The factory SP-40 speaker looks like junk. Not worth the $120 ($70 with radio) price. Thanks for posting what it looks like. I will buy a different speaker for my FT-710.

or just use a R12 hydrocarbon replacement. Much easier.

How tight of a fit should the cervo be

Band center is 465.14375, I'm going to build one of these - thanks - Question: Can you give measurements or diagram for the critical lengths and solder points? How to measure impedance match, or is that derived / guestimated by swr reading alone? Thanks!

Rick, thanks for the unbias not sponsor video opinion. My old Chevy Silverado had an mechanical fan it worked well. Those electric fans are just more electronics added to the electric system.

How do you hook up the frequency counter to the radio?, i have a stalker xx 20 cb base radio.

please show your VNA setup for this demo

how long is the pvc?

will this work for 2M 70 CM (please excuse my ignorance I am a newbee)

But, no retention BEHIND the beadlock ridge.

This explanation is amazing! I’m studying for my technician and general at this time. Thank you!!

I made this for my first antenna build. Thank you for the concept. I have to say it does seem to have a directional aspect to it and I have no clue about gain is it seams to have a little more reach to the north when pointed north compared to a 6db gain omnidirectional antenna I bought. Slight tilt maybe 5-10 degrees helps as well.

What are the lengths for a 70cm dipole please?

Hi don't know if you are still on this channel, but I found in someone's loft a old skool astro playing, from way back, and I was happy to say that I was able to get it, so at the beginning of your video I thought you was going to BRAKE DOWN a an original, but I should have known better before I run, as soon as it starts I could see straight away your a man that can, sorry. And I loved this video, so interesting and educational. I'm in LITTLE OLD ENGLAND, and just saying hi, I'm a 11meters nut, But still at the thinking stage of becoming a HF person, lol.one day it will happen, been speaking all over the world with the astro plane, and the USA has been coming through for bout a month now, for a year that's meant to be one of the best cycles , mother nature took her time ,But that's RADIO and why we still do it. Thanks for the video again. Alan. CT 48/70. 26 division. 73 s 🇬🇧🇺🇲🍻💯👍

Aren't strippers expensive for this? You need a pile of sma bills to get then to do anything.

I am having an issue getting solder to stick to the copper Romex. I've gotten it plenty hot. Idk what I'm doing wrong

What kind of car? My old Lexus has a trans shift cable of sorts but it’s all in engine bay and trans tunnel

I have made the change of speaker for the recommended Visaton FSR-7, I have been able to eliminate the metal part by hitting a nut with washer with cyanoacrylate in the 4 points necessary (2 to the left and 2 to the right of the front). The 2 screws below are placed before closing the enclosure. The sound has changed substantially for good. Greetings.

Excellent video and instructions and these antennas are awesome so easy and fun to make. Easy to tune as well. Between 1.1 and 1.3 to one in the 2 meter band . That's better than some name brand antennas.

I have another new idea. You can suppress the metal part simply by hitting Cyanoacrylate a nut with washer to each of the plastic tabs of the front rack. Thus you can hold it with its original screws. This is what I will do as soon as I receive the speaker I have purchased (Visaton FSR 7).

Thanks for the video and the experiment. Well, the problem that I appreciate is that this speaker has filtered frequencies from at least 700 Hz. and this prevents it from acting as a true exterior speaker. Frequencies between 100Hz. and 700 Hz. they will not be benefited by the quality of that speaker. Another solution is to connect a self -amplified speaker to the headphones connection. There the range is total.

Great video, will have to try and make this. Thank you.

I've been using a Yaesu SP-10 speaker. It matches up with the 710 very nicely. I think it sounds and looks better than the included SP-40. With the AESS function, when using a different speaker, the phase needs to be checked to make sure the two speakers don't cancel each other.

what do you mean by jumper, what coax size and what connector on it, and how long, is the connector for swr pl 259 or tv coax or cb

I'm a licensed ham and do not really participate in citizens band other than leveraging it for propagation via software defined receivers. There's one more thing I can say that citizens band operators absolutely dominate us hams on. That is that they get on the air regardless of conditions. We hams tend to be super quiet and not out there shaking the bands up. Meanwhile 10 looks closed on the spectrum display. Hop down 1 MHz and it's wall-to-wall spikes. Cb guys are some of the greatest hobbyists out there.

I have 3 questions. First, would there be a problem building this out of bare copper wire, rather than insulated? Second, rather than solder the feed wire to the antenna, would there be a problem connecting it with a set screw type barrel lug, that would allow you to move the feed point up & down easily to find the 50 ohm sweet spot? Third, is there an easy way to measure the 50 ohms impedance with common tools? I'm assuming that a common hand held multi meter is only going to measure resistance & not reactance.

Sure the engineers were thinking people would change out their batteries before they pop 😂

Now 2 years after posting this, would you have done anything differently? Also when you made a bend at the top, and attached the string, did the meter change at all?

Thanks. Between this and book pdf i found i can start to diag this strange carburetor

How is the water pump turning with no belt..??😂.. i think i know...

Would 12 gauge Romex work any different than the 14 ga? I only ask because I have a bunch of that already.

Thank you for the knowledge. the thing i missed about the stub!

Had one I ran forever. It just kept going an ran well

One of the best 6 cylinder engines produced in America. Used on the original Mustangs, putting out 120 hp, that little engine would make the Mustang burn rubber in 1st and second gear and blow up the standard 3 speed manual transmission on many.😊

Where can i order gasket to replace my old one

Can you share what the diameters are of the primary Venturi and throttle bores? Ty.

@Ricksshop Okay, for the heavy duty , how about a home brew three or four element gmrs yagi? I convinced some friends to get into gmrs, but the 4 watt ht barely makes 2 miles, line of sight to the inlaws. This j pole or the mini yagi might work.

This video is just what i was lookin for .. is there also a timing mark under the ip cover..wish you would have went into detail on that to or maybe that is irrelevant..just tryin to learn

I purchased one of these carbs to try out the annular boosters on my '66 Mustang. After a year of messing with it, like all of these videos showed and adding a phenolic spacer, I decided to go back to my trusty Holley 1850. Heat soak was NEVER an issue with the Holley, with no spacer. Much like an Edelbrock carb, I think the problem with the Summits is that the aluminum body and integrated float bowls transfer too much heat. With the a Holley there are a couple thermal brakes in the form of gaskets between the body and the metering block and the between the bowl and the metering block. My Summit went on eBay and the Holley is back on the car. The car dying in traffic made the Summit dangerous.

Looks like where you welded the pieces end to end could be a potential weak point. Should have added a piece of flat stock lapping over the butt weld by at least 12” either side

I have one of those spectrum analyzers and I never knew it did vSWR

Can I get the specification for that antenna, please an thanks, watching from Jamaica west Indies !!.

I recently p bought a summit carb the 750 had two excelerator pumps on it a double pumper. I was on a stroked 360 it's a 408 now it has a truck flow heads on it The carburetor was it ran good it was a little bit powerful but it was kind of a dog and I like my Holly spread board a lot better and all kinds of power so I called summit and told them that I want to send the carburetor back to them yhe told me i could try rejetting it and add larger 60 cc pump on the secondary they have a kit that has a new pump housing and accelerator pump and a new spring forward and the hardware to operate it so I bought two of them and put one in the front of one in the back and then I took a drill and drilled out the offices on the accelerator pump squirters are jetted it up but almost five complete sizes from where it was and I'll tell you what this carburetor runs like good now it has so much power is better than the devil bumpers I have

I have made this from 450 ohm ladder line, it was called a sloppy J, I put this in a pvc tube and used that as my first 2 meter antenna for at least my first year, now I use the same antenna as fieldday antenna. 73 pd5rv

Thank you Rick! Great information about this old but very functional antenna. Just bought 40,20,17, and super 15 coils today from my local CB/commercial radio shop. They did not have a mast though. I have a 2005 F-150, where would you mount these? NMO mount on top or stake pocket drivers side or my aluminum toolbox? I’m looking for ideas: first though I have is 22” mast on top of my truck where the NMO is with spring. That is contrary to the antenna current theory, so I’m not liking it. Next idea, stake pocket with a 90° mirror mount with 54” mast, spring on bottom, QD on top, with the resonator on top of that(probably the best plan). Third idea, use same as second idea just mounted on the back of the truck toolbox. It is aluminum so I would put a piece of Steel on the inside to beef up the metal. 4th idea, mount in my 2” receiver with 3/8-24 lug, with the same spring, 54” solid mast, QD, then resonator on top.

Great video! Just curious, how did you come up with the 5/8 inch feed point?

Wow great info

It looks like you have interference on the 40m band probably from your power supply. I have exactly the same spikes on 80m band with preamp enabled. Anyway I'm happy that got FIELD version as I see now what the crap is that original speaker.

I would love to see CBers DIYing their antennas. There are lots of overpriced garbage antennas out there, you'd be surprised how effective 6.5m of wire and a homemade 49:1 can be. You can buy a $200 antron, or drop $10 and an hour of your time on something that works better anyway. Also directional antennas you can build yourself as well. I've never tried building a yagi for anything bigger than 2m, but the tape measure abomination I made worked very well.

thanks but went got 1 out a 95 mercury cougar same 1
