Never heard of it. Photo? Do you have an operating manual?

Connect ALC, PTT and you are good.

yes. I have the basic manual but it is of no help at all.

Hi. I have tried that and pressed the ptt but the amp did not start. The amp has been used on my kenwood radio and the is working fine.

Is the amp keyed by RF or the PTT keyline?

I think it is keyed on the PTT line. The manual says
3. CONTROL VOLTAGE is 12 Volts, used for pulling in the TX/RX relay and gives the LED the control condition of the amplifier.

 

[Richard01]

the manual says
The maximum signal level of the [SEND] jack is 16 V/0.5 A DC. Use an external unit if your non-Icom linear amplifier requires
a control voltage and/or current greater than specified.
• The ALC input level must be in the range 0 to –4 V. The transceiver does not accept a positive voltage. Non-matched ALC
and RF power settings could overheat or damage the linear amplifier.
• When using a linear amplifier such as the IC-PW1 or IC-PW1EURO, set the RF POWER in the Multi-function menu to keep
the ALC meter in the red zone.

LSee page 3-11 for details on the ALC zone

What is it you don't understand about it? If you ground the relay jack on the amp, it should energize the amp relay. To do this with the 7300, you use pin 3 of the 13 pin DIN ACC jack, or the SEND jack.

From what you posted, the amp has a 12v relay, so it *should* work without a buffer, but I am not familiar with your amp. I have never seen it or any schematic/manual, so it's on you to do what you do.

In your amp flip switches to TX and ON and short PTT socket. Is it going to TX?

A patch cord with a RCA (phono) plug male on each end plugs into the radio's
"Send" jack, the amplifier's relay jack at the other end. Likewise for the ALC.

Thanks for your help. The info I rceived from the cable supplier saaid I just had to plug in the send cable and the alc cable and it would work but it did not.I will keep plugging away with it. Thaanks

Hi. I did get 2 RCA cables from a radio shop one for the ptt/send and one for the ALC. i have plugged both cables in and switched the amp from standby to operate and pressed the ptt but the amp does not start up. I did connect the amp back up to my old kenwood 990 and the amp is working fine.
