Re: Separation cable

Ahmad Eddie Mobasheri
 

Hi to all!
I am wondering how can I get hands on one separation cable ( Icom Ic-opc-1443, 3.5m). Even a working second hand will do me!
I am in Auckland, New Zealand.
Kind regards
Eddie Mobasheri

Undoubtedly, everyone is aware of

F-150, the computer decides how much power the alternator
puts out. Gone are the days of constant 13.7 Volts. The
problem is, I can't rely on the input voltage from one
transmission to the next. Has anyone resolved this problem?
I've been looking at a constant-voltage DC power
conditioner, but can't find anything. Any ideas?

I did the exact same thing with the 1960 Chevy.  Installed a second battery, but connected both of them to the alternator when the car was running.  No Diode drop.  I had purchased a 100 AMP alternator from the junk yard to charge both batteries.  When the engine was off, I could use the accessory battery as much as I wanted, and still be able to start the car.  I also had a heavy duty starting relay, that I could energize connecting both batteries together to start the car on very cold mornings.  I remember it being 26 below zero in Iowa and my car was the only one that ould start.  I spent the rest of the day, giving people jump starts.

Charge both while driving, tap the fuse block for a source that the ignition key drops a relay to disconnect the “radio” battery, when stopped.
There are also automatic diode wigits for not letting current flow from the “truck” battery to the radio.
Run the radio until the second battery dies, always start the truck and drive away.

Been there, done it. (Don’t ask why)…….

ALC pegs on SSB but no output, too high power output on others

 

My "fixed" IC7000 has a transmit problem. 
It seems to be OK on receive but on SSB the ALC pegs with even the least audio and it puts out no RF power.
On RTTY, CW, etc it seems to put out too mucheap power.
Any thoughts as to where to start looking?
I have replaced the ribbon cables from the main board to the PA board as the old ones cracked while working on the "Click Click" problem. 


Re: IC7000 Intermittently Deaf on 80 Meters when Cold

 

I will check when I get back to the QTH but I believe that the CPU turns on different "lines" from the main board to the PA board and they are routed through the ribbon cables in the back. 
Sometimes these are temperature sensitive. 
I will look when I get a chance to see if this could be the case.

I've got an MFJ unit which maintains a supply at a constant 13.6. I can't remember the model number at the moment as I'm not at home, but it works well.

Any thoughts????

I have my 7000 mounted in my car. I have noticed that when the temperature is below freezing, my 7000 is deaf on 80 meters when I first turn it on. I have also noticed that the receive kicks right in with normal sensitivity at 4.000.000 MHz. If I tune one step lower, receive cuts out. If I tune back up to 4.000.000 MHz receive pops back in. This condition goes away once the interior of the car warms up a bit.

My question to the group is: Is there something in the receive chain that switches right at 4.000.000 MHz? Perhaps a sealed BPF relay that has become unsealed and gotten moisture inside of it???

The data port on the 7000 is the one you want to use. The other connector keeps the mike hot while the data port mutes the mike.

In speaking to Randy at Timewave they also have a cable using the data port and not the ACC. Since no one has answered me on three reflectors, I am guessing no one is using the Navigator/7000 and PW-1 at the same time the IC-7800 is hooked to the PW-1?

Bill,
You'll need to make a splitter cable to get the amp keying output from the IC-7000.

Hi Steve,
Thanks and maybe you can help further. I have the Navigator hooked to my IC-7000. My 7800 is hooked to the PW-1. I want to add the PW-1 to the 7000 but the ACC port is used by the Navigator. I see no diagrams or drawings to help. It appears to be a 7000 question because I received no replies on the Navigator group hi.

Re: IC-7000 and IC-7800 to PW-1 Cable

Hi Bill,

then it could be a little tough. You would need a CIV splitter. The lines on the ACC cable would also need to be split and in some cases you may not be able to tie them all directly together without a buffer.

Re: Icom 7000 with SDR Play

From the MFJ 1708SDR switch manual…

 

TECHNICAL ASSISTANCE

If you have any problem with this unit first check the appropriate section of this

manual. If the manual does not reference your problem or your problem is not

solved by reading the manual you may call MFJ Technical Service at 662-323-

0549 or the MFJ Factory at 662-323-5869. You will be best helped if you have

your unit, manual and all information on your station handy so you can answer

any questions the technicians may ask.

You can also send questions by mail to MFJ Enterprises, Inc., 300 Industrial

Park Road, Starkville, MS 39759; by Facsimile to 662-323-6551; or by email to

techinfo@.... Send a complete description of your problem, an

explanation of exactly how you are using your unit, and a complete description

of your station.

 

The switch can use RF sensing to toggle the switch but you may want to use the IC-7000’s rear panel external PTT output like used with a linear amplifier instead. That will usually switch before RF is present and will protect the SDR better.

Anyone use this combination with an MFJ 1708 antenna switch.

Thoughts?  Is there a setup configuration?

Re: IC-7000 and IC-7800 to PW-1 Cable

Steve Draper
 

Bill,

You will need the OPC-599 cable adapter which converts the 13 pin accessory plug to the normal 7 and 8 pin connections. Then you can use a normal accessory cable between the adapter and PW-1. You will also need a CIV cable (1/8 inch) of course.

Re: IC-7000 RF power inaccurate on display

k0fni k0fni <k0fni@...>
 

The toroid in the output section may be faulty, it feeds back through the ALC circuitry and actually controls the output reading. It is very hard to get used to but start with the power at near 5% level with wattmeter monitor the output and then adjust it slowly upward and see if that helps until you get to approx. 80 watts output.
