Amateur Radio Repeaters can be complicated beasts, but we’re here to demystify them! How do those ham repeaters work? What about all the equipment and how it all fits together?
We’ll discuss:
– How a repeater works, Inputs/Outputs, CTCSS, roger beeps, tails, transmitters, receivers
– Controllers, Duplexers, Coaxes, Antennas, power supplies (solar and what to think of)
– Linking (RF & VOIP)
– Duplex noise & how to cure it
– Effective sensitivity testing, intermod, isolators
– Simulcasting and Voting
+ MORE if we have time!
Repeater Basics Ham Radio Part 1
And, here is a quick “How to” on basic repeater operation that a Ham radio operator will find commonly in 2 meter and 440 operations.
Just got into the hobby and have been trying to understand the theory behind these repeaters. This was straight to the point thank you. No excessive junk i dony need to know.
i am into one of my repeaters but i can here them but when i press ptt i do not get any response back from repeater dont know what to do despite watching 5 vidoes on this my model is pofung 82r
Now this video was helpful!! Thanks a Million!!
I think radio-line-of-sight is best thought of as optical-line-of-sight but if you had superpower eyesight capable of seeing 10 miles, 50 miles or even more sometimes into the distance.
You are almost like having an Elmer, 73.
You are the first video of many that I have watched that actually explained how this works in a way that a beginner like me can understand. So many others instruct as if I should already know what they're talking about instead of teaching me the basics. Thank you!
What does the (+) and (-) mean nest to the repeater frequency?
So I want to talk to my brother who is 50 miles away, who just got his General. I have my General too. I cannot reach him directly, nor can he reach me directly, as we only have 5 watt Baofengs. How do I find the repeater(s) and the frequencies they work on which are between us so that we can link up ?
can 2 repeater work on same frequencies for example rx 145.00 tx 155.00 placed 20 miles apart to increase range?
I took two handhelds programmed the exact same they can hear the repeater I’ve gotten verification but i can’t be heard on the other handheld..? And ideas?
great info. thanks.
Love this explanation of repeaters. Thank you!!
International Space Station now has a repeater on board.
is this still good today?
Great stuff as always, guys!
Cheers!
Nicely done. Relatively hew ham here enjoying your channel.
Great video guys. Wish this was around when I first started.
TeamReplay for the win! I would be interested in a better understanding of the LMR coax issues.
Hello this is WP4KY . can you make a video expling what is a voting receiver on a Ham Repeater ?
Can i usted 4 comet GP-9 Antenna on stacking for the receiver and 4 comet GP-9 on stacking for transmit
the NYC repeater you are talking about is 147.000 WB2ZSE not only dose the door bell but a whole host of other tones
