Kenwood TH-D75 APRS experiment

A walk in the city

I took a short trip to the city with the aim of conducting a brief APRS test using my Kenwood TH-D75. The test aimed to map the coverage areas of the Braga digipeater, CQ0PBR, installed on Mount Santa Marta, at an elevation of 562m ASL. Knowing in advance that the antenna was not yet in its final location due to some technical constraints, I was aware that in the more obstructed and lower areas, without a line of sight to the digi, it would be very difficult for my packets to be repeated.

VE2ZDX Toolkit

A platform that helps amateur radio operators document and preserve their on-air experiences

I got an email from VE2ZDX, one of my latest POTA QSOs. I was surprised by how interesting this is. The subject of the email was “CT1ETE, watch your QSOs from the other side!”. Then, there’s a link that says “Watch the videos!”. Ofc that the first thing I did was to click on the link (the source was legit to me!). I was redirected to a page where there’s an embedded Youtube video with the recording of VE2ZDX’s QSOs, and that pointed to the time of our POTA contact.
