The first launches in the American Rocketry Challenge get underway in a few minutes! Good luck to all the teams participating!

Come by the ARISS tent and find out how your educational team might be able to talk to the ISS Crew via

UPDATE! Due to rain, the event is delayed until tomorrow (SUNDAY!). See you then!

What saddens me is so many hams think a dipole is best because it presents a "perfect match" of 50ohms. Wrong. A dipole is roughly 72 ohms if you are lucky and wildly different depending on height and structures nearby.
Yagi antennas are even worse depending on the design and often need an antenna tuner hidden at the antenna. Get the lowest loss feedline you can use and don't feel guilty about the tuner in the shack.

@va3db Well, if you have 72 ohm coax and a tube radio it's perfect.. works great for me! 🤪

This can't be good, and it smells of a breach or being pwned by ransomware.


@Josefius@mastodon.radio avatar

Good news, the radio club president (KR3LL) and friend works at Kicker and took my LCD module and de-soldered it after which I was able to complete the assembly. It all fits in the case and aligns perfect. I was able to tune it fine. However I'm not getting any RF power out, I can receive fine when connected to an antenna. Do you have any recommendations for tracing the issue?

@Josefius @WS0SWV There is Iambic A and Straight

@WS0SWV@mastodon.radio avatar

@N4JAW @Josefius Pretty sure I have. I will again though.

At the AMSAT Forum at Hamvention on Saturday, I’ll be showing off this prototype 2U CubeSat Simulator.

If you are there or stop by the AMSAT Booth on Friday or Saturday, make sure you say hi! 🛰️📡😁

Any ham radio folks try aurora scatter the last few days? #aurora #hamradio https://community.spaceweatherlive.com/topic/3207-aurora-scatter/

@kr1st@mastodon.radio avatar

@ai6yr I made 59 6m AU SSB Q's. It was nice to see 6m packed with CW and SSB signals for a chance as AU renders FTx useless.


@kr1st Oooh, awesome!!

Got some clips designed and printed to mount my radio in the Honda Odyssey. It’s a good fit! Now I just need to figure out a solution for the mic.

@cassidy@blaede.family avatar

@brainofdane nice! What material did you go with? If it’s PLA, beware of extreme warping/shrinking in the regular heat of a car; I have had several prints melt in my and my in-laws' cars. 😬


Since my portable shortwave receiver is hardly picking up anything on HF (including no WWV signals), I think I'm going to wait a bit before digging out my antenna and related gear for working this month's weekend sprint.


@sclower I'm in the middle of a huge move, so have nothing to do anything with. However, I would have thought all the heavy geomagnetic activity this weekend would be improving HF propagation.

@kwf@social.afront.org avatar

These solar storm numbers make me wonder for a moment how much fun I'd be having this weekend if I had picked a normal hobby like instead of building Internet infrastructure in my free time.

@k8vsy@mastodon.radio avatar

@kwf the bands are completely dead here in Ohio, US 😂😂

I wish they were doing something cool, but it's completely silent lol

@kwf@social.afront.org avatar

@k8vsy even on 6m?

There's a thing that really bothers me in the #HamRadio world. There's a bunch of videos and articles about how to use HTs. How to program them for repeaters, Vox, etc.

I've been a ham for about a year and a half. I have never struggled with how an HT works. Where is the demand for all of these resources?

Once you understand the concepts at play (which, sure, are novel to a new operator, but aren't particularly complex), it's a simple matter to look up how to set a tone on an arbitrary radio.



There's a thing that really bothers me

This I cannot relate. Why would something bother me that

a) others are doing for free and

b) for fun and

c) that I can easily ignore?

Live and let life!


Hmm, Gigaparts selling a $900 "mystery box" all-band (UHF/VHF/50/HF) radio. 🤔

@bud_t@m.ai6yr.org avatar

@ai6yr I saw that. Pretty sure it is an IC-7100 from the description.

@va3db@mastodon.radio avatar

@ai6yr hmmm sounds like the TS2000

Subject: check-in

Message body line1: [callsign], [firstname], [city], [state/province/locale], [country], [mastodon username], [VHF/HF/APRS/Telnet, etc]

Message body line2: Do you build your own antennas? [Y/N feel free to explain]

Message body line3: Do you agree to have your callsign shared in the check-in list? [Y or N/opt-out]

Please boost and encourage each other to practice using Winlink!



@bud_t Hmm... looks like Telnet or figuring out our VHF system here, LOL... bands are wiped out!
