[TG] E80 plotter with AIS 700

Hello nachothecat,

Your VSWR is 1.6, or 16? 1.6 is improbably low (possible but unlikely), whilst 16 is that'll-never-work high (see the 'Reflected Power %' column of the table half-way down http://www.antenna-theory.com/definitions/vswr.php for example.) You're seeing that VSWR in ProAIS2 over a USB connection from the AIS, or with a VSWR meter?
If you've used another *AIS-tuned* antenna, that's reasonably sensitive at ~162MHz where AIS operates (many VHF antennas are great at 156MHz / Channel 16, poor at 162MHz) with completely new cabling and have the same result, I'd get the AIS checked by your local Raymarine service dealer or centre.

No, I'm sorry to say that the E80 is too old to switch Silent Mode on AIS700.

Regards,
Tom
