Tnx for the reply

We want to transmit outbound from the I gate so we will need a PTT circuit.
Do you have any info on a ptt sct?

There are email servers on the igate system but the format is un clear to

First of all, I would suggest you ditch the baofeng and usb sound card in
favor of an RTL-SDR ($20 on amazon).   there are a ton of instructions
online on how to set up the RPi + RTL igate, and Andrew Rich has created a
script that does it all for you.   Really a much simpler setup than using
an actual radio and soundcard interface.

As to your questions, not sure what you mean by "email server"?   There is
no email server involved with an igate.    Not sure what you mean by "up
the radio".   Do you mean "uplink"?   If that's the case, you need to
fabricate a PTT circuit to key up the radio.   Vox is an alternative, but I
did some tests like that and got really bad results (vox would keep the
radio keyed up for many seconds after Tx'ing a packet, thus missing any
digipeats or auto *acks or responses.
