Re: Calibration - my approach
#ubitx
ok - no problem. One step at a time, right?? Quoting from:?? /g/BITX20/message/47482" Another member of the group gave me this advice.Tune to 7074 using LSB. You should hear nothing. Then change to USB andyou should hear all kinds of psk and other digital modes.If you hear these signals in LSB then your BFO frequency is notcorrect. My BFO was way off after I first tried to calibrate it. I then startedover with mine at 996.4 and ended up at 996.7. If yours is a long wayoff from that then I'll bet you hear psk at 7074 when in LSB."For my interpretation of the above, I Step 0: Confirm that the BFO is set to 11997.00 (via the radio menu which is accessible after you enable "Setup On" ) Step 1: Set frequency to 7074 Step 2: Set mode to USB? Step 3: Confirm that there is audible digital activity Step 4: Set mode to LSB Step 5:? Return to the "Set the BFO" menu (at this time in this menu, you can not adjust mode or frequency)? Step 6: while listening to 7074 on LSB, adjust the BFO for the lowest audible level of the digital signals.? (in my case, the default 11997.00 was good. I don't expect that you'll need to adjust this much at all). Press the PTT button to write to uBITX memory Step 7: Set mode to USB - ensure that you can still hear the digital signals well.? Note that I did have a very strong, lower audio frequency digital signal that still got through on LSB,? but all of the others all but disappeared with BFO adjustment.? ? Good luck!? -- Dave Beal AE6RQ

Re: Nano Capability with 2.8" TFT Displays
I updated my blog with a link to my existing sketch utilizing the TFT display. As I am not interested in CW, I have left as much as possible with out any changes. When I get some other projects finished I will look at some of the updated code to see what I want to modify or add. Only hardware change is a small board with the voltage divider resistors that the TFT display plugs into. From there a cable goes to the existing display connector on the Raduino board.

Re: ND6T AGC implementation for uBIT-X
I will certainly purchase a ready made PCB for this design.? I did ND6T's small PCB as he described, and wasn't happy with the result.? My work not his.? I did purchase a small lot of 2N7002 SMDs; more than I can ever use, so I would be willing to make this my contribution for getting this PCB produced.

Re: VK2AUJ's ?BITX project
That math may look silly.
We found that the silicon was just a couple degrees C hotter than the tab.
But the math becomes important on something like the IRF510.
Many Bitx40's are getting around 20 Watts out by raising the PA-PWR voltage to 24 volts.
Assuming 50% efficiency, that's another 20 Watts going up as heat in the single IRF510.
The IRF510 has nearly the same numbers as the LM7805:? 150 C max,? junction to case of 3.5 C per Watt.
With 20 Watts dissipation, the die (junction) is? 20*3.5 = 70 C hotter than the tab o the TO220 case.
And the tab is hotter than the heatsink, perhaps by quite a bit if the tab is electrically insulated.
So figure the die might be up to 100 C hotter than the heatsink.
The IRF510 heatsink should never exceed 50 C to keep the die below 150 C.

I measure the current from my 12v supply into the LM7805 on the Raduino at 60 ma.
So the LM7805 is dissipating (12v - 5v) * 0.060amps = 0.420 Watts
And we can calculate the junction temperature to be 4 * 0.420 = 1.68? degrees C higher than the TO220 tab.
The junction temperature is just a couple degrees C above that of the metal tab you see on the outside of the package.
