I knew it! The frame, the neg ,the pos. Are the power side Thank you!

Yes but you say it flows to the ground ,current is pulled in by the pos flows neg to pos

@@artyfuffkin7805 Electron flow and current flow are in the opposite directions. My votech teacher was brought up on current flow, I even had current flow text books which were bizarre. I probably don't see electricity the same way you do. Do you post videos?

@dc95811 OK draw the primary ign esp the coil then explain it working going pos to neg ...this is what manuf. Training does Me 2 yrs auto votec 30 yrs nissan mitsu ,Volvo, jeep eagle 5 elect train classes ASE MASTER 12 YRS

@@artyfuffkin7805 No videos then? No worries. Just do a google search of "electron flow vs current flow" and you may find out why the arrow symbols on diodes and transistors point the way they do. With all due respect.

Just audio, the only id will be of the transmit portable. You can do analog to analog, or mix mode by the channels you select. The logic involved in passing ids is why P25 repeaters are so expensive. This is definitely a poor man's version. P25 on the receive makes it almost as good as a full priced repeater because the audio is perfect going into the transmitter, not adding noise.

My pleasure I am glad you enjoy them.

It doesn't need a usb driver, it uses rs-232 thru the computer's serial port. If you don't have a true 9 pin serial port, which a lot of computers don't have anymore, and you are using a usb/serial port adpater, you will need a driver for that adapter, but not specific to using the garmin.

They slightly tweek the standard voip codecs like g711 ulaw so it sounds garbled. They were smart in some ways making sure their stuff was proprietary. I had great plans too if I could crack that code. Lol.

Both notches are used, 1 blocks the transmit freq and the other blocks the receive from going into the dummy load. The duplexer is tuned the same as a normal application. It works perfectly as described if you transmit high (159Mhz) and receive low (151Mhz). I found that if I reversed the tx and rx frequencies I would get a very large desense that would really limit the coverage. Your timing is amazing on the comment because I did find the cause and a solution to that problem. I learned that most all of the times I blamed desense on a receiver having its frontend overloaded, it was more likely a near-field on-frequency rf product that was desensing it. I just made this video showing how it does it.

That’s not how that works with the dummy lord. You are basically only using one side of the notch. The reason for the transmit side going through the duplexer is so that side notch can be set to notch out any spurious signals coming out of the transmitter that would be on the receiver frequency. The amount of loss you are going to see by running the transmitter thought the duplexer is really not much. Plus by using using the same antenna for both you won’t end up with an alligator or elephant repeater. And I say this from having a mobile repeater in my 4Runner and having a uniform antenna pattern is really the goal and makes you no always wonder about TX or RX issues.

I know exactly what you are talking about. A reverse bridge. I had the same idea for rs-232. The answer is no. I will put it simply, those devices can only communicate on the ethernet with other devices like itself, that does rs485 stuff. It would have nothing to say to any of your other tcp/ip devices and would ignore them.

@@dc95811 Thanks for responding to my inquiry. Ill just give you the whole story. im trying to connect 2 ham repeaters together over a 900mhz data radio link that is rs485 only. the ham gear is tcp/ip. My prospective thought is that at each location id have a eth to rs485 converter. ham repeater with eth card connected to converter > rs485 to data radio > data gets sent over the air to the other 485 data radio > converter back to eth then to the ham repeater.

@@wedgeantilles1678 dialup modems using rs232 to rs485 converters. PC's at both ends, bridged ethernet port at remote end to a little switch, giving those devices access to the dialup modem, and a way back home to the LAN.

@@dc95811Thats brilliant! Im gonna try that. Its gonna be a complex hodge podge but thats what ham is all about and itll sure fit the budget.

I believe that is referring to the packet transport layers.

Yes. Codan did a write up on it called TN857. Here is a link to the pdf. cdn.codancomms.com/general-downloads/Products/Tech-Notes/Codan-TN857-2-CI-IP-ADAPTER-224-Tech-Note.pdf

Oh yes, every single connection at all times it is energized has lethal voltage present. More like ground is fake, because we happen to get a neutral connection to it giving it a 120V reference. If in doubt do not touch it.

It is just like RS-232 but can be ran down a lot longer pair of wires because the voltages are not referenced to ground but to each other making it more noise resistant.

2 videos back I used them to remote a 2way radio head at 115,200 baud and they worked great the first time I hooked them up. The company didn't make it easy to find, but I found the pdf write up to put them in bridge mode. Idk how they make a profit.

Above thanks!

@@dc95811 Keep up the content. You did a good job on this one.

This is a much better way of doing this. And please watch muted. This is for info not entertainment. ruclips.net/video/adxZhU7-qWM/видео.html

I apologize, it has been almost 3 years since I have used a T-Berd. It has all faded, I'm back in the 2way world these days. When I did do testing, we physically put a separate T-Berd at the distant end.

​@@dc95811 you can definitely put a softloop at the other end as far as the circuit is an open pipe and there is no equipment in between the network far end and near end then the tester will definitely identify the remote loop

Thank you I hope they help. Not a great deal of commercial LMR content out there.

That is a windows gem from the past I have hung on to and it isn't available. A new and improved version called Real Term is at sourceforge.net/projects/realterm/

Thanks. That was narrowband 2.5khz. Will do a P25 version soon.

Thank you. This has been my favorite video so far. It is amazing at how complicated it can be to create long distance virtual wires.

If you get a KAA0660 remote head kit, KAA0636 remote cable and a KAA0661 cover you should be set. Suggest monitoring EBAY. $$ :( BK just covers up the dash mount head with a cover, yes, I kid you not. They both work btw. Then the remote plugs into the back via control cable. No head/interface board swap like a Motorola. Make sure the firmware is the same version between head and radio.

Thank you very much! Now I have my shopping list and a good project to work on!

I would want to do a double swap with a known good phone. Does the "bad" phone still not work when plugged in to a jack that usually works? And does the phone that is known to work show the same "bottom row only" effect when plugged into the original jack? My guess from those symptoms is that it's just a bad phone.

The transformer should not effect the phase. I cut my oscilloscope probe and installed a 10M ohm resistor in series, so it would be ultrasafe. Scope is already grounded so all you need is the single probe.

Thank you, that made my day!

My employer got it with the purchase of the repeaters we use. I think any Midland dealer could hook you up.

I found the program, now I need to find the programming cable

@ededison9404 where did you find a copy of the software

@@TheArcadeguy I had to sign up , it was easy peesy

It is impossible to directly convert that without being able to control the sentences put out by the GPS, and the rate at which the GPS outputs the sentences. Too many sentences means too much data without enough time to get it out, and the buffer gets involved and then quickly overfills. So you would have to reprogram the GPS. But here is the good news. The GPS module can be reprogrammed for 4800 baud. If you look on page 36 of the mega spec sheet on the NEO-M8 at the link below, you will see 4800 is a selectable option. I know you have to use UBlox U-Center to reprogram the modules. I haven't done it myself, I'm a Garmin guy. But there is lots of videos on using it. content.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_UBX-13003221.pdf

@@dc95811 Thanks my friend For that

There are a lot of things that have to be clarified. 1. First define what you mean by wifi "turns off". That could mean many different things. Is it disconnecting but staying enabled? Is it disabled? Or does it just not work? 2. If you unplug the ethernet cable, does the wifi automatically start working again? If not, what exactly do you have to do to get it working on wifi again? 3. The NCSI, the network connectivity status indicator, will always take ethernet control as far as what is seen in your task tray at the bottom right of your screen, that is because it wasn't meant to show 2 at the same time. But that doesn't mean wifi isn't connected at the same time and is working. I could just go on and on. But I think in answering these questions you would find the answer to what is happening. Think of it from the app's side, it wants this data and it has 2 choices from where to get it from, which does it choose. If it thinks it can only get that data from just 1 side it will always pick that side to get it. Task manager performance screen is the only real way to easily see what it is chosing in real time.

Thanks! It all started with brainstorming and testing on how to get telex roip voice traffic across the internet. Forget roip, I'll let Bill G carry the audio all the way there. haha
