Excellent. I was planning on doing the same thing as I ordered a couple of spare GPS' when I did my 536HP.

Thank you, sir! I can make a patch cable for my RS232 Garmin puck if I decide to get one of these units. It currently feeds my 536HP and a Kenwood 700 APRS rig and works great with both.It's NMEA.

So forgive me @mancow but you're using an RJ11 which (as you show) has 6 positions, but only 2 conductors. How are you getting all four lines (3.3v, TX, RX, and GND) out of the radio and to the GPS module?
Hello,
I wired up the Adafruit Ultimate GPS module yesterday and could not figure out how to test it. I thought "Autolocate" was connected with the GPS, but it is not. I should have read the manual! I really like the module and using the 1220 battery option results in very short time from power-up to first position fix. The sensitivity of the module allows me to use it on the top floor of a wood frame building with a rubber/wood roof. It is important that the module is receiving GPS satellites and sending a valid position. The module will send position information as long as it is powered up, but it will indicate the position is not valid when not receiving GPS satellites.
This morning I had time to sit down and figure stuff out. The lack of a status display does not help. I decided to use a RJ-11 jack on the finished unit, so I can just use a telephone cord between the GPS and the SDS-200. I soldered the 9 pin header and wired things up using the RJ-11 jack to a 4 pin connector.
I noticed the clock on the SDS-200 was one hour early before I started testing again. I thought I had set it to the correct time yesterday. I noticed the time zone was set to -6.0 instead of -5.0, so I wondered if the GPS set the clock yesterday. I changed the time zone to -5.0.
I also figured out a way to test it. I have a predefined location in my configuration for Plymouth Meeting in PA, so I set that as the location. The scanner loaded NJ, PA, etc..., and started scanning. I turned off the scanner and turned it on again. It loaded and scanned for Plymouth Meeting. I plugged in the GPS and got a fix in a few seconds. After about 10 seconds or so, the scanner loaded my local area. Success! I also think you can use the Save Location menu item and see what position is stored.
The time on the SDS-200 did not changed right away, but I noticed it was the correct time about 20-30 minutes later. So the scanner will use the GPS to set the clock.
