MUF vs Critical Frequency: Unraveling Ham Radio Propagation

Welcome to our video on MUF vs Critical Frequency. In this highly informative and engaging presentation, we delve into the topic of Ham Radio Propagation and explore the relationship between MUF (Maximum Usable Frequency) and critical frequency.
🔍 What is MUF? How does it differ from critical frequency? 💡 Gain a deeper understanding of the factors influencing MUF and critical frequency, including ionospheric conditions, solar activity, and geographical location.
🌐 Don't miss out on this opportunity to unravel the mysteries of signal propagation! Sit back, relax, and let our explanations guide you through the fascinating world of MUF vs Critical Frequency.

Thanks for the great “MUF dive.”

[@TheSmokinApe]

👍

[@BusDriverRFI]

Lick the MUF by best understanding critical frequency. Make lots of contacts that way.

[@TheSmokinApe]

👀

[@kumasu]

I appreciate that this channel is educational, without requests to "mash the like button." Thank you for being a good teacher and a helpful elmer.

[@TheSmokinApe]

Thanks man, I try to put out content that helps 👍

[@Eric10179]

MUF Education is essential. Thank you for sharing this knowledge.

[@TheSmokinApe]

Exactly!

[@AndyAAzeroAM]

Good video Ape! 49 year old me got alot of good info and understanding. 18 year old me will laugh about this for days! BMUF!!!

[@TheSmokinApe]

Thanks for watching OA 👍

[@michaelko4ehb578]

Super helpful overview! I've seen the MUF map before but didn't really understand how to use it. Now I do. Well done video.

[@TheSmokinApe]

Glad it was helpful!

[@Swamp-Fox]

Thanks for the clear and concise MUF vs. Critical Frequency discussion!

[@TheSmokinApe]

Thanks for checking it out SF 👍

[@WECB640]

Excellent review Ape!

[@TheSmokinApe]

Thanks Hollywood 👍

[@Cliff-KI5OPP]

Great as always

[@TheSmokinApe]

Thanks Cliff 🍻

[@ornithopterindia]

👍Thank you sir.

[@TheSmokinApe]

Thanks for watching 👍

[@mikeZL3XD7029]

Mate, You should do audiobooks. Thanks for another great video!

[@TheSmokinApe]

LOL, thanks Mike!

[@bob_mosavo]

Thanks, Ape 👍

[@TheSmokinApe]

Thanks for watching Bob 👍

[@DonzLockz]

All this MUF n' stuff is confusing me.😖 I'm gonna have to watch it again and do some more homework so I can sit for my next test.👍🤠

[@TheSmokinApe]

lol, good luck with the test 👍

[@WECB640]

"HR MUF n' stuff, can't do a little cuz you can't do enough."

[@TheSmokinApe]

Hollywood is correct!

[@MikeN2MAK]

Great explanations and very helpful as I'm reading about propagation on Mars. Fun fact: the critical frequency on Mars is around 4Mhz, +/- a little depending on the solar cycle, so about a third of what it is here on Earth.

[@TheSmokinApe]

I’m still planning my Mars activation. Thanks for watching Mike 👍

[@temporarilyoffline]

That as they say... is that.

[@TheSmokinApe]

Exactly. That said, this is what this is…

[@markharrison1160]

The ole MUF map which I find to be helpful.

[@TheSmokinApe]

Always check that MUF map!

[@user-tl5tt5yw3c]

The atmosphere is a conductor ,a path ,

[@robertmeyer4744]

That was great. that is a great tool for chasing DX . what a storm that came threw the US. I am in NY and we got the high wind and heavy rain . crazy warm one day. up around 50F . day later 32F . power out all over. trees down all over. but intense storms has a effect on propagation . I noticed this hear threw the HF bands as it moves. a nice marker to listen to is WWV/WWVH . and they on 25 MHz now. outher types of skip is NVIS and multi hop. and of course ducting . but I find the MUF a great tool to get started. I made many 10 meter contacts when the band was down. solar min. used gray line . does not last long and changes all the time. this data on the MUF map is near real time. WWV sends the solar data as well. they send some funny sounds tracking propagation as well. when no internet that a on air way to track conditions . WWV 2.5/5/10/15/20/25 MHz . they on 24/7 . I sync my PC clock manual to that beep and got me close enough to work FT8 with out internet or GPS. my PC laptop keeps good time except when real hot of cold then it drifts. 73's

[@TheSmokinApe]

Yeah, we did have a pretty nasty past few days. Thanks for watching Robert 👍

[@goobercrow198]

Great content as always! However, next time you're on a DXpedition to Nepal operating on Mt Everest would you please let us know! I don't have Nepal in my logbook

[@TheSmokinApe]

Next time I am there I will call you 👍

[@BobN.WB1EVU]

Thanks for a great explanation of MUF. But, 2 questions...refracted vs reflected? And shouldn't the earth be flat in that first graphic?

[@TheSmokinApe]

Hey Bob. Refracted is the correct work for bouncing signal off the sky AND unfortunately I couldn't find an actual correct depiction of the flat earth. The spherist agenda runs that deep...

[@mattstosh6960]

In Alaska, MUF should be correct (as with everywhere else) but many times MUF is 7 MHz (or something) and here I am banging away on 20m and making plenty of contacts. MUF is an ok "tool" but you really don't know util you turn the HF radio on and try. Alaska does indeed have a tilted ionosphere which complicates everything, many times making it more fun...

[@TheSmokinApe]

Yeah, MUF is an estimation. You make a good point about getting on the air and trying 👍

[@jamesknotts1546]

I watch your videos all the time just realized that I never have subscribed sorry 😂

[@TheSmokinApe]

lol, no worries Jim. I appreciate you watching and the sub 🍻

[@jamesknotts1546]

@TheSmokinApe I'm subscribed for you now and I appreciate your videos and not every KZbin person comments on every comment like you do

[@TheSmokinApe]

I try to be good but do miss a few. Thanks man!

[@user-tl5tt5yw3c]

There would have to be refraction of great distance ,because of the angles ,does refraction really qualify to describe this distance or is this distance really just conductance for hf ?🤔

[@TheSmokinApe]

The angle of the refraction is the incidence angle, it’s based off the takeoff angle of the signal and the angle determines the distance. Hopefully I explained that correctly 👍

[@user-tl5tt5yw3c]

@@TheSmokinApe I think your explanation is correct in the teachings but I question the teachings ,it seems hf is similar to vhf ducting not refraction ,it is difficult to imagine refraction can be responsible for dx using hf ,and I think it's more of a conductive path the atmosphere is providing for dx not so much a refraction due to changing medium thanks for reply❤️👍

No muf too tuf
