Hi, no difference. I don't remember what he did, it was a while ago..

It seems fine, but I am in a fairly RF quiet location..

Thanks, none of mines ever were..

The HD1 however is part 90.

Spurious emissions are a serious concern for any responsible operator.

read the manual - yes the earpiece has a PTT on the side

They will be protected in a Faraday cage, but don't forget to also include a phone or tablet for interface.

Aucune idée..

@@RadioPrepper ... ok merci pour la réponse ... à creuser je pense 🤔

Pas à ma connaissance..

@@RadioPrepper j’ai trouvé:Quansheng uv 5 et 6 k,debridables à l’allumage dans un menu caché.

Le problème sont la très faible puissance de sortie et les harmoniques, utilisable seulement en réception.

@@RadioPrepper OK merci bcp

Revision, I now see it depends on the frequency. I was using two vhf radios in my prior tests that I mentioned and now I tried UHF and its 800% higher. I'm thinking HF should be pretty close but I will try that another time. Thanks again for the project!

It's probably a wound resistor, which makes a coil in AC. You must use a carbon resistor, or other, but not wound..

@@RadioPrepper It looks exactly like yours just 100w instead of 250w but I did get them cheap on the internet.

Weird, I only used mine on HF though, so who knows...

Might be worth a try, but finding the right value might be hard without regular taps to measure..

Sure, but not everyone has the radio or/and antenna for them.

@@RadioPrepper Not to be argumentative, but ....where there's a Will, there's a way ! I think if these folks really wanted to operate, they would find a way ! There are just too many affordable alternatives, to keep you off the air, these days ! Perhaps what's lacking is a little ingenuity ? And too, these may be Hams that haven't bothered to learn Morse Code ? Which serves well, when looking for a place to operate ! But so many offer excuses why they can't learn the Morse Code ! But I think they are cheating themselves, and missing out on great fun ! But that is just my opinion, and I don't want to stray too far from the topic ! Just offering a great escape, for those that feel trapped and helpless by Contesters !

@sleeve8651 sure, there are ways, but I shouldn't have to go out of my way to accommodate people who have no respect for others and take it all.

@@RadioPrepper Not to drag this on, but not knowing how long you've been licensed, ( Guessing you are a licensed Amateur ?), but Amateur Radio has undergone several changes thru the years ! Some through attrition, some thru advancements in technology ! Not to preach to the choir ! But the latter has likely been most influential, just by the nature of the beast ! Pushing the Radio Amateur out of their role of providing Emergency communications ! In many cases, by individuals that were in charge of Cities Emergency centers, that lacked understanding of the value of the Amateur Radio Service ! Where they chose in many cases, to throw money at it, and bought expensive, many times, " Motorola " radios, and then passed them out like candy, to untrained personnel ! And with the push from Radio manufacturers, to try and help themselves stay alive, to them lower the requirements for becoming a licensed operator ! So what we see today, is simply where Amateur Radio has morphed, into a completely different Animal ! Going from a , " Service ", to now what most think of as a, " Hobby " ! It is what it is ! The Genie's out of the bottle, and it's not going back in ! My advice, if I may, would be instead of sitting on the sidelines, would be to become involved ! Perhaps push yourself into learning new things ! Enjoy the Freedom to communicate, while we still have the ability ! In closing, as the old adage states, " If you're not part of the solution, you're part of the problem " ! 🤔.....? Just Say'n !

Généralement pas important si l'antenne est résonante, ce qui est le cas ici.

I've been called a few things, but that's a first. What could I have possibly said that might make you think that?

Of course!

Pas beaucoup, ça change juste un peu la bande passante et l'impédance. J'utilise du fil très fin..

Yes, nobody should use their callsign on 915, the same way you would not use your HAM callsign on CB.

@@RadioPrepper thank you Gil!

1to1 to a single phone.

@@RadioPrepper I’m following. Each meshtastic device can only be paired with one phone/tablet/computer. I’m not clear on the opposite. Can you have multiple meshtastic devices paired to a single phone/tablet/computer? Thanks for your educating video and taking the time to answer questions.

Not sure but the problem is that everyone is on LongFast but for a private channel, you could try slower, but not the minimum, which doesn't really work.

No idea...

@@RadioPrepper thanks

Je ne connais pas le RA79..

It looks like it would but see the manufacturer's info. I don't own a 100W radio, 20W max...

I don't remember, LOL, volume?
