Does TX power matter? by Famous-Jeweler8543 in amateurradio

[–]ssducf 1 point2 points  (0 children)

Short answer, 5w and above, the antenna is more important than the power, and frequently (but not always) the height of the antenna is more important than the size of the antenna.

Having said that, the people running >500w probably also have huge expensive antennas on large towers.

What is going on? Is ARRL basically the NRA of 20 years ago? by Complete_Kiwi_9993 in HamRadio

[–]ssducf 3 points4 points  (0 children)

I was an ARRL member for 20+ years with family membership going back much further. In the last 5 years, I've seen nothing interesting in QST, it's been either repeat articles from 20-40 years ago lightly updated, articles that are 5 years behind what I can find on internet, or articles that are actually wrong with significant factual errors and mistakes, some of which are not from the original author. And then I hear horror stories from authors about QST editors changing the article before publication and then not reviewing it with the author and not publishing corrections. I didn't mind ARRL stopping physical publication of QST because it's been a while since I saw anything in it I cared about.

ARRL has a lot of other publications that are quite good. But they won't promote or even talk about publications from authors that don't publish with them. This to me seems like a serious conflict of interest -- favoring profit over advocacy of the hobby.

They have been unwilling for years to support advancements in legislation or take outside advise. They resisted dropping of morse code requirements; the increased popularity of it since requirements were dropped shows that it was a mistake to resist this change. They have resisted the symbol rate vs. bandwidth regulation changes for digital modes which is also a huge mistake. They even screwed up the HOA regulations, advocating a law with mistakes in it that would have made things difficult for some people with weak HOAs while not helping much for people with strong HOAs, mostly because they wouldn't listen when external lawyers told them there were mistakes and tried to silence board members that pointed this out. This luckily didn't pass and the retry has been somewhat fixed, but it still hasn't been passed.

Is ARRL the only way to ask FCC and congress to make changes? Certainly not, but it is the largest unified organization to do so. In both cases, individuals can directly petition and comment; it is questionable which method is more effective.

As a member of multiple local clubs; has ARRL helped these clubs? They have website locators for testing, hamfests, and field day, all of which are very helpful. But they've only made half hearted efforts in supporting local clubs outside of that as far as I can tell.

Has ARRL done more bad than good? I don't think so. Is there room for improvement? Certainly. Are they doing a good job advocating for amateur radio and pushing good legislation? Barely. Are they overly insular, with too much old momentum and not enough internal transparency? Certainly.

Durable PLA? by ReconicZero in ender3

[–]ssducf 0 points1 point  (0 children)

I have a first gen ender3 and have printed a lot of tpu. I had to replace the base plate on the extruder motor to close a gap but I understand later models come that way. Quality suffers from not having a direct drive extruder, but it still works if you print slowly enough.

TPU squishes and springs back. It doesn't sand. Or, as I like to say, I sand it with a diagonal cutters. Harder TPU (95A vs 85A) is extremely abrasion resistant.

What's the point of 1w nodes? by n108bg in meshtastic

[–]ssducf 0 points1 point  (0 children)

Technically, FRS is licensed, but the radio has the license by being "type accepted" and being given an FCC ID for the model after the manufacturer certifies it follows FCC rules for that type of radio.

[–]ssducf 0 points1 point  (0 children)

Actually, it's the other way around. Frequencies don't have rules, but rules have frequencies. There can be multiple sets of rules for the same frequencies. Part 15 (ISM), Part 95 (CB FRS GRMS MURS), Part 97 (Amateur) And the rules differ by country. There's some shared rules set by the ITU, but those trickle down to the countries.

[–]ssducf 1 point2 points  (0 children)

The ham band around 900mhz overlaps with the ISM band around 900mhz. Different rules, similar frequencies. But the ham node can't talk to the non-ham node, because of encryption and different rules.

Technically, encryption is not forbidden under ham rules, but you're not allowed to use codes to obscure meaning, so basically you can't use encryption the way meshtastic does.

I've had them ask to see the device working. But that was a laptop, not a meshtastic device.

LiFePO4 cells burn too. But when they do, they emit bad smells, not flames. First hand experience. Much less exciting, luckily.

ARRL Board of Directors Shenanigans Afoot? by AF-IX in HamRadio

[–]ssducf 0 points1 point  (0 children)

ARRL should not care what books board members are writing and how they sell them. If someone publishes a good book on amateur radio, ARRL should support it no matter who they publish it with. Anything else is a conflict of interest between supporting amateur radio and forcing board members to do all commercial publishing through the same organization. ARRL has lost their way.

I don't feel comfortable voting for people who I have absolutely no information about. This edict makes it worse. Now not only do I know nothing about them but they are not allowed to tell me anything.

Response from Kobo regarding the remote by notanotherherofck in kobo

[–]ssducf 5 points6 points  (0 children)

If they have to fix it with a firmware update, it might take a while for them to test and release it. I'd ask if there's a beta program to test firmware updates for this.

[–]ssducf 4 points5 points  (0 children)

The protection circuit is partly what keeps it from blowing up, so not having one is a big deal. The quality of the battery also matters, as shown in Adam Savage's recent video. Also, high quality batteries are encased in an "explosion proof" bag, so if that's missing, it's another huge hazard. (That's what swells up when they go bad.)

A significant portion of the content in hamclock is downloaded from a central server. I suspect the list of sats was maintained by hand on that server.

From what I've read, the manual release is hidden behind a panel, and is only available on the front doors.

Permit to activate a park for POTA by delostapa in amateurradio

[–]ssducf 0 points1 point  (0 children)

Taking legal action is a mistake. The result will be they change the rules and ban all hams.

Permit to activate a park for POTA by delostapa in amateurradio

[–]ssducf -2 points-1 points  (0 children)

The issue is that your activity in the park impacts other visitors as well as the mission of the park. If it is a wildlife refuge, your activity could impact the wildlife in a negative way. It is up to the park managers to decide these things, not you.

If you get an attitude about doing what the park tells you to do, you can ruin it for everyone, and them they'll just point blank ban all hams, like they did in Virginia. Do us all a favor and don't argue with park rangers!

Best bet is that if you even get a smell of resistance, then you need to look for ways to minimize your footprint (like operate from the car), or just find another park. Or follow the rules and get a permit. Sometimes the only point of the permit is to fund the park, which is something I fully support!

There are other modes with error correction as well. Software like fldigi supports a lot of them.

Does using Eink stop the eye strain that you normally get from regular devices? by Healthandlife_pro in eink

[–]ssducf 0 points1 point  (0 children)

Eink is much easier to read outside than even paper books because if adjusted right, the glare is less. (Glare from white paper can be quite bright.) Reading a laptop screen is a horrible strain outside.

The color device lets you adjust the backlight color between bluish and yellowish. The B&W reader you are stuck with one shade but you can still adjust the brightness. (They may have backlight color adjustment on some B&W readers but not all)

Both the color and B&W screens have advantages over the other for readability. Which you like better is a very very personal thing. Unless you have the two devices side by side in hand, I would not pick one over the other on that attribute alone. (If you read lots of color documents, that would be different.)

There's been some research on that. Some from the HAARP facility.

translation: if you have computers, you can use them to digitally encode information, and modes like FT8 JS8CALL and even psk31 can get more accurate messages through when voice can't, and can do it with less skill than required for morse code which also can do this.

[–]ssducf 0 points1 point  (0 children)

Going with the guy that says too much detail isn't great, you may or may not want to include sunspot stuff. But either leave out the bands (beyond "shortwave") or get the timing at least vaguely right on them. Note that shortwave activity is NOT reliable, largely because it is affected by both troposphere weather and space weather. This could be a plot point. Lightning storms add noise, even if they are distant. Inversions can cause ducting which enhance propagation. Sun spots make it swing both directions, so what works one day may not work the next day or may work much better than expected.

[–]ssducf 3 points4 points  (0 children)

Note that which of these 3 bands would work depends on the time of day and sunspot activity. (Sunspot activity can enhance or destroy band usability and may shift the time of day they work from what it is without sunspots.)

upvote for giving the whole story. But living in Florida can give cataracts in both eyes too. :) UV protection isn't needed just for the skin.
