Re: IC-7000 to MFJ-4416c and HSEND?

 

Hi Michael

I had a 4416 in my crew cab truck hooked to my 7K with the radio body, booster box, and independent battery 100A AGM (much less noise)? in a radio box I made in my locked?canopy, and the control heads for both at the driver's seat.?
To spare the radio battery I went into the control head of MFJ 4416 and installed two small micro switches on the left side to shut off power to the control head and to the control unit in the rear. The power booster would not output power unless both the (power booster always on the red button ) was pushed and both of the micro switches were on.?
Having the two switches I could see the difference in voltage between no booster and with the booster.? ?I added a third micro switch to the right side to control the lights in the meters so they were not always on.? (saving battery I hoped).??

?It has been working for many years till the truck was retired and I plan to install the setup in my Ford Edge under the rear seat with the control heads on an? 8" drawer slide, out of sight until needed.? The only thing that will be seen is my dual-band antenna on the roof and the HF antenna mount behind the rear tire on the passenger side.

Good luck,? Hope you get your working,

IC-7000 to MFJ-4416c and HSEND?

 

Hello All,?
I want to connect my 7000 to an MFJ-4416C voltage booster's keying circuit so I don't have to leave the booster ON - It generates rolling switching noise when just left on.? Anywho, my other radios have a SEND RCA plug that goes to ground to key an amp, but the 7000 has an HSEND and the manual shows it as an input and output, so I don't want to do something stupid and let the smoke out.
?
I would have thought all I needed to do would be connect the HSEND to either pin 1 or 2 on the 4416, but looking for confirmation.? I don't care to use the VSEND for anything because this is my HF mobile, and I've got a separate VHF/UHF rig.
?
Any suggestions, confirmations, or cautions welcome.

Hi Reg

Once the burnt area has been cleaned you can get an idea of ??how to proceed. I'll tell you how I did it :

If there are no SMD components in the area (or even a few of them) but only discrete ones, you can use a little rasp to make a nice hole (hi) and remove the entire burned part of the PCB.

Then use a piece of copper-plated fiberglass on one side, make holes to place the discrete components (the coil for example); the copper side goes towards the drain of the mosfet so as to have a strong and stable soldering; basically rebuild all the links that were blown away.

It may seem unprofessional but I assure you that between the abundant welds and the metal screen the job will also be well done aesthetically and above all you will recover a radio that you cannot use on VHF

Once you have made all the connections and verified the connections, redo the bias and try everything again. With this technique (shaping a piece of copper PCB in the hole) I repaired 2 boards, one of an ICOM-PW1 and a final stage of an ICOM-775, they have never given more problems. It's an attempt you can make.

Let us know about your repair.

73s, Pasquale IW0HEX

Hi

the situation is very hard !

On solder side I think there is an opportunity but I have no idea with the damage in other side !

You should to clean the other side well and to do some other photos to understand if there is a space to fix ! If the area is full of SMDs component, it's very hard to fix, the situation is very very difficult.

Please, if you can of course, try to do other photos of other side (side with coil) ; before clean well . Thanks

Hi Paul
Just thinking, I would even consider a faulty board as long as its not burnt up. Mine burnt at the junction of Q501 and L531. There was a dry joint on L531 and it burnt a hole in the board. I would be able to get a working board out of the two of them. Just hoping
Many thanks, Reg
