What's the difference between the APRS-K1 and APRS-K2? Would you know if one of these cables would work with a Baofeng DM-1801 DRM radio and a Android cell phone running ZELLO ?
I just bought one of these cables and I am excited to try it out with my BaoFeng UV-82. I am going to use a RaspberryPI running DireWolf and a custom APRS client application that I built. I had been wondering how I was going to connect the radio to the PI and be able to properly trigger the PTT. I had tried using the one that came with my MobilinkD but it seems to only work with the MobilinkD. I hope this cable does the trick. 73
Keep in mind that the 3.55 jack on the pi is audio out only, and to receive you would need a usb sound card with an input as well, and an audio cable splitter for input and output. This is probably the problem you faced with the mobilinkd, as it is the same cable.
I'm using the BTECH APRS-K2 APRS Cable with APRSDroid and the UV-5R. I've tried recommended settings for Vox, Squelch and the Frame Sync but I can hear that the first part of the APRS packet is being clipped so it is not successful unless I physically hold down the PTT switch on the UV-5R. Any suggestions? I've monitored the packet transmission with another radio and it's very obvious. I can't seem to get past this clipping issue for some reason.
What are your settings on direwolf where you use a audio aux cord for Rx to the raspberry pi sound interface. Mine wont work that way.....I'd like to use the aprs cable with my rpi4 w direwolf...thanks Trevor KJ7MLK
If you can and are familiar with electronics, can you please try to open your cable and draw a diagram of the components, and how they are wired. I made myself two reduction cables witch reduces the volts to mic levels, on cable for the pc or phone to radio, and one for radio to pc or phone. But the problem is the baofengs are built that when the to grounds of the mic and speaker are shorted or connected it starts transmitting. The pc's mic and headphone outs are obviously grounded to the same ground. That's why I'm asking for a solution. Any answer will be appreciated.
I had worked with CORs but not for this APRS cable. The Mic (-) gnd is connected to SPKR (-) gnd. PTT should be left unconnected if use VOX, which is this case. Miklor diagram had MIC gnd showed shorted to PTT, but actually not in headsets. You can confirm it yourself, in your headset.
Check out github.com/johnboiles/BaofengUV5R-TRRS . This repository has plans for a small pcb and what to populate it with to make your own cable if you want to.
Must I buy the cable you use? I have a 2.5mm aux converter, a 3.5mm audio and microphone connector, and two 30cm cables with 3.5mm male aux on both ends, are these enough?
@ModernHam Hello! When you say "overdrive" do you mean the volume intensity of the sound? If so, I haven't had any problems. extra: The microphone and sound mixing equipment caused it to be stuck at tx for some unknown reason. I think I might want to buy this aprs device, which is kinda expensive for me. Frankly, I'm not sure. 😅 And thanks for replying man! 73 de TA3WOA 🫡
Do you think this would work with a laptop and FLDIGI for EMCOMM messages via HT? Some of the surrounding counties use the FM repeaters for this. Thanks in advance!
I'm using a LUITON LT-188H ht ( 10 watt supposedly) in conjunction with this cable. Also using a older cell phone (not activated) with aprs droid. Works perfectly. I wish I could say the same for the MobilinkD ( which I could never get to work at all.)
Enjoyed your video. I just started to get interested in APRS. I also want to learn Winlink for sending emails over the radio. I just learned that there is a Android app for Winlink called WoAD. I dont know how to use it yet. But I will need to get the proper cable first.
So, this setup basically works as an igate too, right? I live in an APRS dead zone, so I'd love to have this setup at my house to receive while I'm out and about.
While you can have it upload your position via internet, it will not transfer rf packets and upload them via the Internet. A raspberry pi combined with the baofeng or an rtlsdr will however make a great igate.
@@AlexanderSpear I've personally used the raspberry pi b2 as an igate, but it does require a bit of computer know how to get it setup and working. The RtlSdr makes an excellent igate because igates are receive only. If you're looking to transmit as well, you would be making a digipeater. The RtlSdr combined with any radio that can transmit with an audio interface is an excellent combo for a digipeater. This allows less packet because the radio loosing packets switching between send and receive on it's own.

What is the difference between the K1 and K2 cables?
In Settings / Connection / Audio Output, which one should be selected? I have Voice Call/Ringtone/Music/Alarm options.
Thanks. :)

Can this be used for ip radio to analog Zello audio interface?

Hi,
Can I use that cable to connect my Yaesu FT3DR to the APRSdroid APP? Thank you. Eric
Can you still send and receive voice transmissions with this setup?
Thats a negative
How do you determine the APRS frequencies? Are they listed in Repeater Book?
It's just know that the aprs freq is 144.390 in North america. There's not really multiple.
ModernHam check APRs.org. Different free for each continent.
How can I know if it is sending beacons through RF and not internet?

@@Gülümseyen_Gezgin As long as you can wire it up right, that should be fine. You will just need to take care not to overdrive the audio.

I hearing carrier at the end my APRS data transmission what do think it is?
My Samsung does not have a jack like that. They did away with them. It only has a usb c, so how would I connect to the phone?
USB C to 3.5 MM TRRS adapter.
Do you think this would work with a laptop and FLDIGI for EMCOMM messages via HT? Some of the surrounding counties use the FM repeaters for this.

can be used in zello?
So, what else can you do with this cable and a Baofeng besides t/r APRS?
Any type of audio link. You could use it to transmit drmf tones to a computer and have it respond with specific information etc.
Good overview. Just setup mine this evening. DE EI5HZB.
So, this setup basically works as an igate too, right? I live in an APRS dead zone, so I'd love to have this setup at my house to receive while I'm out and about.

@@ModernHam can you recommend a raspberry pi? I have no experience with them. Also, I have a rtlsdr, but it wouldn't tx because it can't do that.

Can you program CHIRP for APRS, if so what are the field parameters. Thank you Ernest Bazzinotti KC1LKB
Did you find an answer?
What does the cable smell like?
Chinese Factory
@@ModernHam haha
Thanks for the video.
Good very beautiful
I thought the cable just had a ferrite bead.
I had to apply for a password. Did you have to do that too?
Yeah. Anytime you want to upload information to aprs.fi, you are required to have a passcode.
ModernHam messages/images don’t though right? Or when/why would I need to upload to aprs.fi?
did you try to RECEIVE aprs with baofeng? tell us the truth!
can i use zello
Yes. I don't have the cable but it's suppose to work. I made my own cable. Still what to connect it with Zello.
