I was shocked that the Uniden sounded cleaner and easier to hear. I didn’t see very much difference in the signal gain. The Connex showed a hair more gain on the meter but if I wasn’t watching the meter I say they were pretty equal with the Uniden sounding better
Wasn't too concerned with the sound. I had the mic gain set in random positions and just happened to have echo on the Connex. The main focus was to take two radios with identical Peak outputs, but significantly different average power readings and see how that translated to actual signal strength. 2-3 S units doesn't seem like much, but it's the difference of being heard and not. Of course, adding an amplifier will make the difference between radios far less noticeable.
Please enlighten me sir. So it means that aside from the right dk setting for a particular amp., let say a kl300p that says in the manual of 10 watts max input, is that pertaining to dk, average or pep? I really would appreciate an answer Roostet sir.
@@Rooster_Radio ok cool deal thanks man I’m fairly new to tube amps, I recently got a line section and a couple slugs and got that cheap dosey and jumper out of my station. Idk if il get the pep kit or not so it’s bird for now lol
So, would peak power be better used as an indication of how the radio is modulating or perhaps relative to how "strong" the audio is? The measurement of peak watts seems like it should be relevant to overall setup but be just another data point to be considered when trying to get a well balanced station. Thanks for demonstrating it.
One thing he did say about the export on the right... He said 20 bird... Looked more like 18 to me.... But in any case.... This test has already been done and I can tell you that an export radio... We'll back down a few watts Once pushed into an amplifier... Which is fine.... On the other hand the Cobra or Uniden. Doesn't back down... Which is why serious operator running power choose Cobra
@@Rooster_Radio ok... But like I said.. That radio will back down .. When you put it into a driver... So to be more like 18 or 17.... Which is fine.... Stickman of no name amps did the test long time ago it's on video on his channel
Interested also. The cobras and unidens have a modulation transformer and the exports have a different modulation circuit that supposedly isn’t as “good” lol. And the cobras l/unidens would swing full output basically no matter were the dead key is at. I’ve been told that the 29 currently has the best audio circuitry for loudness when modified (for a plastic radio) I find this stuff super interesting.
I stand corrected sir. You mentioned that the average is the one that may or may not kill an amp. So meaning to say, if I'm putting around 4 to 5 average input in a kl300p, the amp will still be safe either you've got a 15 or 25 watts pep input into it?
deadkey or carrier is more related to average power than it is peak. All power levels are relevant. Peak, Avg, Deadkey, with deadkey/carrier and average power having greater effect. That amp you are speaking of is low drive and ideally should have no more than 3 watts deadkey and according to their suggestion 10-12 watts PEAK. You can get by with a little more peak power, but do not exceed the 3 watts deadkey.
Pretty cool video it sure is a debate among some operators and very confusing for the people who are just starting out with CB radio equipment or even rekindled an old hobby .. Bird 43 is not the best choice to measure AM modulated signals , it will not measure the average power of this waveform accurately due to the fact that the peak to average power ratio of this signal is not zero?.. Now that's not my statement and I don't know enough to comment on it but it's on frequently asked questions on Bird website They suggest using APM16, 5014 with a B series element APM10B or equivalent DPM element this combination will provide the average power of this modulated waveform ??.. I'm really confused about all this and glad you're showing your test results with pros and cons which ever form of measurement Honestly I really don't know if ones better than the other... thanks
I would not say it absolutely doesn't matter. It serves a purpose. IN MY OPINION, peak is best served to measure what % "modulated" a signal is. And although it appears that average power carries more weight and influence, peak power is still relevant and should be considered.
Bird watts.......end of story .... Sorry to all you Claiming you're doing a 1000 watts... Cause we know you're using dosy watts... And you wonder why you get crushed.. When somebody real comes out there talking on a 1000 bird....
I can for a fact tell you in regards to a 2 pill 2879c the Connex will usually get around 200 avg while the uniden will show 150, but I'll do that test for sure. I'm a uniden/cobra person primarily
If this video doesn't convince that Average power isn't "useless" then I don't think much will. It's obvious that it's a relevant and significant measurement of useful power. More current consumption and more signal, but as.always... to each their own
the bird 43 CANNOT read a modulated waveform accurately. the avg readings people look at while modulating are not accurate. you must use a pep kit in pep mode to read a modulated carrier accurately. the bird 43 was made to read a carrier and nothing more. straight from bird: "The model 43 is not the best choice to measure AM modulated signals. It will not measure the average power of this waveform accurately due to the fact that the peak to average power ratio of this signal is not zero".
70% of bird 43 owners don't even know how to use a bird meter correctly. you need to use the lowest power element possible to give a near or full scale reading with the meter lying down flat, not standing up to be as accurate as possible. the bird 43 has a +/-- 5% accuracy AT FULL SCALE, not bottom, middle or anywhere else. so when you take a reading at the bottom of the meter scale you can have up to a 25% inaccuracy. example: reading 500w on a 2500w element is wrong, you will get a false reading. 500w? use a 500w element for an accurate reading. the elements have a degree of inaccuracy as well so that adds to the equation as well. the detector diode in bird elements are not temperature compensated so you can get different power readings on a cold day compared to a hot day. and fyi, bird meters are not lab grade instruments. its not the holy grail of perfect accuracy everyone makes it out to be. it was built to be a very rugged, heavy duty, self serviceable meter that gives a usable, FAIRLY accurate reading good enough to use for hobbyists and commercial broadcast applications.. 5% is a big variance, especially the higher up you go in power. they also think pep is "fake watts". the most ridiculous statement i have ever heard.
