Doesn't exist. Mobile VHF duplexers will not work below ~2.5 MHz split.
Best you're going to do size-wise is the Sinclair Q2220 series, but the
spec is only 70 dB of isolation, not enough for a 600 kHz split. The one I
had had adjustable loops, so I was able to get ~90 dB out of it after
taking an extra 1 dB loss hit (2 to 2.5 dB total loss IIRC & the notches
are VERY narrow). At 28 pounds, not exactly portable either but will fit
in a car trunk nicely.
