Learn the truckers hitch. Thank me later 73’s

I built one in 2012. It worked great. it was on a little 15 ft mast, but the FTB and gain made it shine. it stayed up until a tree fell on it in 2019, destroying it. Who cares about the sag. it wont have any bearing on performance. My MA5B shipped with the wrong hardware to assemble it, Be happy yours didn't.

how's the antenna? still performing well?

thanks! you got a bird flying in your shop at the end there

They should not be anything in the middle of the traps they are designed that way and with the correct distance apart they will never touch each other the way they are assembled

How’s it performed for you ? I’ve acquired one of these from a silent key, it doesn’t have about half the small x shape elements, I suppose cushcraft would send some. KC5UUS

Where did the video go?Can you upload a normal video again?

I would like to know how you haven't connected after the radio what comes next and after that one comes next because I believe that you have something not connected in sequence

Keep doing what you are doing. And on 20m band we have frequencies not channels .73 AE4OY WILLIE P.

With the 7300, i have mic gain on 50%, comp on 3 and Moni off, i use heil pr781 mic, if i use the hand mic i put mic gain on about 30% from Fred in Uk g4vvq.

Does it trip the 15amp breaker? What awg wire did you use? 12-2 or 10-2?

do you think this would work on a eave mount, about 5 ft up? eave mount has 6" lag bolts into house frame.

Could I ask where do you come to the decision for 7inches at the ele 1 and 9 inches for ele 3? If you want a centre freq of 14.025 the two elements are 9" , 14.175 the two elements are 8" and 14.300 the two elements are 7" How did you come to the decision to put 9 on the rear and 7 on the front elements?

I agree with the last guy the mfj is showing a nice clean 1kw. Keep in my your drive power is 50 watts which is what the Middle unit is measuring. I want one of these amps I love it does 6 meter. I'm wondering what this Amp pep output is with 100 watt drive??

So why not tell us what rotor your using?

I've had an MA5B for about 20 years and have been very happy with it. This year I had to open one of the traps and remove a lot of dead bug debris that, especially when it was raining, messed up the SWR. I run up to 600 watts into and have been very happy. It punches above it's weight class!

If you use WSJT-X use the “Tuning” button. It sends a constant tone.

You probably figured it now, AM will work.

Nice padded ceiling and light.

Amp and meter is showing right. Tuner display doesn’t look right. You should be able to flip it to RTTY mode and hit the transmit button. On the face of the radio to get a more stable reading on the tuner display

With your voice, I’d pull your comp down to 2 and increase your gain to about 20 and fine tune from there. Use the meter screen in the radio menu to see your DB output and ALC from radio.

I have had one for years. I have taken it on many mission trips and DX expeditions. Also I have used it for portable emergency operation Great easy to set up antenna

How well would you say the beam performs? How do you think the 12/17m rotatable dipole works?

My Tx indicator is Steady Red not green like the manual says I have the 606

Nice réalisation 73's Best regards

I am it the process of assembling this antenna. and my understanding of the tuning is based on where in the 20 meter band you prefer. in my case i prefer the upper phone frequencies (14.300) so i adjusted both element 1 & 3 to 7 inches DIM A & DIM B according to chart A . . If I am reading this correctly, regardless of what end of the band you choose both element 1 & 3 need to be the same according to chart A. As far as element 2 goes in order to get 205.5 inches i did not make the adjust on the ends (EE). instead, I needed to shorten the entire length by 1 1/2 inches and did so by simply loosening the hose clamps (411) and slid both sides in 3/4 of an inch. . . . . I look forward to any input or opinion that anyone has on this. Gary KC1OXM New Hampshire

the Mic setting should be 40% the compression should not be over 2, the meter on the MFJ 998 will not read over 100 watts, it’s plus 10 when you are over 100 watts, 80 watts 800 90 watts 900 if that make sense, your 998 and watt meter were both showing the same thing W4TSH

When you want to check your power out, go into rtty and key up. Look at your amp's and MFJ-998's meters as a comparason. If your seeing around a kw, that's your peak with that drive level. You can also do a good whistle in SSB and again look at the amp's and tuner's meters. I have the ALS1300 and I learned the hard way not to drive it with no more than the required amount to reach 1kw. In my case about 50W. Be very careful, the als1300/1306 is a kwSSB, 500CW and 400 digi amp. See my vid on the bench test I did and other 1300 operations. 73: Mike DE VO1AX

The meter on the front of the 998 will not read ssb signals correctly. This is a known issue at MFJ.

Nice!!!!!

To see voice peaks on SSB you need a very fast peak reading wattmeter. The large MFJ meter is pretty accurate and showing you with nice 1kw voice peaks. This is what this amp should do so you're not doing anything wrong. Ameritron recommends running the amp no higher than 1200 watts pep output for it to stay clean. These amps can do more, but your signal will be dirty if you push it too hard. Keep doing what you're doing.

Hi, I am interested in buying the MA5B, because your trap (coil) broke??

Great video, De Kg4Muk

Hi David, I run the exact same set up. I've only had the Amp about a month and have some of the same questions. I guess I'm wondering if the mic gain solved your problem. I don't generally use the alc.. I know it's what everyone does... I've experimented with it but usually just don't. I do run the mic gain much higher.. 40 to 70.. depending on if I'm doing dx or rag chew. My signal reports and audio quality have been good. I also see watt readings on the 998 averaging 200 something when the amplifier meter is reading 700. I'm just wondering if you've found any answers.. I've been extremely happy with the amplifier so far. Thanks, Roy

Very helpful for those interested in this antenna. Thanks for posting. Y

It’s a extra jam nut to jam against pipe so there is no NO slip de Kg4Muk

Hi David, Welcome to ham radio! You have a problem many hams would love to have! You can afford equipment many experienced hams can only dream of. Most of us learn equipment one piece at a time with plenty of time in between each purchase to learn things one by one. I would suggest you turn off that beautiful amplifier off and break out the manual for your IC-7300 first. Learn how adjust mic gain, compression and ALC. I WILL cut to the chase for you however. The problem you’re having is you are already using the ALC control on the amplifier before you have established basic settings with your 7300 and your amp. You should NOT be using ALC control on the amp at all initially.The ALC is meant to turn your power down in the event of operator error. I understand there are not many good explanations of how the ALC works even in the Ameritron manual. When you turn the ALC on the amp all the way up to a 10 you are effectively turning the ALC OFF. Forget the blinking light at this time. Clue: you have the ALC set to 2 so it is making your power decision settings on the 7300 meaningless. That’s what the ALC is meant to do! Turn off the ALC by turning the knob all the way up to 10. Turn your mic gain all the way down or OFF. Use FM or RTTY mode to generate a constant carrier. Start with 25 watts. Use your MFJ peak reading watt meter. You should be using a dummy load. Put the amp in standby and push the mic button to key the 7300. You can also use the transmit button just under the power button on your 7300. With the amp in standby adjust your radio output to 25 watts. Turn the amp “On” and check your output power. Gradually turn up the power on the 7300 til the amp is putting out 1200 watts which on that amp is the maximum LINEAR output. Now you can switch back to SSB. Turn mic gain up to 65%, compression at 2 or 3. Now when you are transmitting, speaking into your mic, your amp will be swinging up to the max 1200 watts. NOW you can use the ALC control on the amp to turn DOWN your power swing to whatever power level you desire. If you want to put out a clean signal and make your amp last a long time you can turn the ALC level down to where you are swinging 1000-1100 watts. When you change bands you will need to repeat this process as power output will change on various bands. Run your equipment very conservatively until you gain more experience. That amp will easily exceed the 1500 watt legal limit so keep an eye on that watt meter! Hope that helps! 73’s catch you on the air, Your friend, Vic AE0IN Parker, Colorado

turn your mic gain up to about 30% also turn your output power to about 75% I keep my ALC at 4 The Compression needs to be about 2, turn Monitor off De KI5BZO

I used to own one of these and sold it like a total Moron.. now I am saving to get another one or get one used if one goes on sale.

Mic gain is all the way down so Bring that up. Looks like the digital meter is in front of the radio seeing the drive power (radio power) and the analogue meter in front of the amp seeing the full power.

Your mic gain was really low. 1%

Glad I was able to help you out and save countless hours of aggravation. Best to find it now before it goes up then have to take it down again. Hope all worked out well....

Find some help from a ham that knows what they are doing. I ran the exact setup for a few years. Never needed more than 50 watts of drive for full power on all bands. Cleary you are putting out about a 1k but please turn up mic gain to at least 10 to 15. Turn on your compressor but to about 5 and get a good ground.

Thank you very much! This was very helpful and interesting. 73, Steve, AK4R

If you are calling cq cq cq the first thing you are supposed to do is turn the mic gain and processor wide open. 59 59 say again? In the last year or so scientist have come up with a marvel formula called Ohms Law. Every ham alive knows this by heart. Its amazing because it allows you to calculate power out using voltage and current and you can estimate efficiency based on the device you are using. Voltage times current times efficiency in percent. Example: 50 volts x 50 amps = 2500 watts INPUT, 2500 watts x 50% efficiency = 1250 watts output. That amp has 8 MRF 150's. Figure about 150 watts per device plus or minus a few watts. 150 watts x 8 devices = 1200 watts out. In SSB you need a peak reading meter or oscilloscope to catch the peak of the power envelope you are actually getting too. This is incredible easy to see on an O Scope and you can see that as soon as you utter anything into the mic you get full power out. It's much harder to see on a watt meter because of the meter movement itself is slow reacting. Special circuitry must be put into place to drive the meter quickly enough to see PEP. You will never see the correct power out in SSB using an average reading meter.(you hear people talking and sustaining their voice to get the meter to read higher) Watching your video its obvious that the MFJ is pretty close to being correct. (Mic Gain) Watch your ALC and never go out of range there. (Processor) On the compression meter stay below about 6db of compression. It doesn't take much. It might not be a bad idea to invest in a tune up pecker if you cannot use the radio to do this. A gent named Dan Cox in Houston Texas that talks on 3870 at night or 3900 in the mornings makes these if you are interested. K8woz. Tell him JimmyWatt sent you. 73's and good luck

Hi folks./Dave your drive limit of 60 watts drive should put that 1306 at or above legal limit. Everything should be adjusted using a dummy load! PS don't depend on 3 different watt meters if you have the $ you should consider getting a LP-100A wattmeter they run very accurately and can handle more then legal limit. 73

Avid 7300 user here, all looks to be working fine to me.

Hey David.. Seen mic gain at 1%...did you try turning that up?? That’s low if that’s correct... hope you get it working.. The 1306 is a wonderful amp!! 73. KB8MCF

Hi David. I have ALS-1300, which is the same amp as you have but without 6m. Mine gives out around 1200 to 1300 Watts. I don't limit the output power of my transceiver. I keep my transceiver at the full output, which is just under 100 Watts. No keyer is needed. You can either whistle to your microphone, or use AM or FM. Trust the reading of your external power meter that you have on the very top. I do see it reading over 1000 Watts now. 73 de Marvin VE3VEE

Did you get good SWR? because I have been fighting with it. I see you got two different messuments for element 2 and 3. The tuning chart says 8 inches for the general portion of the band but those 8 inches are for both element 2 and 3. Im just wondering if I have mine set the wrong way. Let me know Im having a heck of a time tuning 20 meters.
