Wow, I'm surprised by the price. I thought for sure it would be at least twice of what they're charging. I think I may need one of those. 😄

It's still open here at 6:45pm local. Lot's of signals on FT8 and a few on SSB.

010

Alex KR1ST/PA1ST @kr1st.bsky.social · 06/01/2026

I just made a good bunch of SSB QSOs on 6m. You may have to tune around a bit between 50.125 and 50.200 MHz. Since the 818 doesn't have a band scope you may miss a string signal higher up the band while the calling frequency may be dead. When 6m is open a vertical should work just fine.

Alex KR1ST/PA1ST @kr1st.bsky.social · 06/01/2026

I didn't expect to see an opening like this over here either at this time of the year. I'll see if I can push the Es cloud a bit in your direction. 😄

Just in case you weren't aware yet, 6m is open in North America. #Hamradio #AmateurRadio #hamr #6m #FT8

It doesn't look like it, but I worked my best DX on 70cm today. My signal traveled 448,000 miles, or 717.000km, to cover a distance of just 149 miles (238km) for my first EME QSO. 😀

I'm surprised they still use that range of frequencies. I don't know what would be a good FM receiver for that range. I just got a DJ-X100T a few weeks ago that seems to work very well (got it for RX of DMR/DSTAR/C4FM) and has decent audio but I'm not sure how well it receives the VHF low bands.

Yeah, we saw that too! My wife and I play Connections and Spelling Bee pretty much every day. Hamradio has also appeared in the Spelling Bee game before I think.

Looks like it keeps transmitting the same image on every pass.

I don't know at what times you are trying to work MS, but late evenings and early mornings are the best times here. During the day the Geminids are below the horizon so I'd hear very little MS.

SONATE-2 SSTV (Martin 1) images as received on 145.880 MHz at the 20:09UTC pass this afternoon. I was too late to correct the slant on the first image, but was able to do so on the second image. Something hosed up the transmission of the 2nd image. No interference. #hamradio #AmateurRadio

Very nice!! I will see what I can receive on the 20:09 UTC/ 3:09pm EST US East Coast pass this afternoon. Hopefully I set it all up OK.

To find out where to look in the sky for meteors, or where to aim your beam for #MeteorScatter, try the old Virgo app (Windows and Linux) maintained by DB1BM and DL8AAU: www.dl1dbc.net/Meteorscatte... You do have to enter your grid every time you start it, unfortunately. #hamradio #AmateurRadio

Screenshot of the Virgo app. It shows where the meteor storms are originating from in the sky. At this time it shows the Geminids setting in the NW. The compass dial is showing lines indicating where to aim the antenna, SW or NE in this case for the Geminids.

LOL! I bet you do get a lot of requests like that. 😄 These F2 openings, like we also had to the west coast and Europe last week, are so nice because we don't have to compete with stations that are a hop closer during a multi-hop Es opening. Signals are a lot stronger too.

010

Alex KR1ST/PA1ST @kr1st.bsky.social · 03/12/2024

Ah, that was you on the other side! Awesome! It was so good to finally see Alaska on 6m. So often I've seen propagation stretching into your direction only to abruptly drop after working a few stations in BC. This time it just opened to AK out of the blue. Funny band 6m. 😄

Alex KR1ST/PA1ST @kr1st.bsky.social · 02/12/2024

I didn't organize this or had anything to do with the educational aspect of it. I just happened to learn this morning that this school contact was going to happen and decided to record it since I had the day off anyway. 😄

It's really cool to see how they built the rhombic antennas back then and also the hardline made from tubes.

Alex KR1ST/PA1ST @kr1st.bsky.social · 25/11/2024

If you notice that it seems like the pi-star dashboard stops displaying Gateway Activity and Local RF Activity but is otherwise working just fine, check the disk usage of /var/log. If it's at 100% check the FileLevel logging for the gateways and make sure it's set to 0 and reboot. #hamradio #hamr

Screenshot showing the results of "df -h". It's showing that only 1% is used by /var/log now, but this was at 100% when I discovered the problem.

Screenshot of the Configuration>Expert>DMR GW page of the pi-star dashboard showing the FileLevel set to zero in the "Log" section.

This was set to "1" which means that every byte going across the gateway gets logged filling up valuable disk space.

I probably fat-fingered this myself. :)

Of course, this may also happen for gateways other than the DMR gateway.

Alex KR1ST/PA1ST @kr1st.bsky.social · 22/11/2024

It's snowing alright! youtube.com/shorts/1-ckq... That explains why the SWR on my antennas are slightly less than ideal tonight. 😄 #hamradio #AmateurRadio

I hear ya! I also have only 3 elements on 6m. I was going to put 5 elements up this summer, but life got in the way. Maybe next year. I too prefer 2m and 70cm over 6m, but there's just not that much activity on those bands, so I often hang out on 6m while checking for activity on the other bands.

010

Alex KR1ST/PA1ST @kr1st.bsky.social · 21/11/2024

I see we worked each other on 70cm and 2m, but never on 6m for some odd reason. 😄

Ah cool! You can search for hamradio feeds that someone has already built by clicking on the # symbol in the app or website. Just now I added the Amateur/ Ham Radio feed by AD6G and that seems to contain only hamradio stuff. Of course I now want to know how to create my own feed. 😄

Alex KR1ST/PA1ST @kr1st.bsky.social · 21/11/2024

I was wondering if you can filter posts by keywords on here, but I'm not seeing it. It would be nice if you could set things up so you only see posts with specific #-tags. Maybe you can do these things, but I'm too much of a BS noob to know. 😄

Alex KR1ST/PA1ST @kr1st.bsky.social · 20/11/2024

I don't collect wallpaper but do upload my log to QRZ and LOTW for those that do. However, I do send QSL cards at times still, especially if I know the other station is a new ham, or someone returning to the hobby. It's just to send a friendly "hello" and that I appreciate them joining us (again).
