—Pin 3 (HSEND) is normally used for PTT on HF/50 MHz. Pulling this pin low will enable transmit on HF/50 MHz. It will not enable transmit on VHF/UHF.
—Pin 7 (VSEND) is normally used for PTT on VHF/UHF. It works exactly the same as pin 3, but for 144/430 MHz only.
This arrangement actually makes sense. In most applications (particularly mobile), you will use a different antenna for HF/50 MHz than for UHF/VHF. Additionally, the output drivers in the IC-7000 are separate for HF/50 MHz and UHF/VHF.
Now, you can change this behavior in the “Set” menu. What is shown above is the default. Look at page 131 of the manual, and you will see that, under the “Set” menu, you can change the parameter “VSEND Select” to “Off.” In this configuration the HSEND pin on the ACC jack will enable transmit (PTT) on ALL bands. This may be what you want.
