- Today it's another CB radio installment and we have the Midland 75-822 Portable CB radios on hand.
These are excellent radios for general all round use including portable base and mobile. These radios come with an adapter which makes it easy to use base or mobile in your car or truck.
Today we will test the range of two units in a portable setting emulating a camp site. These radios are excellent also for your STHF applications.
We also want to thank 935 out of NY for assisting us with all aspects of this video. Comment below on this test and anyways to improve range.

Thanks for the interesting test!
Thank you, glad you enjoyed the video.
Great video to sit down and really see how far they go
Thanks for the feedback. Good to show these radios working in real world environments.
cool lil test. I did some testing with my Midland, apparently these only put out maximum of like 2 watts with a battery. Hooked up to the mobile, they can put their maximum four watts out.
Thanks, we had fun that day. For two watts not bad. These are versatile units with the car kit. Thanks for the comment.
Skip is an amazing phenomena. It brings in far signals but also kills local signals.
Shows the versatility of the CB band over others like GMRS but you must respect the skip or the skip will take you out. Similar to rip currents. Thanks for the comment. 640 out .
Great test. But I think you should do it again maybe late in the afternoon or early morning when the DX is not in there as bad then you should get more accuracy with the range
Appreciate the feedback but believe it or not but this was filmed in the late afternoon unfortunately that's when the skip tends to rolls in but that day it was what was available for us to film. Maybe next time I try around noon and see how that goes. Thanks for watching and commenting.
Interesting test in the urban environment.
I wonder how it would do out in the clear on a hill or top of a building?
Thanks for the feedback and yes it would increase the range on both accounts and plans are already on the way for another range test in different surroundings to showcase 27mhz as a reliable form of local comms to compete with frs, gmrs and pmr bands. Thanks for watching.
I've got exactly same radio and haven't really checked it's range to another identical Midland 40 channel portable, although i did a radio check on either, channel 19/ 14/ and 28 at about 6 miles from a truck stop and i received a truckers signal loud and clear, mine transmission was good he told me and not excellent, but he did hear me. So, o purchased a road pro car antenna and haven't tested yet. I got to soon.
All part of the fun experimenting with range and audio and be prepared if need be.
@@640amthemix thanks,😐👍10-4
What aftermarket antenna are you running on the stationary handheld?
HYS 27mhz telescopic whip antenna .
Good video. I’d try it again in the evening, when skip isn’t rolling.
True. A night range test. Great 💡 idea!
I get about .5 - 1 mile range with the rubber ducky antenna. I can get up to 5 miles with a small mag base roof antenna
Good range you got on these. Shame the skip took us out. We are going to put another Range test after another subscriber suggested we do it in the evening after the skip has faded. Thanks for watching. 640 out
Is skip the same as tropospheric ducting?
No according to the research desk here at 640 AM The Mix, tropospheric skip is more weather and regular skip is the atmosphere . Great question. Thanks for watching.
What has happened to cb, why has it become so noisy. 60 years ago it wasn’t like that. You could easily talk from one county to another. At night you could easily transmit 30-40 miles with no noise. We would have to search for skip. Is it electrical noise from cars ? What makes so much noise on this band ?
All the electronic equipment that we have in our homes and in the outside world. Bluetooth,wireless , electric vehicles, cameras etc.
You should do the test over because your partner was not holding his radio straight up probably not the most efficient for maximum signal output 10 4. 473 Richmond california
True that didn't cross my mind. We are planning another portable hand held test. This time maybe at the beach so nothing blocking signal. Thanks for the comment.
Standing on a table where people eat is probably only the 4th worst thing that happens there.
Very true. Gotta remember it’s NYC
You should try in a less tree filled area to see the difference
Great idea. Thanks for the feedback. I shall submit your idea to the production staff here at the station.
Trees have no effect on a 10 or 11 meter signal. That’s 36 feet tall, these signals simply bounce right over trees. This is opposed to signals using 462 MHz which is in the 70 centimeter range. Those signals are simply eaten up by trees, leaves, and foliage.
Unfortunately, FM is worse than AM in terms of intelligibility when there are reflection interferences.
When the military gave up the 27 MHz band in 1957, no one had such high transmitting power as pirate radio stations do today, it was assumed that for a power of 2 to 3 W there would be no reflection.
In Europe, FM is used, but AM still works, FM gives a more pleasant, calm sound.
Moreover, it is better for portable stations because the FM modulator does not need to have high power and the portable station can produce just as loud modulation as an expensive and large base station.
Generally, FM modulation does not like noise interference, receivers with low sensitivity are recommended because the FM demodulator itself is an amplifier and amplifies noise in case of slight ambient noise, it is sometimes worth using RF gain to limit the receiver's sensitivity. But it's good to have a radio with naturally low noise and medium sensitivity like Yaesu/Icom etc.
In Europe, the 43 MHz band was temporarily allocated in Italy for civilian users to explore, but there was no interest even though the portable stations worked much better, there was no ionspheric reflection, a clean band, twice the range on a 25 cm miniature antenna (about 2-3 miles in an open field). It's a pity that such a good standard was abandoned.
It was supposed to replace the 27 MHz band because everyone was disturbed by ionospheric reflection.
Europeans were only interested in the range of large 27 MHz base stations and car stations, handheld stations were not adopted, they were expensive and had low radiated power due to the long wavelength and poor RF grounding. The antennas often broke.
Cheap slave production took its toll on hand-held devices.
In addition, the base antennas were unstable and broke frequently. Europeans could not afford to constantly replace antennas.
Moreover, the huge amount of interference from technical devices in cities meant that there were fewer and fewer CB 27 MHz users.
So there was no interest, also much better for small stations, 43 MHz. Portable stations were mainly used by teenagers and children, they were the poorest and rarest consumers. Production is unprofitable only for them.
43 MHz radios ruined the producers, even when they had slaves, they did not pay off, no one bought them.
Even ordinary CB production is unprofitable, the devices are too cheap, they are made by very poor communist workers who do not have their own house and live in the same room with many people. Due to lack of food, they accept any conditions to survive. This is what CB radio production looks like. In the past, they were made in the USA - Motorola, but today you would have to pay even more than $1,000 if they were made by an educated American. Maybe robots will help? A typical Policeman's radio made in Motorola - USA costs $7,000.
Thank you for the well educated comment. I have always used 27 mhz AM portable communication since I was young and with addition of FM here in USA I now enjoy comparing both AM to FM modes with experiments in distance and quality of audio and in terms of interference. I now enjoy FM over AM but it is still not popular here. I do not have FM portable unit yet but I have FM mobile unit and I have compared them to AM and SSB. Grazie per aver guardato il video.
Today's FM radios are much, much better than the old models from the 1990s. In the past, even in Europe, it was preferred to work with AM modulation because FM works worse. Today it is difficult to assess. In any case, higher powers of the same amplifier can be used for FM modulation. Modulation is always good.
FM is especially good for portable stations because AM modulation requires a strong modulator, which a walkie-talkie station does not have.
In FM modulation, there is no problem with microphone squeaking.
Good health and good luck!.
