Airpal SSB Transceiver

At last after a long gap of time we have been able to complete the Airpal Dual Band SSB Transceiver.

We have placed an order for the Airpal PCB set of Exciter And BFO VFO with JLC PCB. Once the PCB arrive we shall upload the pictures,

We shall be adding a download link for the complete Airpal Manual With BFO VFO And Firmware in the download section very soon.  The printed circuit boards of Airpal are arriving from JLC PCB very soon. The work of kitting the Airpal has started, hopefully the Airpal Kit sale is to start very soon.  The pre-booking of Airpal to start soon.Thanks and we shall keep you posted for more news on Airpal.
