Hey Allen: Yeah, those 18650 batteries are pretty nice -- low esr as you point out, so great peak current capability. Modest capacities of only 3000 mAh or so, but being a single cell lipo it is

Hi Allen, Thank you for the info. Made a APRS tracker for model rockets using a TT3 chip. Going to put it in a small rocket with a single 250 mA lipo cell - it only has to last 30 minutes. A lot of

Eric, We use ( And include) a 3.7 Volt LiPo battery with our Micro-Fox 15s transmitter, which is essentially a TT3 at heart. Your TT3 has a linear 5 Volt regulator, so you will need to bypass it to

Hi All, The datasheet for the Microchip PIC16F628 (used on my Tinytrak 3) says it can run from 3.0 to 5.5 V. The PIC16F1827 (used on my Tinytrak 3+) is 1.8 to 5.5 V. Looking to run from a single Lipo

Thanks Joe, It's on my to view list. Regards, Doug VK2XLJ ________________________________ Sent: Saturday, 25 April 2020 11:33 PM To: [email protected] <[email protected]> Subject: Re:

If you change the status on your YouTube video to "not made for kids", it will allow comments and allow people to save it to a watch later list. YouTube really messed things up when they added that

Hi Rob, Thanks for the info, I will give it a go. Best regards.

Yes,The zip file with the previius version 0.68 has one.? I am pretty sure I I've used it. Byon could tell you what it wouldn't change, but I think it handles most of the settings.The change log

Hi All, Just finished building my TT4 and have installed the Alpha firmware, I am aware it can be set up by the command line interface , However I am curious as to wheather a Windows config utility

Good plan! Keep in mind that the internet side may have "a ton of traffic" that could be sent "over the air".You really want to limit that aspect.? ?? Knowing your repeater coverage and setting

Thanks guys, I do have internet at the site. I’ll take a look at APRX and maybe try to get it working here at home first and then just change it to my ID at the site and move it Curt

Yes, I've kept my eye on the products.? Thanks for the credit. My MTT4 is still setup with a bluetooth module connected at the Max232 chip.? The GPS I use is TTL also, so PORT B is just jumpered

I assume your repeater site has some kiond of internet connection to allow the data to connect to APRS-IS.In that case, I'd suggest APRX. Pretty straight forward setup and will do what you want.??

Rob, Just FYI, the MTT4 is no longer in production, and has been replaced by the MTT4BT and MTT4BT-40. We figured for the cost of an added BT module, it was not worth having four separate stock

I really just want to locate this at my repeater site which is currently just digipeating. By adding a Pi and some software I’m really just hoping to upload the data that I am receiving and

I got my shipment from Byonics yesterday which included of a TT3Plus kit.? I installed the included PIC into my old TT3? Version 1.01 and all is fine. Again, thanks for everyone's

Direwolf is an excellent application, but it is not "similar to APRSIS32". I don't see any mapping functionality in Direwolf.? I don't see how to connect Direwolf to the TT4 (the specific question
