once in a padded case and is generally in like new condition. I've used it for about an hour a week for the last year on the local 2m nets at 5% power. It's in perfect operating condition. I've never once had a problem with it.

If you add a power-supply and antenna this should be everything you need to get on the air and start DX'ing. (computer control of the radio, external XLR mic capability, PTT switch, Z11 Auto tuner autotuner)

I've added "condition" ratings next to each item. On a scale of 1-10 how the equipment looks/functions. 10 would be mint condition, right out of the box. All cables are marked 8 on this scale just because they've been wrapped and sitting behind the radio for a year or so.

Everything works perfectly. This setup should provide many years of service

I'd like to sell it as a bundle - it's a good kit that'll get someone on the air right away, granted if you're looking for an IC-7000 for mobile use some of these extras probably won't appeal to you too much...

(looks like i forgot to take a picture of the C-IV cable, i'll try to get one up shortly - it's simply an 1/8" mono (TS) -> DB-9, well made - about 3' in length)

Here's a list of all of the parts:
- IC-7000 Radio in factory box with instructions (S/N: 05076xx) and included accessories (HM-151 handset mic) (Condition 9)
- 2x IC-7000 Power cable with soldered Anderson PowerPoles (Original plus extra)
- Handle kit is installed on the radio (MB-106) (Condition: 9)
- 3rd party CI-V cable. I used HRD to control the radio, works perfectly
- LDG Z11 Pro Autotuner w/ icom cable (bought new, used only a couple of times, Condition: 10)
- Heil 8pin -> XLR+PTT for Icom (I used a Shure SM58 and got great sound), any good mic should work well.
- Heil Handswitch for PTT (Condition:9)
- RJ-45 -> 8 pin heil adapter for XLR mic

Please email me directly for additional details/questions if you're interested
