Hi all,
?
I have an unopened/unmodified BiTX-40 for sale, purchased on January 25, 2017. ?I'm just not getting enough time for projects - as is obvious between the purchase date and now! - so it's better to get it into other hands. ?It even has the original India Post cardboard box!
? Price = $55 including shipping?by Paypal. ?I will ship by priority mail to the US address you provide. Shipment outside US would need to be discussed. ?Please contact me at W1PJE at arrl.net for the Paypal address and other details.
73,

Allard I use this service DXRobot. I get audio alerts on a simplex node I use that gives me propagation alerts. I get alerts everyday when 6m is open

So we already have a filter to cut audio outside the 700-2800 range?? I was building a SSB-Mite from 4 State QRP Group.? I searched the messages for it and did not find anything.??

Re: Teensy I2c on wire2 (SDA2/SCL2)
#ubitx
I don't think the issue is the bus voltage. The issue is getting the SDA2 and SCL2 pins to work instead of SDA1 and SCL1. The Wire library seems to only handle SDA and SCL, not any of the other SDA/SCL combinations available on the Teensy. tim ab0wr On Thu, 31 May 2018 23:31:32 -0500 "AA9GG" <paul.aa9gg@...> wrote: Haven't tried it, but remember that the si part is running at 3v and

Wouldn't be easier to set fixed UTC hours instead of local time? Local Time just too dispersive in my opinion.

Re: The new uBITX boards are here
Bob,
The "old" board works well.? You will likely be happy with its performance.? There are some mods and kits for mods available to fix the few minor issues that may or may not bother you.? If you read up on ZL1AXG, Mike's blog, you will find useful information on those things, but it is recommended to first assemble your radio and try it as-is.? Have fun and learn a lot!??

Does anybody know, in case one updates the firmware, whether the bfo settings are left unchanged or not?

Maybe a simple solution with a NE567 as a PLL FM demodulator / synchronus AM detector will be ok in order to keep the cost and the complexity of the circuits down.

uBITX -Regarding the PA transistor heatsinks.
?
I can see the insulation argument to why these are installed hanging on to the IRF510s but this puts a large mechanical load on the transistor legs and increases the risks of damage especially if one tried to use the uBITX as a portable, even as a SOTA rig.
?
One could fit a larger heatsink that was fixed to the chassis/casing or PCB and one would then have to add rectangular insulating washers between the transistors and the heatsink.
These changes would increase the parallel drain(s) capacitance to ground
?
What sort of negative results should/could one expect from these measures?
?And could one fix'em?
?
I envisage these positive results:-
-?????? better mechanical strength
-?????? easier to provide controlled cooling of the heatsink.
-?????? a slight increase of weight
?
Someone has suggested use of? very beefy 6400BG heatsink, this has two solderable pins installed in the one end of the profile. However the uBITX board has no room for these.
