REDUCED: AEA PK-2232 TNC Setup: AEA /Timewave calls the DSP-2232 “The Cadillac and Corvette of data controllers.” Work satellites, HF, VHF, and Gateway between HF and VHF with 2 ports.
Best performing TNC I’ve had, with the Mode and speed on the Display, and being able to ‘read the mail’ on the Display. However, just too big to fit on my Desk with 4 Radios, so I’ve had to go back to a smaller TNC.

in excellent condition and works as it should. As with any equipment of this age it is being sold AS IS with no Returns.
