Ben BrunzelFor my 50th unique Park activation on <a href="https://norden.social/tags/ParksOnTheAir" class="mention hashtag" rel="nofollow noopener" target="_blank">#ParksOnTheAir</a> I picked out a very special location. IE-0145 is located on the shore of Ireland next to the Hook lighthouse. The windy coast and the rough sea made this activation an extraordinary nature experience.As EI/DL2XU I worked 16 stations across Europe as well as one park to park to New Jersey.I used the <a href="https://norden.social/tags/QMX" class="mention hashtag" rel="nofollow noopener" target="_blank">#QMX</a> <a href="https://norden.social/tags/QRP" class="mention hashtag" rel="nofollow noopener" target="_blank">#QRP</a> transceiver with my linked dipole antenna.

AWESOME morning fun. Rocky Squirrel is back. No sightings or rumblings of "The Moose" but I thought I saw "Boris and Natasha" sneaking amongst the trees.

JeffGI did more hf <a href="https://mastodon.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> in one day than I think I did in the last year, or two. Now I have to figure out how to log <a href="https://mastodon.social/tags/pota" class="mention hashtag" rel="nofollow noopener" target="_blank">#pota</a> contacts.

Søren KjærsgaardOccasionally it can be a good idea to add an in-line diode to protect a power supply used to charge a battery.You want the resulting voltage drop as low as possible which calls for a high-power Schottky diode. The STM STPS5L60 is a 60V diode, rated at maximum 5A continuously. As I’ll be charging at maximum 3A, I decided to test the voltage drop and resulting case temperature at that load.I measured a 0.38V drop, resulting in about 1.15W dissipated - not bad 😃The outer case temperature rose to about 57C which is fully acceptable and way below the diodes limits. And it’s touchable as well, which is nice. So, charging a LiFePO4 battery for my <a href="https://techhub.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://techhub.social/tags/SOTA" class="mention hashtag" rel="nofollow noopener" target="_blank">#SOTA</a> and <a href="https://techhub.social/tags/POTA" class="mention hashtag" rel="nofollow noopener" target="_blank">#POTA</a> operations, I’ll set the supply to 15V, limit the current to 3A, and the battery’s built in BMS controller will handle the rest, easy! 👌🏼🙂For the record, I always keep an eye on it when charging and I usually reduce the current by the end of the charge cycle ☝🏼<a href="https://techhub.social/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronics</a> <a href="https://techhub.social/tags/electronicsengineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#electronicsengineering</a> <a href="https://techhub.social/tags/hamr" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamr</a> <a href="https://techhub.social/tags/testandmeasurement" class="mention hashtag" rel="nofollow noopener" target="_blank">#testandmeasurement</a> <a href="https://techhub.social/tags/rfengineer" class="mention hashtag" rel="nofollow noopener" target="_blank">#rfengineer</a>

Simon DC6ST<a href="https://mastodon.radio/@vk6flab" class="u-url mention">@vk6flab</a> <a href="https://mastodon.social/@abortretryfail" class="u-url mention">@abortretryfail</a> Yeah, in the meantime it was explained to me by <a href="https://mastodon.hams.social/@Geojoek" class="u-url mention">@Geojoek</a> that in the US not all license classes can use the entirety of the 40 and 80 meter bands, leaving just a bit or even no overlap between regions for some operators. That came out of left field for me. Since most Region 2 <a href="https://mastodon.radio/tags/POTA" class="mention hashtag" rel="tag">#POTA</a> <a href="https://mastodon.radio/tags/SOTA" class="mention hashtag" rel="tag">#SOTA</a> etc. activators are from the US, that explains my observation Re North America. There's simply not enough free frequencies for DX.

Simon DC6STIf you're using 40m or 80m, please remember the 40m band ends at 7200 kHz and the 80m band ends at 3800/3900 kHz in Region 1/3.Most North American "On The Air" award spots for <a href="https://mastodon.radio/tags/POTA" class="mention hashtag" rel="tag">#POTA</a> <a href="https://mastodon.radio/tags/SOTA" class="mention hashtag" rel="tag">#SOTA</a> <a href="https://mastodon.radio/tags/COTA" class="mention hashtag" rel="tag">#COTA</a> <a href="https://mastodon.radio/tags/WWFF" class="mention hashtag" rel="tag">#WWFF</a> etc. I see on 40m are between 7200-7300 kHz and missing out on potential <a href="https://mastodon.radio/tags/DX" class="mention hashtag" rel="tag">#DX</a> contacts.

KFO̸UNKI always forget about RBN. I tried to activate a couple days ago and 40m was really bad, while 20m was .. existing. It's really nice seeing later that I was really getting out with CW on a QRP radio and 40m EFHW, even though I only got 8 contacts before being run off by mosquitos!I'm really excited to see what I can do on a good day, and I'm itching to try the ZM-2 I picked up. I really don't like being stuck on 1 or 2 bands! 😅 <a href="https://mastodon.hams.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://mastodon.hams.social/tags/pota" class="mention hashtag" rel="nofollow noopener" target="_blank">#pota</a>

Michael VE3WMBToday is the last full day of our trip to VE9 so I decided that I would try to finish off with a POTA "twofer", in spite of the poor band conditions. I activated CA-5239 and CA-6435 an historic Courthouse and Gaol (jail) that are located on the same grounds in Saint Andrews, NB. In spite of an early start I only worked 6 CW stations, but managed to save the day with an additional 11 FT8 contacts. It was an absolutely gorgeous morning to be out playing radio. <a href="https://mastodon.radio/tags/pota" class="mention hashtag" rel="tag">#pota</a> <a href="https://mastodon.radio/tags/qrp" class="mention hashtag" rel="tag">#qrp</a> <a href="https://mastodon.radio/tags/ft8" class="mention hashtag" rel="tag">#ft8</a> de VA2NB/VE9

Stu GottOne <a href="https://gott.social/tags/morse" class="mention hashtag" rel="nofollow noopener" target="_blank">#morse</a> resource I found helpful for prepping for my first <a href="https://gott.social/tags/POTA" class="mention hashtag" rel="nofollow noopener" target="_blank">#POTA</a> activation was <a href="https://morsewalker.com/" rel="nofollow noopener" translate="no" target="_blank">https://morsewalker.com/</a>The neat feature that sets this site apart from other practice environments is its simulated pileups. When I encountered pileups in the real world, I didn't even blink--I just took it in stride and pulled out as much of one callsign as I could and asked for a fill.Between QSB and varied QSO speeds it's decently realistic. Of course it lacks the mass confusion of a real activation...<a href="https://gott.social/tags/CW" class="mention hashtag" rel="nofollow noopener" target="_blank">#CW</a>

Simon DC6STDuring the past weekend IN3IVF and I went on a 2-operator mission to <a href="https://mastodon.radio/tags/France" class="mention hashtag" rel="tag">#France</a> <a href="https://mastodon.radio/tags/Alsace" class="mention hashtag" rel="tag">#Alsace</a> to activate some more <a href="https://mastodon.radio/tags/POTA" class="mention hashtag" rel="tag">#POTA</a> parks.We activated eight different parks in three separate sessions on Saturday and Sunday and answered a total of 317 QSOs each (39 of them Park-to-Park) under challenging conditions - rain, bad propagation, and multiple idiots trying to actively interfere 😐We just barely missed the 200 SSB QSOs in one day.

KFO̸UNKI tried to activate US-2482 again close to home. I did it QRP for the first time in a while. It was nice running such a minimal kit. I got everything but the throw line in the hard case that only exactly fits my G90. I packed the G106, usb power bank, 40m EFHW, and paddles.40m was pretty rough so I switched to 20m even though that antenna gets a fairly high SWR. I was getting contacts but the bugs were really bad. At one point I saw 7 mosquitos just on one shin and left! 😅<a href="https://mastodon.hams.social/tags/pota" class="mention hashtag" rel="nofollow noopener" target="_blank">#pota</a> <a href="https://mastodon.hams.social/tags/HamRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#HamRadio</a>

The first 10 QSOs (conversations) were 2-operator on SSB with my wife doing her first-ever activation, then once she successfully activated and called it quits, I went on to hunt another 10 park-to-park QSOs on CW before we packed up. This was my first solar-powered POTA activation. ❤️The map really shows the skip today. Also, WI and MN were really booming, several folks there sounded like they were next door. CA faded in and out, tried and failed to get a confident full exchange with a few operators on the west coast. Heard a German POTA CW station quite clearly without much QSB, but they never heard me.I tried to match speed with each of the other activators I worked, and had CW QSOs from 13 to 22 WPM.Equipment:<ul><li>100W solar panel</li><li>Homebrew power distribution box incorporating solar charger</li><li>12V 10Ah LiFePO4 battery</li><li>Icom IC-7300</li><li>JPC-12 antenna base, on Chelegance lightweight tripod, no coil, partially-extended 17' whip with cap hat, tuned with nanovna</li><li>Homebrew 3d-printed <a href="https://gitlab.com/mcdanlj/Single-Paddle-Key" rel="nofollow noopener" target="_blank">single-paddle key</a></li></ul>We might need to buy a season pass to the local parks, though!
