I ordered a ARB 704 which will here next.For those that don't know the IC2kl is a 2 or 3 piece
amp.,power Supply, and the third is 500watt autotuner. The heavy black cord I assume 6 connection fits nothing on the 3 pieces so I AGAIN assume some way into an Icon. I have the manuals but says nothing on any other kinds of radios
any help would be appreciated

Hi Byron, it is all relatively simple..

You don't need the ARB 704 interface as the IC-2kL has logic circuitry that does not draw a lot of current through the transciever relay. So this can be coupled directly to the TS-2000.
If you look on page 94 of the TS-2000 manual, they tell you how to connect the wires to the 7 pin DIN plug ,and how to activate the linear keying in the menu.
So on the 7 pin din plug, Pin 2 is common (shield) for the PTT shielded cable, and Pin 4 is the centre of the same cable and PTT for the amp.  The other side of this cable will go to a RCA plug, and this will plug into the PTT / TX RCA socket on the back of the IC-2KL.
The ALC cable is connected to pin 6 of the 7 pin DIN plug, and the shield is connected to the 7 pin din plug case, the shiny bit with two halves that clip together.
The other end of this cable goes to a RCA plug, that pugs into the ALC socket at the back of the amplifier.
YOU MUST USE ALC WITH THIS AMP--and ADJUST IT CORRECTLY FOR MAX 500w AT THE BACK OF THE IC-2KL..
The IC-2KL supply will plug into the back of the linear, the tuner I think has its' own supply.
The coax patch cords from the rig will go: Rig ant. connector to IC2KL input , From Output to Tuner Input, From tuner Output to whatever antenna

I forgot to mention:  As with any amp, this one in particular can be easily overdriven!.. So when switching in the amp, reduce your drive / mic. gain to less than 20w output--you can always bring it up slighly again whilst watching the alc meter--this is why the amp ALC must be connected!..   Those transistors are expesive--so look after them.
Also, you will need to switch the band switch manually, as the band selection on the IC-2kl is voltage dependant--don't forget to switch bands.

CHECK what voltage the IC-2KL pSU has been set for 110V or 220V?.. IF you have 220V then that would be a better option--IF your PSU can be set for 220v.

I run my IC-2KL with my TS-850S and boy!--they work well together.. The IC2KL fan is just a bit TOO noisy!..

Now it would be nice if he would pay for the Amp, power supply and AT-500 tuner that he bought from me and then did a chargeback or he could just send it back to me. Nice to have $1300.00 worth and not pay for it.
