Quantar / AstroTAC v.24 board
zhlédnutí 512Před 2 měsíci
The second revision, 2024-05-12 of the board. I discovered an error in the datasheet of the MAX3185 where it has pin 16 and 13 swapped. Other than this, it works as intended. I will have to respin the PCB and try again in another week 🙁

How the last real estate agent left my house.

It was left open and with the backdoor just swinging in the breeze. The neighbor called me asking why it was like this for two days. They make over 10k for this incompetence.

Short little video showing the Anderson Power Pole connector installed on my s2000 and how I modified a set of jumper cables with it as well. These are the SB50 connector series and each color is custom keyed to only fit with the same color.
FPP on a Model II ?

Can you Front Panel Program (FPP) on a limited keypad (Model II) XTS? It would appear so, but you cannot set a channel name.
Why loads on unused multicoupler/wilkinson divider ports are so very important.
zhlédnutí 265Před rokem
It’s common for me to see these ports left unterminated at many locations. This is a quick demo with a vna snowing how this effects the input return loss. If you’re using a precision matched pre amplifier, leaving them unterminated will negatively affect performance.
Transfer switch for parallel generators
zhlédnutí 1,5KPřed rokem
This shows a novel way to parallel two predator 9500 inverter generators safely and connect to load via a service rated whole house transfer switch. Note this will not work with other non inverter generators as they cannot self synchronize.
Why a 208/240v UPS doesn’t give 120v
zhlédnutí 342Před rokem
Recently I bought a new UPS (an APC SRT6KXLT) to run my computer and routers off 240v rather than 120v. Initially some probing with a voltmeter showed 120v between ground and both outputs. As this made no sense, I researched it and found out why. The ups battery negative is tied to its neutral internally, and this causes some strange reference voltages when using typical US residential split ph...

As an emectrical engineer. You made me feel so stupid.. Mannn you have done an amazing job. I don't have the courage to put so much effort into it like you did

Please what is the name of the big dish
Thanks for taking it apart and speaking to the quality of the unit. I installed it yesterday and I have taken my LRA down to 34 and my running amps just under 8 on my 3 ton Lennox.
Wonder what it would show with a low Z meter. Would be interesting to see how much of that is inductive or capacitively coupled and just a “phantom” voltage.
I fully agree with you about the real estate agents. And I don’t get the BS of them having their picture on their business card. I mean they are the only profession that does that. And you don’t pick up their card and say “damn I bet she can really show a house” 😂.
That’s a work of art.
Hey there! Would be cool to see this running MenuetOS or KolibriOS here in 2024 on this laptop if you still have it! Also a more full featured UNIX-like OS with NetBSD! ArchLinux32 would be cool but it is a bit heavier of an OS!
Nice attempt Bryan. Wondering if our PCBs can contribute to your daily work too, would like to help arrange if you are interested.(PCBWay Luz)
I hope you have a good fume extractor. 👍
Basically, it's a very basic, functional, utilitarian, industrial style Paternoster lift used to transport materials instead of passengers.
if its 220 AM means it was for the military but if i remember right they use 380 not 220
The fact that this video has so few views is a testament to why licensing is necessary. Great video !!!!
Hi Bryan, thanks for all the information. I have a question for you: This procedure could be used in a CM200 (EM200) series radio? I Have a LAM50RPC9AA1AN unit and want to collect information about modding it for amateur frequencies. My plan is to use it for M17 digital voice. Thanks!
Nice..like the labels..lol
I did upgrades in 2007 or so when the V.24 board went extinct in the middle of a countywide upgrade.... and they were impossible to find then! Nice work!
This is actually a better design, as it has a built in cross over port and no need to cut or replace the front cover for it to fit.
What spreadsheet were you referencing
That’s my tracking spreadsheet. It has a serial number of the unit and then VCO voltage/SINAD numbers across the tuning range. It lines up with the Quantar test codeplugs I’ve made available.
Excellent!
What, no Iridium?
Few hundred? More like 20usd, with shipping, for 4-layers.
Ive not found anything that cheap. That includes the stencil as well. I use PCBway.com for my boards and shipping from China 🇹🇼 is about 30 bux too. Im paying about 1.50 a board, so it’s a risk.
@@W9CR JLCpcb seems to be selling 4-layers for what 2-layers cost 5years ago. Cheap shipping for prototype quantities. But 1.5usd/board does sound normal.
@W9CR Will this work to convert a 1550ls+ from a 16 channel trunking radio into a 160 channel conventional radio?
Hello do you have one for sale covered to the 220 MHz band?
selam, daha önceden hiç kullanılmamış bir motorla telsiz aldım. telsizin programlanması için cps uygulamasını çalıştırdığım da uygun yazılım olmadığından dolayı telsizin frekanslarını giremedim. internette r03.16.00 firmware uygulamasi ile telsizi yeniden programladım. fakat şimdi ekranda " test 8 failed " hatası görünüyor. araştırdığımda codeplug uyumsuz olduğundan bahsediyor. ancak uygulama motorola'nın resmi uygulaması. şimdi telsiz ekrandaki yazı ile hiçbir şey yapmadan bekliyor. bunu düzeltmenin bir yolu var mı.

Your WiKi is an impressive resource for those of us really old guys out there. 😉 I certainly would never have the patience enough to deal with the cheapest group of tech oriented people out there --->> Hams ! LOL Seriously... Thanks !
Hams really are the dregs of society. This lawsuit shows that.
I'm running into an issue (mentioned by another commenter, albeit in a very nonconstructive way...) where I am making the changes using (legacy) Chirp with both the Jul 2021 and Mar 2017 Waris.py file, writing the radio (CDM1250) using a USB (serial adapter) programming cable, but when I read the radio back in to Chirp and CPS the frequency range has been reset. No errors from either Chirp or CDM1250. Not sure what could be wrong. This is on Windows 10 and the version of Chirp legacy as of Apr 2024
Geeze! They didn't even try to do it right! I hope you called them up and gave them a few words. That is just inexcusable.
Sadly, it’s typical if not expected

Just did an R0 to R2 ( well I cheated and only did the lower VCO 438-452 ). I like that the R0 receiver and exciter doesn't have any can to remove.
did you make C2054 16pf or 6.8pf?
Excellent just the information I was looking for. How length of the cables and type affects the notch. Thanks my friend. Kp4azh
Nice work. I can prob handle this! FYI at 10:25 your cell phone is bleeding into your audio recording…
Ugh
Nice and SAFE wiring no suicide cords
how did you blow the inverter
Starting the generator loaded (shown @ 10:06) may have had something to do with it. It's always good practice to start/shut off your generator unloaded to not only prevent damage to your sensitive electronics but also your generator.
That’s actually worse than I expected. And my expectations were low.
Honestly, I don't know what I expected. All these clubs seem the same.
Hams ruined ham radio..
Do you have the schematic or can tell me what pin number you take to ground for avoid the chip issue..or having the red battery...I'm sure the radio I have the old firmware in the radio.. I just got a Ht1550xls and need the software and the programing cable for it and want to be able to FPP for Ham use on the radio...Did u say Chirp can program the Radio??? Also do you sell or can you sell me a cable with a switch in it??? Thanks

How do you do this
I found your video. I have been looking for one of these on the used market. Is there a better site than ebay to find these? Thanks N8RLW
I wonder if it’s possible to change the Flash Storage for a larger one?.

Thanks for your video. Is the outside of the screen covered with glass or plastic?
plastic.
These are really handy. Only drawback is you can't carry a bunch of stuff with you.
Fully whored out, good man!
Very nice setup! Setup a VHF 6 frequency Narrowband compliant LTR system many moons ago. Used Telewave RX muticoupler with the output running through custom made crystal filters to eliminate a lot of the interference around the site. TX combiner was also from Telewave. This system worked great once it went onto a decent tower site. At the same location we had also built up a 220MHz LTR system, it was a fiasco from the start since the FCC only allowed 1 MHz difference between RX and TX. ACSB equipment from SEA Datamarine. Was not too happy about this since I am an Amature radio operator as well and the commission stole a portion of our spectrum for this junk. Must have been a planned failure to steal spectrum. From what I gather today some 20 plus years later, this section sits idle.
Do they still working after 11 months
So how do I change programing like frequencies scan? I have no idea how to change it seems to have me locked out. I'm a peace officer and would like to use it where I work.
