Inexpensive Emergency Repeater Option For Ham And GMRS, Red's Engineering SRPT 02!

[@chrisdelong2932]

Just a word of warning: someone in my neighborhood has a Hack RF type device. It captures your transmit signal with PL/DCS code and then they are able to simply push a button and retransmit your identical signal into the repeater. They are able to store the parameters of your transmission and thereby access your repeater again and again. Someone nearby enough to capture my HT signal was messing with my simplex repeater here where I live. Just so you know. People are and will be malicious, simply out of boredom, or simply to be malicious. Thanks for the video think I will order one of these I have several of another brand attached to 40 watt UHF & 50 watt VHF mobile radios. Seems to work well. Same thing 30 feet of antenna height. Thank you. 73’.

When radio shack was imploding, I got a discone antenna from them for a big discount. I really don't know much about HAM. What is a discone antenna good for?

[@Iridium242]

If its the one i remember, it was a scanner antenna

[@MI_Prepper]

@Iridium242 So, is it not good for HAM?

[@dherbert8288]

Receiving. Not good for transmitting.

[@Iridium242]

@@MI_Prepper You can listen but I would not try to transmit with it. Its not going to be resonant on ham bands

[@jarredjones8476]

Some discones are wideband And CAN be used to teansmit

[@BigVegasVinny]

Hello love your videos I live in Vegas. May I ask your opinion about that simplex peter and the many Chinese simplex peters on eBay and or the duplex versions. I’m just wondering if it does anything different than the standard ones that are already available

[@HEYDUDEPUTINWANTSHISMONEYBACK]

Do you need an amp? Looking for emergency communication within a 15 mile wide area roughly.??

[@chrissewell1608]

There are problems with simplex repeaters, with HT's. 1) Battery power. (You seem to have accounted for that one, w/ a 12VDC LifePo battery. 👍) A person can calculate power consumption of all electronics, vs. Battery life, and then factor in average in your TX consumption... 🥺 2) Small Antenna and power. This is easy enough to overcome w/ an external antenna! (And you have a small amp! 👍) Every Ham Operator knows how to manipulate those features for maximum effieciency! 3) Duty cycle and heat build up. This is the killer, and why commercial repeaters are built so heavy duty! Most people don't realize, their radio(s) are constantly ON and active. This can build up enough internal heat to fry the electronics on small radios &/ batteries! And to much use, can drain the battery. 4) Waterproof container. You want something small enough to carry &/or hang up high, and possibly conceal from thieves / vandals. Yet large enough for all you stuff, with room for air flow, and some sort of ventilation! ... 🥴 Mind blowing 🤯 all the sudden crap, that can go into a Simple, fun project! My suggestion is the KISS method. Then go from there, if needed! I am looking forward to what you come up with!

[@BrightEyeSecurity]

I have one! Works as advertised. It's a good idea to have one for property security. You have one of these with a larger attenna and a 10 watt radio in the center of your property and it helps those in your group with "lesser" comms.

[@kenanderson7321]

Does it only record 10 seconds of voice per transmission or is that adjustable and if so what is the max?

[@timbookedtwo2375]

An HT with crossband capability is an alternative. I have a wouxun HT that is crossband capable. put it in a waterproof box with a battery, solar charge controller and outside a small solar panel and you'r good to go.

Little hint-if using ctcss or dcs and want single frequency simplex only,but want semi duplex without tx shifting offset,use split ctcss or dcs lot of the new CB and LMR radios fm+ctcss support split ctcss or dcs sub tones ch base 1 tone 1 tx ch base 1 tone 2 rx ch mobile\HT 1 tone 2 tx ch mobile\HT 1 tone 1 rx now you have semi duplex split shift sub tones on a simplex frequency! stops ring around too on close by hts or mobiles,than just using single tx x sub tones. looks great product 👍

[@bryansmith1407]

I have one of these as well I have the white one. I put my in a pelican case . Works great with the GMRS radios there no repeaters for GMRS in my area .

[@NukaVaultReadiness]

This is definitely a must! An elmer of mine first told me about these, and I can see how these would definitely help immediate area comms, especially in areas with heavy woods. Thank you for the video!

[@corrigan88101]

The only issue is that the voice recorder only holds 10 seconds.

[@Bootyhunter1971]

I see that as an asset on a simplex repeater. Last thing you want is some longwinded blow hard on that type of repeater.

[@HarshmanHills]

independent comms are vital these days

[@waynedoomad2573]

Great repeater do it need the amps

[@KevinSmith-yh6tl]

Looks like a solid product. 👍

[@chrissewell1608]

While Simplex repeaters are nothing new, this one is small, compact, simple and affordable. (I have an accessory chip, I installed into an older Yaesu mobile unit, that allows that radio into an simplex repeater mode. Its just a pain to use!)

[@kishantextiles6678]

I am watching this video from Bangladesh. Great work

[@slidewaze]

That's pretty cool. I can think of a few, no, actually many uses for that. :^)

[@ptsdpenguin3764]

Very informative. I could use that for my radio. Thank you for the information.😊😊😊😊

[@AR-ue9bu]

Good info. Thanks for sharing

[@weropunk61]

Can you do more than 10 seconds of record ? With some formware or someting?

[@kchedville]

I have one of these on Order -- am just getting interested in GMRS Radio and hope you make some more Video's on this Device. Thanks

[@AmberWhiskeyRGS]

Nice video, can't wait for the build. New Sub.

[@ricochetronm5385]

I'll go with you up the mountian to test?

[@Iridium242]

Ok cool

[@chrissewell1608]

Is that a question or a statement?

[@ricochetronm5385]

[@jimmyslim1628]

What is the concept of a repeater, how does one work, what does it do? I don't even know what a Hotspot is. I know Nothing about communication tech.

[@foxthree7]

Hey iridium, I just spoke with Mr Red. He is not sure if the repeater will work with a GMRS midland radio. I refuse to use a baofeng. Is there anyway you can test any midland gmrs you may have on hand with Reds repeater? My model is Midland GXT1000VP4. Thanks

[@chado_outdoors]

So say I have the repeater setup on a mountain top at my house; 25w amp, tri-band antenna 40ft high, then radio in my truck also with 25w amp...technically what kind of range am I looking at truck to repeater and range from repeater to air?

[@chrissewell1608]

Are you a Ham radio operator? Because if so, you should know this.

[@chado_outdoors]

​@@chrissewell1608 Not yet, I have enrolled in a local night school class for it. I can't read the books myself because I'm dyslexic, so I have to go to class for it.

[@chado_outdoors]

​@@chrissewell1608and so you know, an answer would have taken exactly as much effort as asking me that question.

[@fernandocharlesii8678]

I am new to ham, your amp do you have a link for that or one like it?
