11. Programming the PF button for tune function (change radio to CW mode @ low power 10W) 1.Press [Menu/FLock], turn MULTI knob to select Menu #48 2.Press [ ˄ / ˅ ] to select “67” 3.Press [Menu/F.Lock] to store setting and exit 4.To tune press the PF button 5.To exit tuning press the PF button

12. AFMARS 2015 NE Div Conference Purpose of the “Y” cable and how it works (from RMS Express Help) Eliminate the A/B switch To connect multiple TNCs or sound card interfaces to a single radio Eliminate swapping cables from the TNC or sound card to the radio

13. AFMARS 2015 NE Div Conference Simple resistive “mixer”, partially isolates each TNC low impedance output from the others PTT signals from the TNCs are essentially a relay or the open collector of a transistor Audio out of the radio can safely drive the TNC audio inputs without the need for resistor isolation Purpose of the “Y” cable and how it works (cont.)
