If you put the SWR meter at the antenna, you won't identify any defects in the cable.

Whilst marinetraffic seems to have the highest number of feeding receivers, the servers are painfully bad at offering duff and regurgitated data. By comparison, vesselfinder updates faster and doesn't store old positions. Also worth checking when using a single antenna is the tuned frequency. A...

And here is a simple comparison between class B SOTDMA and CSTDMA SOTDMA vs CSDTMA

Just spotted this thread as a result of @Star-Lord linking my post elsewhere. The outcome of that incident was he lost a leg from the knee down, well he'd actually lost it before he called for help. He is back fishing complete with false leg and with a few extra belt guards in the engine room...

@Happilyoverforty If you want to PM me a full list of what you've already got, I'll spec a current equivalent system with sensible enhancements.

Just a technical point, VHF radios feature DSC, digital selective calling which in corporates a distress button. GMDSS is a complete safety system used on commercial vessels that happens to incorporate DSC VHF's. Global Maritime Distress and Safety System - Wikipedia As mentioned by others...

No get around. Cables and software only supplied to dealers as the same kit also allows frequency programming.

I hope your memory is better than mine! :ROFLMAO::ROFLMAO:

Oh, if you can program Raspberry PI, there is an 8 channel 4-20mA interface available for those, Pi-SPi-8AI Raspberry Pi Analog Input (4 - 20 mA) Interface and a 7" touchscreen Official Raspberry Pi 7" Touchscreen Display Cheap solution but you'd need to be able to write the software for it.

I'm not suggesting it is the solution I would use, just that it would do what you would need. It is probably the only device on the market that would put 4-20mA on to NMEA2000, the fact it does 6 channels is a bonus! Your primary problem is they have used 4-20mA senders, these are not generally...

simple answer is, no it won't work. NASA log transducer has a reed switch in it which is operated as the magnets in the paddle wheel passes over. 2 wire switching. ST300 has a hall effect sensor in it which creates a voltage pulse as the magnet passes. Requires a 5v feed and 3 wires. either...

Maretron CLM100 does 6 x 4-20ma inputs onto NMEA2000 Maretron - Current Loop Monitor (CLM100)

With how little price differential there is between an AIS receiver and an entry level transceiver, fitting a receiver is a waste of money. Just think how blank the screen would be if everyone only fitted receivers!

there is 2 modes, proportional and bang-bang. 2.5vdc is the mid voltage of the joystick when it is released and centered. In proportional mode When the input is equal to 2.5vdc, the rudder is central. Increase or decrease the volts and the rudder moves proportionally to that position and stops...

you actually stated "No idea how it works. " I've clarified, how it works!
