I decided summer is finally over and forest season for #OpenStreetMap is on.
I was so wrong. Under constant sorties of mosquitos and barrage of fallen acorns I managed to survey 20km.

Also tried my #th-d75 first time on the field for #APRS. Some packets made it better than I expected with relatively distant digis. Sad reality, stock antenna is not that good. So I attached my crooked #DIY signalstick knock off for instant performance boost. Able to send an email with #winlink and several packets on high peaks. @alper I don't think the stock D75 antenna is any worse than any other stock HT antenna, but I agree with you completely - for packet operation, the performance goes way up with a longer antenna. It's quite a shocking difference. #HamRadio handheld VHF/UHF transceivers typically sport antennas roughly 8 cm long. Those have two main properties: - Their small size makes it easy to carry the handheld around or stow it. - They are a disaster performancewise. Especially on transmit, they don't even start to let you experience what your handheld is really capable of. Antennas abt 30 cm long are a LOT better electrically. 𧡠Also, it is fun to occasionally use a handheld with a serious station antenna. This is exactly why I always change the antenna connector to BNC for any HT I own/buy, first. Operating the HT on the station antenna is a lot of fun, sometimes. And I only buy BNC antennas for these HTs, too. Personal opinion: I love the Diamond RHF-10 for being extremely short/convenient for local repeater operation. But I also love the Diamond RH-519 for having a much, much better reach and still being short and thin. Comet usually offers mostly good knockoffs, btw. @stefanfendt @dj3ei @alper yup, I learned to use BNC adapters from the good folks on here. @gustav I mostly map forests where foliage obstruct sat pic based mapping. I obtained a Ublox f9p receiver which gives me unparalleled accuracy under the trees. So I can map tracks, paths water sources or anything that relates outdoor. I have been doing this for a while but area is wide enough to be a long journey. This is where I map. Location: geo:41.17082,28.91528?z=14 |
All that walk is for an area of 4 km2. The rampant lumber industry in this historic #forest is creating all these tracks. They leave them afterwards and it never heals up.
