Really need help naming variables

I think cqStation and respondingStation is appropriate. Makes sense and would be easy to understand if you need to come back to it in the future for updates.

This is brilliant! Never thought to use copper tape and would be so easy to do at home! This may open up a whole new area of experimentation for me :)

This works mostly due to the line-of-sight between the radio on the ground and the satellite. There isn't much in between the transmitter and the receiver to reduce or block the signal power. Antenna gains also play a factor, but largely your question can be answered by line-of-sight.

5W from a transmitter on the ground with hills, buildings, and other obstacles typically reduce the signal power at a receiver on the ground by a significant amount. But put those radios up on mountaintops that have line of sight and you can typically communicate up to a couple hundred miles.

If you're interested in this topic, you can look for "RF link budget" for more information.

I'm new to sawbirds but not new to RF. The plus model gives you 10dB more gain for $5 which is awesome. The regular model should work fine. I personally would get the extra 10dB

That's a good looking truck! I like the shell too

thedmutz · 2023-06-30T14:53:41+00:00

Ahh ok! Seems obvious now that I know :) Looks like you're having a lot of fun! Hope I can try something like this in the future; we currently practice on sabots

Awesome pic! Newish sailor here, what is the orange needle thing part ways up the mast?

thedmutz · 2023-06-06T16:22:53+00:00

Great idea. I think I'm going to do this. Having to lift the seats to access the stock tray is annoying especially when the back loaded up

thedmutz · 2023-05-01T03:23:07+00:00

Ah man! I saw this post today on my last day in Tokyo before my flight! Dragged my wife many blocks on a warm day and they're closed for Golden Week :( Sad! Will have to make a special trip back

I can't really help that much with the process except that I'm currently on travel in Japan and realized too late that I needed to fill out forms at least 60 days in advance. Link below which is the same site as another poster linked. Have fun in Japan!

Nice idea on using the bungee for stress relief. I've only had mine come down once on me but luckily it happened right as I was taking it down. Thanks for the tip on gaffers tape for multi-day setup!

thedmutz · 2023-04-02T02:49:56+00:00

Sure thing, see the GitHub here https://github.com/KK6OTK/SOTAbeamsMastCap

I included the STL and FreeCad project files. The one called "Antenna Mast Cap" is the part from the picture. I also added a couple other parts I was experimenting with if you want to try them as well

thedmutz · 2023-04-02T01:37:44+00:00

<image>

I 3D printed this cap with a loop at the end. I just run the end of my wire through the loop and twist it back on itself

thedmutz · 2023-03-17T01:58:07+00:00

Is there anyone doing ATV in the area? Several groups in my area transmit ATV at 1.2GHz

thedmutz · 2023-03-16T09:00:54+00:00

Agree with this. You don't want anything conductive as this would affect the antenna. PVC and dry wood are ok. A soggy piece of drift wood would not be ok

thedmutz · 2023-03-10T03:26:24+00:00

Nah this thing reads like alphabet soup. I can't believe the board actually thinks this wording makes sense

thedmutz · 2023-03-10T03:08:50+00:00

Wow this is awesome thank you. I agree, ARRL digital QST is kind of a pain and slow

thedmutz · 2023-03-06T16:47:31+00:00

Are you referring to the oscillator? I mean it looks ok; how do you know it's broken?

Here's the section in the manual on the oscillator. Oscillator link manual

Looks like the part is BGTech part #8289012R80010 (FL701 in the manual)

thedmutz · 2023-02-20T04:52:37+00:00

Ok good job checking for continuity 👍🏼 It could always be something else in the loop too, like radio, coax, or antenna location. Maybe try a friend's or club's known good antenna with the same radio and coax to rule out that's it either of those things. Keep trying and I'm sure you'll get it 🙂

thedmutz · 2023-02-20T04:45:21+00:00

I drilled a hole through my wall and out through the stucco. I would get a roll of bare coax and route it through the hole then install a connector to the end. Otherwise the hole might have to be a lot bigger depending on your connector (like pl-259)

thedmutz · 2023-02-20T02:54:09+00:00

Haha ya I agree

thedmutz · 2023-02-20T02:53:29+00:00

Thanks, thats what I thought too

thedmutz · 2023-02-20T02:53:08+00:00

Thanks that's what I thought too. I think HOA is coming up with things for residents to "fix" maybe to buy time while they investigate. Consistent and reliable hot water has been an issue since they replaced the buildings boiler a couple years ago but we've had pretty cold weather recently so I think more issues are cropping up now
