I installed one in a friends RV-8. It was easy and strait forward. The GDL82 will work with other mode C transponders as well.
Danny, I will soon be mounting a GDL-82 in an RV-8. Where did you mount the box itself and where did you mount the GPS antenna?

Thanks

From the GTX330 installation manual:
GTX 330 Power Consumption: 11-33VDC, 22 watts typical, 45 watts maximum
And...
GTX 330 Weight, installed with rack and connectors: 4.2lbs

By contrast (and I offer this only as one point of comparison, there are lots of other good choices available on the market these days)
Trig TT22 power consumption: 11-33VDC, typical 6 watts @ 14V
Trig TT22 weight: 0.77lbs including mounting tray

I知 getting close to ordering a GDL82 to complement my GTX 327 which is currently about 6 years old. I知 assuming (?) that it値l require a software upgrade. I haven稚 yet tracked down what software version is required. Any help would be appreciated.

You might want to check with an avionics shop or Garmin. I just installed a GTX-327 that is at least that old, maybe older. I asked the local avionics shop if it needed a software update, he asked for the serial number and got back to me that it didn't need an update. I was happy since I was told the only way to get it updated was to send it to Garmin, through one of their dealers, and pay the flat rate for service.

Hello Jim,

This posting for transponder updates at Oshkosh 2018 explains the latest software versions for the GTX 327.
http://www.vansairforce.com/communit...d.php?t=162400

Garmin dealers can quickly update the software, when needed. The transponder does not have to come back to Garmin.

Let us know if you have additional questions.

Thanks,
Steve

Good to know, I was obviously misinformed.
