Default APRS Made Easy/easier?

Ordered this cable, will receive tomorrow and hopeful it will work with my Kenwood TM-D710 and tablet running APRSDroid. I have also read it will work with my Baofeng.

Has anyone tried this yet?

I've used a cable like that with my Baofeng but with a moblinkd TNC connected by blue-tooth to the tablet. APRSdroid is a nice simple and useful UI and works just phenomenally with the moblinkd TNC and my Yeasu HT.
I think with your setup using the tablet for the entire TNC etc it will come down to the audio components on the tablet and how accurate and dynamic they are. You'll have to mess with levels to get good TX and RX on packet, I'm curious to see how well it works for you but expect it could be great with some tuning.

Whoa! awesome!

I used a standard audio cable for a while, then tried to make a homemade 2 way (didn't work) then ended up with a mobilinkd. It works well, but is bluetooth, and I feel like an unnecessary piece of the puzzle. I'm going to order one to try out.

What am I missing? You only need an audio cable with a couple of resistors to connect the phone to the radio. It shouldn't be complex. You can get the pre-made radio-side cables any number of places (I suggest Argent Data Systems) and the TRRS 4-pole connectors are like $3 from any electronics supplier.

for me it was rounding up the needed parts, then trying to shortcut using stuff I had on hand. I think that is why my home made cable failed.

The main reason I went with the moblinkd was because I wanted to use APRSdroid with a non-vox radio. With a VOX capable radio the phone-radio link cable should work.

I also want to ultimately hard mount the moblinkd with a mobile radio at which point the blue-tooth will be welcome a welcome addition and isolate me from wiggling trrs plug syndrome.

I may also be able to use my moblink'd cables in the direct android to radio scheme and see how it works but I'll have to check the pinout first.

In my APRS experimenting so far, my Yeasu FT1DR HT with built in APRS has proven far superior at both sending and receiving packets. It's really nice to not have to mess with any audio interconnects or level balancing for portable use, it just works. However the UI is junk compared to APRSdroid on a tablet so for my mobile set up I still prefer the moblink'd arrangement, I just need to replace the FT-50 with a full power mobile radio.

Did the cable work with your D710?

So what is the scoop on what to use with your radio in order to use APRS?

Is any tablet suitable? You do not need a tablet with cellular capabilities do you?

The wife and I started looking at upgrading phones and they are running a promo on a tablet - not sure if it would be useful? But I did think about APRS and wonder...
