Great video! Very well put together! I’ve been watching a bunch of your stuff. I appreciate the time you took to put them together. They help a lot!
That meter looks nice! Always good to see practical tests. Great video as always my friend!
Thanks Chris.
Thank you for this video. I just started this hobby in January of this year. I am 46, I got a lot of work to do. It's killer people like you that make this hobby so exciting. It would be a pleasure to meet you. Have a great day!!!
Well thanks for your kind words. You keep watching, I'll keep making videos.
I'm here to learn about dummy loads but, I have to agree with your comment about the antenna switch. I bought two of them, one for home, and one for my RV setup, I was genuinly impressed by their weight and ruggedness.
Well if you want a dummy load, you have found the right guy, er, channel haha! Thanks for stopping by. 73
Thank you for the review, you did a great job.👍
Every ham should have a dummy load, when things aren’t working as they should, dummy loads are one of the easiest tools to help locate where an issue might be. The small plug in ones, on low power, with a back to back connector are really useful when out in the field. Great review thanks. 73 de M0AZE.
I agree. Thanks for watching.
New to your channel and have watched a lot of your videos. I appreciate the content, and esp liked the ham it forward vid. Excellent stuff.
Welcome, and thanks for watching. Gotta pay it forward when you can. 73
Very interesting & informative. Just got into this hobby, & I really liked the info that you've provided. Stay safe & healthy...
Welcome to the hobby and thanks for watching.
Good info Mike. Thanks and stay safe.
Thanks, you too!
Thanks Mike, once we are out of lockdown here in ZL i guess i will be ordering some of this gear. The wife shutters everytime i watch your videos as she knows i will be spending 💵💵💵👍
You can't even order stuff through the mail? Tell your wife I'm sorry haha!
Your videos have inspired me to get back into the hobby. I dug my radios out of storage today and hooked most everything back up. My issue is that I need an antenna and some coax so I am not back on the air yet. It may take a while as being retired means limited income which means having to save up for purchases. But I WILL get back on the air. I'm interested in POTA as there are no mountains in Florida. And POTA sounds like something I can do with the wife. Thanks again Mike for doing these videos. '73 W4MKH
That's great to hear, thanks so much for sharing that. I'll bet you're itching to get on the air not that you have most everything hooked up? You don't need anything fancy for antenna or coax for hf. There are lots of affordable options out there, or you could always make your own. Hope to see you POTA'ing soon! 73
Nice video: There is one thing that is important on your switch ! The port to port isolation. Little else matters!
Very true, and I don't think it is intended to be used the way I was using it with multiple transmitters.
I like that antenna switch 👍
Its a beast for sure.
Very good information here. My IC-7100 has a build-in power and SWR meter. Very handy. My HTs do not, so a power meter would be helpful. Also, my antenna switch has a ground connection that grounds all the antennas. Great when storms are nearby.
Thanks David. My 7300 has the same feature. Still nice to have these tools in the arsenal. Especially for the VHF/UHF radios. I still need to work on something for ground. I don't have anything grounded right now. I definitely unplug everything when a storm is coming.
I thought you said “Get your Balun” I was like OH HERE WE GO AGAIN!
Hahaha! No we will not go there.
Wonderful demonstrated 73 vu3wrr.
Thanks for watching.
Hi Mike, K8MRD,
I listen to your advice and bought me a K-Po digital SWR meter.
I always thought that the wave was 1: 1 so not 1: 4 was
Now i kow😉
Thanks

Thanks for sharing
great video. MFJ has great stuff. what showed is a must for most stations. maybe go to MFJ and do a video with them at their factory. a lot of MFJ is done in the USA . 73's
Thanks for the practical demo of this gear in series. Very cool stuff, Mike. Not only do we see how the stuff works, but we get a review of the TX power levels of those 3 rigs. Oh and why's your video voice radio-like? 😄
Thanks Dennis. I was surprised the x5105 was putting out more than 5 watts. Kinda already knew the 819 was all over the place with its TX. I just naturally have a radio voice. Too bad I found my calling so late in life haha!
Nicely Done 73’s W1FYG
Thanks Don
Howdy Mike, you could put an a/b (2 position) switch in front of the 4 position so you could easily switch between the HF antenna and the dummy load. Or if you have a three position you could have HF/V-UHF/dummy options. Thanks for the vids! KY4CKP
Yeah I was thinking about doing that. I do have another antenna switch. It'll prob work its way back in the mix.
I had bought the MFJ-849 and the HF side was defective right out of the box, so I'm waiting to see if they send me a new one or refund it because they are out of stock.., the UHF/VHF worked as advertised, the antenna switch and dummy load are awesome.
I believe another youtuber (maybe hamradioconcepts) found that a similar watt meter was unable to pick up Extremely Low powers. Thanks for video!
Well this one does just fine. Thanks for watching.
@@hamradiotube Meant in regards to you testing the L1 power on your Yaesu displaying no power. Could have been under the mW threshold.
@@ThyBlight Ahh, good point. Could be. I'll have to check the specks for sensitivity.
A good antenna analyzer, from Rig Expert for example, compliments these tools. Btw, measuring output close to the rig does not tell you how much actually makes it to the antenna (attenuation) due to feed line loss. You have to measure at the antenna. A dummy load is great. I just bought one. I have an old 2-way switch, cheap. 20 bucks. It works. Another one I had had a short somewhere and kept blowing my fuses on the Base-T 12V input for my remote antenna tuner. Oh well. That's all part of the hobby! 73! SV0SGS.
For sure. I have 2 analyzers. Wasn't looking for how much power is going to the antenna with this video. This was purely a what is my radio doing test. That would be a very vast test given all kinds of different antennas, coax, length, and a trillion other variables. However, having an analyzer and a good match to your antenna will give you a good idea of what you are putting out.
@@hamradiotube I agree. Keep up the good videos! 73 de David SV0SGS
Great well done! can you tell me how you have each one connected in line of order? I.E. Radio - wswr - ATU - switch box- antenna. thanks
In some instances if you plug your radio into a power source you will get higher power output compared to using the radio's battery.
Yes you will. I tried that w/ my Yaesu and it still didn't register on the lowest setting.
Low settings on a hand held are usually 1/2 or 1/4 watt give or take depending on radio, I would guess anything under one watt would not be too accurate on such a meter, But it gets you in the ball park. If you were an electrical engineer and really needed to know the exact watts then a Bird ohm meter or equivalent testing equipment would be needed. Keep up the good work.
Are you trying any activations during this time? I have actually hunted my first couple POTA contacts recently. It has been fun, anyway stay safe and look forward to more POTA videos eventually!
I haven't in a couple weeks, not because of the virus, the weather has just sucked lately.
Was just thinking that you're probably not getting full power out on the HTs because they're not plugged into external power supplies. Take the Yaesu VX-7R for example, you'll get full power out when running off the cigarette lighter power adapter or the external power brick. Not all radios now will work while plugged into the power brick though.
Yeah to a small degree. I did plug the Yaesu in and it was slightly better but not enough to make a difference. I'm actually curious how accurate this meter is at lower wattages. It's certainly "good enough" and most ham gear isn't made to professional grade, so there's that. Thanks for watching. 73
Very informative, thank you. Is it possible that the radios that are showing lower output than expected are doing so because of coax losses? Is there a test you can do with your watt meter to determining feed line loss? If so; can you demonstrate the test? Thank you.
On vhf and uhf yes. Search my channel. I did a coax loss test some time after I made this video.
Thanks, I’ll look for it. Glad I found your channel.
Can I ask what base antenna you are using?
Hi Mike I was just wondering on the antenna switch can you use for different antennas and switch between them using one radio?
K1DXN
yes
Yes, either many antennas for one radio, or many radios for one antenna.
73 Thank you very much for the test.
You're welcome. Thanks for watching.
Hey nice video, i have a question i’ve been looking for this digital meter i seen 2 in the internet, MFJ 849 or NISSEI DG-503? Thanks
Thanks. I don't understand your question though.
Hey sir, how are you? As always you make great videos. I was curious as to the bench you use. Is that from harbor freight? I am needing something like that but was wondering how sturdy it is. Does it wiggle side to side or anything? Keep up the good work, and God Bless de KG5DGO
Hey Steven, thanks for watching. Yes, it is from my favorite store in the world, Harbor Freight. The Bench has been great for me. No problems at all. It's actually surprisingly solid. Take that with a grain of salt of course, it is Harbor Freight we're talking about. But for what I use it for, I'd absolutely recommend it.
@@hamradiotube my boss was looking at some of these for our water plant lab and it needed to be sturdy so the chemicals and burets were stable so they wouldn't be knocked over with a slight tap
What's the Port Isolation on that Switcher ? .... It's a wonder you don't fry the front ends in those recievers.
Not sure. I read an article in one of the recent issues of QST on these switches and it gave them very high praise for its isolation.
We often hear a debate about average/RMS power vs. pep when it comes to measuring power out. If you had your choice, would you prefer something that show pep when in on ssb? I notice the meter you demoed does not measure pep. When would you want it and when is average/RMS preferred?
I really don't care about any of that stuff. I just want to know what my radios are doing at their output stage. This meter does just that.
@@hamradiotube it averg on that meter
N MR Stubbs is a reall nice
I got to go visit again I'm about 50 miles from mfj
73 n9prf
What digital swr meter is suitable for FM 88-108Mhz measurement?
I have no idea. I'm not in broadcast radio.
WHAT COAX ARE YOU USING FOR THE JUMPERS FROM RADIO TO DIGITAL SWR/WATT METER
Looks like RG8X.
The question is, how well is the MFJ wattmeter calibrated?
That is a very good question. I don't think you'd want to do any real precision measurements from it but it's close enough to be reliable enough in the shack.
@@hamradiotube you can probably get it close enough but for a range like low, mid and high. 10W, 50W and 100W.
Nice toys and I Love them a lot! CQ ... CQ ... This is JZ04APO from Indonesia.
Thanks for watching! I need to get Inodnesia in the log. 73
I like your earrings
thanks, me too.
Why buy the separate dummy load if the MFJ-949E you have there has a built in dummy load. Unless you go over 300W, you can just use that couldn't you? Enjoy the videos. Thanks.
Because this does HF-UHF.
Excellent answer. That MFJ-849 has been on my list for a while, I may be stimulated to by one today. Thanks
I wish MFJ would have made the digital meter with a better peak value, at least 2 kilowatts. 73
I would imagine this was cheaper to make than a full power meter. Plus the amount of people with amplifiers vs without is prob pretty low. Who knows?
I never take the plastic protector off anything.
Why not?
@@eugenecbell Its like peeling a scab, dont do it. Let it fall off when its ready.
It is like sleeping with your wife on your wedding night, it is now yours and there is no longer reason to keep it in a chastity belt.
OMG thats an abomination.
Tnx for video.

You are welcome!
4 Da Utube algorithm!
thanks
I want one so bad.. They need constant power though, don't they? I'd like to be able to use it on my mobiles.. KE8ODY
The meter does need a constant 12V yes. It draws so little power it doesn't even register on my Powerwerx watt meter though. It doesn't need to be on to TX either.
MFJ = More Fucking Junk. However, MFJ had this unit made for them. Then, MFJ had their label printed on the unit. My two DG--503 are very accurate, and I am pleased with them.,
Well thanks for coming on my channel and thinking it's OK to drop the "F" bomb. That is totally in line with trying to be a good steward of amateur radio. I remember learning exactly that in my Technician test. Good job at showing others exactly what not to do.
@@hamradiotube You're more than welcome, old man. It takes a lot of guts to wield free speech and show true freedom of expression. However, the truth is the truth, and, there is no denying that, now, is there? Keep up the good work. de Tony, g6ypk
@@susanhodges9447 I'm all for free speech, otherwise I would have deleted your comment. Instead I chose to leave it up. I just try to keep my channel G rated, as if we were on the radio, you know.
