The bltouch stops working due to a short circuit, maybe the problem is in the PCB extras! It burns the input on the motherboard, you have to rewire it and modify the firmware! take it somewhere else. A quick way to continue using the machine is to put an endstop in Z and cancel the bltouch
Thanks for the very detailed and informative review. I've bought one of these (the ATU-130) and I'm quite happy with it. It works quite nicely with my Yaesu FT-891. It tunes very quickly and has a pretty large tuning band. I work almost only portable and I don't miss the internal battery. I need 12V to power my transceiver anyway, so that's another pair of small alligator clips on the larger one that feed the transceiver. Easy and no need to worry for the discharge. Best 73s de F4LDT
As far as I know there are no manuals for these Chinese auto-tuners. I believe most of them (including this one) are all clones of the N7DDC design, and there is documentation for that here: github.com/Dfinitski/N7DDC-ATU-100-mini-and-extended-boards
Hi John, The 10 pin mini DIN plug is not a standard plug, For some reason Yeasu have "Flattened" the bottom of the metal shield (close to pins 8, 9, & 10). Off the shelf plugs don't fit in the Linear socket.
I am want to buy something that has lots of cores and lots of Ram to have big home lab for networking. to install ESXI v7 and EvE on it. Was thinking buying dl380 gen 10 with 2x 6152 cpu. But then I realized that it might be very noisy. I was wondering when fully on load does these server sound like jet engine?. like similar noise that is on 4:58 ? or it's because you are removing the fan? I am trying to understand if I place server in two rooms away from my bedroom and put on a heavy load will it sound similar to what is on 4:58 ? and if yes, can you tell for example what dbm is that noise so I would try to simulate and understand what should I except. Also I found hp z8 g4 with 2x 8160 cpu to be similar setup but with less noise I guess but I am not sure abut ESXI compatibility. sorry for my English ^_^ please advise .
I am considering buying the DL380 g10 with 2x 6152 CPU. will that be very noisy? I mean.... if I will put it in 2 rooms away from my bedroom. Will I be able to hear it while under load?
Oh my god. BeOS still looks good. I had the BeOS Window Manager theme on Linux for a long time. I think its still better looking then Gnome and for sure Windows 11.
@@john8520 Thanks John, I've been trying with 380°C, but didn't come off. Perhaps I need to be more patient, was afraid of damaging the board and stopped too early.
I have the MFJ-929 external ATU with the interface cable. I have to go into the Yaesu's menu and turn off the internal ATU and tell the radio I am using an external ATU. Now when I push and hold the TUNE button on the radio, the radio sends a carrier to the external ATU which then goes into the tune mode. It tunes and stops when it makes a match. Once matched the radio goes back into the receive mode. You did not turn off the internal ATU. Turn off same and set it up to see an external ATU. It may work with your LDG? Barry, KU3X
Thank you for this!! I have been manually going to CW when tuning, then manually switching back to SSB. This cable interface does that automatically. Be sure to select “external tuner” on the radio menu.
I just tried this trick. I shorted the 3 pins. The 4-5-6 and when I turn on the server gives fan error. The trick did not work on my DL380p G8, any help, which model is the one in the video?
Thanks for putting this out there. I just ordered the radio and was wondering what cable I needed to use my AT-200PROII. LDG’s website was less than helpful.
You're very welcome! I hope they can get their documentation together, it is a mess, and there are still plenty of unanswered questions. (Namely, how to use this with an amp.)
Did you ever figure out how to add an amplifier that also uses the radio's linear port? That's what I'm looking at also. I have an AL-811 with a Ameritron ARB-704 interface that also needs the linear port to work besides the AT-600Proll.
That’s a great question, and I have not. I don’t yet have an amplifier, but I suspect that splitting the port into two may be necessary. A detailed pinout of the “linear” and “tuner” ports on the DX10 would be very helpful.
@@john8520 I Called LDG today. Since the interface is using the linear port, the LDG can't use it. The LDG is used in the semi-automatic mode so you have to push the tune button on the LDG while you key the mic with the amp in the standby mode. You can't use the automatic mode with the AL-811 with the interface.
Thanks for video, I'm looking to do similar on the Pi Pico. Not sure whether the B does the same, but the Pico has a series resistor R14 into pin 3 (XIN of XTAL) - which means that this pad can be isolated from CPU and potentially re-used as a VCC pad for the new module. The 2 small value caps either side of the XTAL are to tune it to the drive circuit (inside the CPU), they are not needed for a self powered module.
A small note. The NTP protocol has a limit of 0.2ms on the local network. Using this protocol there is no particular point in making it more accurate than 200000ns
For greater accuracy, you can use a more expensive GPS receiver with a TCXO generator inside. In theory, a multi-band receiver with L1 and L2 bands with GPS+GLONASS+Galileo+Beidou should give more stable PPS than single-band GPS alone.
Multi-band, yes, absolutely. Multi-constellation... it's complicated. There's some research on the topic floating around out there already, but generally speaking the operators of all the different constellations cannot be depended upon to agree with one another when it comes to managing the clocks onboard satellites.
I thought the Raspberry Pi had an oscillator installed, but it turns out it’s a simple quartz. In this case, the oscillator can be taken of any size. On a simple quartz chronyc tracking I have Frequency: 1.600...1.800 ppm. Your Frequency is 0.17 ppm. We can say that your oscillator is 10 times more stable. Interesting idea. The ARM core Pi 3b+ has a frequency of 600-1400 MHz, this frequency is connected through a multiplier to the oscillator. Will chrony be more accurate if the frequency is minimal, since the error is 0.2 ppm * multiplier?
This is an excellent question! To be honest, I have no idea. I suggest asking it on the chrony mailing list, the developers are very responsive. chrony-project.org/lists.html
@@john8520 I think this needs to be tested experimentally. Chrony can monitor the processor frequency and takes it into account to make adjustments to the clock. I have not yet been able to run Raspberry Pi at minimum frequencies. There is little information on how to do this. Lots of information on CPU overclocking :) /boot/config.txt force_turbo=1 arm_freq=600 Attempts have not yielded results yet.
Back in the day there were people that ran BBSs out of their home and would set their PC up to receive calls during the daytime and when they came back home from school would switch it over to regular voice. That's part of the reason why the receiver is the one that starts the modem handshake and the caller has a speaker so you can hear the other end. Very effective at stopping telemarketers from spamming your message recorder during the daytime because they would think it's a fax number and block list it. I would get people calling outside of the BBS hours, and since they also had a phone hooked up to their outgoing line, after letting the PC dial and hearing a voice, they will just pick up the phone and ask for the BBS hours when they got my voice saying hello on the other end. Additional landline / phone number was $80 per month back then and my parents wouldn't pay for it. I also couldn't get them to upgrade to a 1KB/sec modem (14.4k baud) for $400 USD. Lots of students that were sick from school would dial into my BBS during the daytime and play multiplayer turn based games like The Exploration of Space (TEOS) and The Legend Of The Red Dragon (LORD). Eventually we did get a 56k baud modem for around $250 USD after they had came down in price, but by then BBSs were dead and AOL was what everybody was on, where it was $3 per hour to use the Internet and my dad was always yelling at me for racking up over $100 a month on the Internet alone, not including the $80 USD per month cost of the phone line that was always tied up when you're online. Gemstone III on AOL had massively multiplayer in realtime, not turn based, and that was just something that BBSs couldn't do.
It sounds so weird now but I used to hear that every single day it was amazing! R2D2 suddenly didn't seem so far fetched when we started using those things.
I love the Receive of the TS-830s over any Hermes Lite, Apache Lab Anan, IC-7610 and all that Knick Knack Technology SDR Stuff out on the current Market. The RX Sound of the Kenwood is way warmer. PLUS if it comes to maintain your Radio or Repair Work is needed to be done you be able to do it all yourself. There's is still Parts available in Electronic Stores. What I do not like on these Vintage Transceivers is the narrow SSB Filters with just 2,3 or 2,4khz TX Bandwitdh. Everything else on these old Radios is just perfect the Way it is.

tweak your drive controller, think of it as a receiver preselector, you may find the receiver and s meter is more responsive. expect to tweak the driver every 100kHz
