An additional comment is that whe using the Byonics cable, it powers the MT-8k all the time.The configuration applciation requires a power cycle to get to the bootloader. If you unplug the USB cable

What kind of a USB-to-Serial cable do you have, a Byonics programming cable or a standard USB-to-serial cable? The Byonics cable will power the MT-8000FA during programming to avoid problems with the

That's a curious statement since you just joined the Group this morning. Yes it's monitored and yes, it's active. I'm sure you will have some member provided input quickly. And, please, always sign

I'm not sure if anyone still monitors this group but I have a Tiny Trak that is not being recognized by the software.? I have isolated every usb port I have and labeled them accordingly.? This is

Brian, I received your MTT4BT today. It appears that the corruption of the TT4 ATMEGA controller stemmed from the 2.5mm PORTA jack getting a bit bent and having intermittent contact. The programming

It may be due to loss of precision in the arithmetic used by Byon and not round off. It could be both. Without seeing the code employed in converting temp input to ascii for embedding in the aprs

So it appears the issue was most likely rounding.? Now that the temperature is "significantly below 0" it is displaying as below zero. Glad it is working! Robert Giuliano KB8RCO

Robert Today morning the temperature reaches negative temperature in Celcius , so my question was answered; 20/07/2021 06:18:02-03:00: *PY5LF-13*>APTT4,PP5CRE-15,WIDE1*,WIDE2-1,qAR,PP5APR-10:WX

Brian, Well, we do our best not to send out units that are bad right out of production :) I look forward to getting your unit and I will make sure it is ship-shape and Bristol fashion. 73, Allen

Allen, Very much appreciate your offer. I'll get it out to you next week! The odds that the issue is my fault is much higher, than it being a lemon. I did my due diligence at each step to prevent

The amplifier is the black widget mounted to the board with screws, above the metal can. ( The RF module)? Other than a really awful short circuit of some kind, it's unlikely the 2.5mm serial port

Allen, Thanks. I have been using the V3 "Hershey Kiss" antenna that Byonics sells: Nagoya UT-108UV. https://www.byonics.com/antennas The antenna is placed on a piece of sheet metal for ground plane.

If D6 is blown out, you won't have any power to the amplifier circuit, including the T/R relay. The diode is rated for a surge rating of 9 Amperes. You can check the circuit by measuring the DC input

D6 is the main input to the RF amplifier. Robert Giuliano KB8RCO

* Yes, second interface to the computer with the 2.5mm jack. Yes, Jumpers set j4,j5 top jumpered. MiniDin- * Cable side- Ground at 5 but not 6. * Board side- The bottom two have continuity (yellow

When you say second one down, are you referring to the page, or the second computer interface with 2.5mm jack? I think you are using the 2.5mm Jack, which is the same as the BT module.? Are you

It is the cable from Byonics, second one down: https://www.byonics.com/cables Has the MiniDIN and PortB as you described. PortA uses the 2.5mm jack, PortB is the MiniDin split to DB-9 and Power

What is a USB 2.5 cable?? Are you referring to the 2.5mm jack for PortA? Sounds like a wiring issue - possibly ground. I am not familiar with the MTT4BT.? I have the MTT4B that I added my own
