PBeacon PHG settings

 

Good evening all.
?
When setting the parameters in the direwolf.conf file for PBeacon, specifically the PHG, is the antenna gain specified in dBi or dBd?
?
Thanks and 73

?
The direwolf User Guide, found here? , specifies "dBi" for PHG antenna gain.
?
The confusion arises because there is a lot of outdated documentation still hanging around on the Internet.
?
The original APRS protocol specification, affectionately known as APRS101.pdf,? said "dB" for gain.?
WB4APR compiled more than 20 years of corrections, clarifications, and new features since that time.
Clarifying that antenna gain is in "dBi" is among those notes.
?
You can find a compilation of the original document with decades of updates merged in here:?

?
PHG is discussed in detail in chapter 7 of APRS12c.pdf.? Your feedback is welcome if anything is not clear.

Thanks John.

The user guide is where I ended up finding my answer....? Not sure why I didn't see it earlier before asking.? ?Lots of sources online simply say dB as you pointed out.? ?You are correct that a lot of the information out there is outdated.?

I will take a look at the other information you sent a well.?

Thanks again.?
