- I made this ideo for Video for Dirtbike 5100 check out his channel this dummy load has an average of 2:1 to 1 SWR which isn't bad for working on a Radio Experimenting with differ bulbs helps It is more of a Novelty Item Please use on a cheap radio while testing / dirtbike5100
Novelty and cheap radio are the key words.
Would work ok on a CB for short distance comms as you've mentioned.
Now if any one is wanting to build a good, workable dummy load, don't use light bulbs. The element in the bulb is a wire wound filament and not give you a true VSWR reading.
Good enjoyable vid never the less sir.
Novelty item is correct. Using a cheap radio you dont care about is also correct. With a few modifications you can make this a true 50 ohm dummy load and hook expensive radios up to them for bench testing , alignment, and mods.
yougotsbusted PUNK I have made one with a good s.w.r. and talked over 2 miles on it You can really mess with peoples minds when only the person close to you can hear you
not2fast4u2c What are the ohms of your build before hooking anything to it?
I'm gonna have every maul-dropper in the country subbing to me, thanks for the on the air plug!! That's a pretty cool toy, I'm going to have to make one of them.
That's pretty cool, never seen that before...Cheerz!!
Thanks !!!
Use a fine tooth comb to unbraid it. Fast and works good.
BirdWhisperer46 Thanks !!! I never thought of that
Nunca utilize uma lampada como carga não irradiante em equipamentos com transistores de potencia ou FETs na etapa final. Há mais de 40 anos atrás, quando tínhamos equipamentos com etapa valvulada e tanque de sintonia em PI até suportariam o descasamento, coisa que não ocorrem com os atuais - é um risco desnecessário de causar danos ao equipamento.

Would this work on a 10 meter QRP rig?
What terminal does the braided wire go to ?
OUTSIDE GROUND
eles e que sao dummys e nao o load, eles nao sabem o que estao fazendo, eles nao sabem como fonciona uma lampada com filamento tungsten quando esta fria e depois quando atinge 2000 graus centigrados no filamento ,rt= (1+ cof x r inecial( temp inecial-temp finlal)
Hellova idea ... curious would a LED bulb work also ?
No
You Do Not Want to hear me sing Trust Me !!!!
Ah come on and sing. I promise I'll turn my volume off!!! lol
