Subject: Alinco DJ580.MOD de Tony ke3ed @ k3oiw. Hello all, I have seen several msgs requesting details on how to connect a TNC to the ALINCO DJ580 h/held,so heres how i did it !!! (after immense fiddling,these are the connections used for 6 months) tip .. ..ring ....body . . . . . .= O [] ======== 3.5mm plug . . .= rx audio ...... . . ..n/c ..gnd = O [] ======== 2.5mm plug : = TX audio......: --- : : 10 k resistor : : --- : TX ...........: so,the only connection to the 2.5mm plug is to the TIP!!!! tip=TX audio TX is to tip via 10k resistor. "sleeve & ring" NO CONNECTIONS RX audio=TIP of 3.5mm,sleeve NO CONNECTION,body=gnd Please let me know if this is of any use to you. don't forget- DO NOT insert/remove plugs while the rig or tnc is on !! 73,Paul G1XUL--HOMEBBS=GB7BAD--AMIGA/AMIPAC--TINY2--DJ580--FREQ 433.675
