DATA pins: 1 DATA IN, 2 GND, 3 PTTP, 4 DATA OUT, 5 AF OUT, 6 SQ

Setup sides for voice and data:

Hey Frank –
On page 83 of the manual it covers setting the data band. You will want to select B band. You will see a “D” on the right side of the rig. This confirms that the audio in and out of the 6 pin will be to THAT side of the radio. See this pic: https://planetkris.com/gallery/KI6IUC_mobile/DSC00728

Then I would tune up to a channel down in the digital mode band plan – I use 144.800. Grab an HT and see if you can hear packets from the radio. When you get that tested – then I set it up for 144.390.

Hope you get it sorted – Kris
