Would it be a good idea to put the dummy load at the feed point of the antenna down at the end of the coax? It seems that it would be able to reference the coax for any distortion. Or is it better to put the dummy load at the back of the radio?

"Compression lock" is way stronger than a button lock. You don't need to push the button to open it, and it's tip up. All the reasons it better than Milwaukee.

Until they put a driver on it, it’s still the Milwaukee Fastback 1505 for me.

I love the fastback with the driver for work and camping but outside of that i still want a decent 2-3" blade for edc. keeping it sharp is worth it.

I would love the Milwaukee fastback made smaller with a precisian screw driver instead of a full size.

I’ve had all the Milwaukee fastbacks . I like the new Dewalts better !

Thank you for the information as of September 2, 2024 there's a new update firmware 1.42 73, Jonathan

This is about hte worst antenna comparison test I have seen. 1. Placing two vertical HF antennas less than 1 m apart is disaster. 2. Testing the influence of the coax cables is meaningless. The differance in loss for 5 m cable at 14 MHz is about 0.1 dB. This is insignificant. 3. Testing the JPC-12 without splitting the ribbon cable and distributing the radials is a big disadvantage for this antenna.

thank you great video btw I think there was issue but on 1.42 it all sort out great vy 73 elan good job

One major thing I learned from this video is that more expensive radios and antennas doesn’t make for a better station. That using the Xiegu G90 with the JPC -12 can make for a very good station for less than 50% of the money spent. For travel to POTA Parks, lighter is better, especially when it comes to flying around the country on vacations. I also think your testing methods could have been easier and better by using just one coax cable, no outside tuner for less connections or connectors, where most of your loses occur in the field. I think the objective should have be to compare antennas and not antennas vs coax cables, those can be done separately in my opinion. However, with your test, I think the comparison could have been bias towards one antenna vs the other but you did a fantastic job in preventing that bias from coming into play. 👍

What does DPD improve ?

Just the fact that those bozo were complaing about tuning on frequency makes me want to tune on their frequency. Its not malicious interference most of the time, its like they dont know that often times you cant hear a station but they can hear you. Freaking idiots. Hams LOOOVE jumping to the "malicious interference" conclusion because they wont waste an opportunity to call someone a criminal.

looks like the isolation is only about 30 dB. Could be an issue if you are using a lossy rx antenna - which is an accebtable technique. Was the pre-amp off also on the RX antenna?

hi I also want to make a loop above my 250 m2 roof but raised 6 meters from the ground for my IC-7610 73 de ISØHMZ Luca

Did I miss you playing what the receiving antenna sounds like? Is the sound more pleasant? Can you hear qso's on the lotg that you cannot make out on the transmitting antenna? Would I rather listen to the receiving antenna than the transmitting antenna? Would I be able to complete more qso's using the transmitting/receiving antenna combination versus the transmitting antenna only?

Hi, what is the make and model of the matching box? Thank you. 73

Unfortunately this doesn’t show the signal to nouse ratio, which is the critical reading in checking out antennas. Not easy to do on dynamic signals.

Hi,good video, but what advantage is this feature, and how can it help me with the Acom 1500 amplifier, 73s from Rotterdam.

Planning on doing the same thing but not using a balun. Just going to use a little manual tuner in the shack so I can tune the receive for each band. 73

Thanks for the nice video

"100% auxiliary power" - impressive assuming all lighting, HVAC and SDR/logging computers were auxiliary powered as well - 100% means all power not just the XMITTER(s)

I've heard that v1.40 has problems with IQ through the USB2 port.

Wellbrook ceased operations in March of 2023 and Andy Ikin, the Brains of those fantastic Antennas passed in October.

Higher res recording would have helped my old eyes.I wasn't sure if you had to have the headers soldered. Anyway it's good to know about. Thanks.

I tried the dx commander. Reaply poor for me. So noisy. Now on an efhw so so mu b better.

I have been looking at this product and I am glad it works on a mac. Once I pick up a 9700 I can get this to do satellites. Thank you!

I thought this was not available to the US yet.

It’s a very nice feature and I do wish they could include your amp and tuner with the same thing. Note the cell service has been doing this for years with the amp.

"I'm just waiting for the matching box, stay tuned!" I see what you did there! ;)

I have inverted U, Inverted L with wire hanging down from other end. I notice lower the height , lower the noise. but, transmit get worse as it get lower height. My ANT is about 14 Ft high now, good compromise between Low Noise and acceptable TX . I operate from City with tight houses in neighbourhood. my dream is move to some place like where you live. I see under ground tornado shelter. I never saw those except in OK, KS AG6JU

Thank you for the purchase and testing. You could also try using the 7610 preamp with the LoG as sometimes it can make quite a big improvement on the SNR without increasing the noise floor much depending on local conditions. I tend to use my LoG with the 7610 on the sub RX exactly the same as your demo shows with headphones on, my DX Commander in one ear and the LoG in the other. It's really cool to hear signals move from one side of your head to the other as the propagation of the signal changes. Matt M0LMK/KI5GXV (LMK Technical Solutions)

How does the LOG compare to the Wellbrook? I have a Wellbrook, but fed with a different amp (the amp blew and I replaced it with a Cross Country Wireless loop amp, which works very well and has very deep, very sharp, nulls), and it is so quiet compared to my triangular loop (20m perimeter, with a 4:1 balun, fed at the apex - 6m/20ft agl, lowest points are about 3m/10ft above ground, so its sloping at 45 degrees or so). The triangle works really well as a TX antenna on 20-10m but is really noisy - rather like your DX-Commander (I suspect because they are vertically polarised, well I presume my loop is vertically polarised as it is top fed). I use an MFJ1026 noise phaser, with the active loop as the auxiliary input, which really helps to get the noise floor down. I've considered a LOG a few times and I can get 100-130ft loop in the garden (60x60x30x30ft, so in theory 180ft would fit but would be up at the house and too close to electrical feeds, etc.). I will be interested to see more comparisons as you get the loop configured properly. My area of interest for a project like this would be VLF-80m DXing, from a receive perspective, obviously. 73, and thanks for the videos - HNY '24, de G4UCJ - IO91ox

Excellent 💯👌

Disconnect the RX antenna coax at the back of the radio and see if it stops. You said that the RX antenna was grounded on that switch, I suspect the ground is picking up the signal now... I'm curious what the result is. 73.

Nice. What coax do you use out to the DX Commander??

I use a loop on the ground, great and easy to do antenna, In a pinch I've used them for transmit and they did pretty well for an antenna on the ground.

point of interest, lat/lon should be format 123.456W and 12.456N (not -123.456)

Great work!

Nice video! Thank you. What if the LOG is placed in the open field (no influence of building)? I want to test the LOG in my small garden.

Same here on my 7610.. Sometimes S2-3 with strong(er) signals.

You mentioned WSJTX is configurable for just one radio. You can actually make as many configuration presets as you'd like for as many of your radios as you'd like. Then it's as easy as selecting the config for whichever radio you have connected.

The leakage is many dBs down, not looked for the same issue with my FTDX101MP but it is likely to be similar.

Lost me at patreon. Won't support that company in any way.

Many congrats from user Icom-7300! de UA3NDX, Anton

Get a GPS dongle and make appropriate changes in the software and that will solve the time problem.

Now you're making me to see what this is! Haha. I'm not seeing a firmware update on their webpage. Hope you had awonderful Christmas.

Yep, lm told they doing one for the Kenwod TS 2000x, when they do, l,ll be buying one, lol

I just got this radio and really enjoyed this information. Thank you for your content in RUclips University

Voice level too low to listen comfortably. Sorry
