Anyone know what value the Garmin baud rate resistor is for a GPS antenna? It's normally an orange wire with a piece of black heatshrink in the middle, it's to drop the comm speed from 38400 to 4800 which suits most plotters.
I was contemplating buying a later Garmin GPS but its native baud rate is 38400 without the resistor and as it's an 'open box' as new antenna there is no resistor with it. As you say a Garmin one is probably half a limb for 0.04p resistor. I'll have a think, I guess it'll 100 or 160 ohm and it wouldn't be difficult to try a few.
