Oh frabjous joy! Just got my notification as well. Shipping today, ordered 12/30/17. Waiting with 'bated breath.

Thank you everyone. I found the 7805 and it should be here in a few days. We'll see what happens then.

Assembler Language

W2CTX
 

In my former occupation we used to dump the assembler language listing in
order to see the code generated.  We did this either to minimize code space
or make it faster.

Is there a way to list the assembler code via arduino ?

uBITX in compact Jameco case #ubitx

John Pieper
 

I finally finished the packaging of my uBITX. I had it on a breadboard for the first month of operation (I got one of the first batch).
The case is the Jameco Case Metal 6.3" x 7.75" x 2.5". It is a very close fit to the board, but I wanted a compact, streamlined
look for this one.

I had already planned to mount the IRF510s to the rear panel with insulating kits for heat sinking, but it actually still lacked
about 1/8 inch for having the LCD completely inside. I made it fit by removing the plastic standoff on the right-angle header on the
Raduino board with some hobby knife work, then heating the pins and carefully pushing them farther into the board until the board
was right up against the header on the main board when plugged in. That did it and I could then just cut a window for the display.
I didn't use any mounting hardware for the LCD, because none was needed! It's not going anywhere. This contributes to the clean
look of the front panel that I wanted.

The four jacks under the display are (l to r) Key/Paddle, Phones, Mic, and Data. The last is combined audio in and audio out
for connection to a sound card interface. Together with CAT to the USB port on the rear panel, only two cables are
needed to operate digital modes.

There is still 1-5/8 inches of space available on the right side of the case for a daughterboard that will hold AGC, a SCAF
filter, and forward/reflected power bridge. I'm working on the board design now. I plan to control AGC on/off and filter in/out
from the menu by use of an analog switch IC on the board. The SCAF center frequency and bandwidth controls will go
above the volume control.

By the way, the 7.75" "length" dimension really is left to right width of the front panel. I actually had to check with Jameco
because the datasheet linked to on the product page has the dimensions reversed on the drawing. I just checked and it
seems they have still not fixed it as they promised.

Mike,

I think you are right about that...I looked at the schematics and they support your ideas.

I shot from the hip on that one.

Hi Lenny,

There is another possibility- the +5 power line may be shorted to ground.

With the power supply to the rig disconnected, you could try measuring the resistance from the center leg of the 7805 to the lower leg of the 7805.

The resistance should be probably greater than 100 ohms. If it is substantially less, there is a short to ground on the +5 line.

That would be worth doing before you replace the 7805.

Re: Completed radio and it is not working

Don't know where he is?

Radio Shacks closed in my area. 

Tayda is about 1 week,  Mouser about 5 days.

I have used Mouser for decades, really like them.

I got a 100  7805s a year ago for about $23 at Mouser.  They work down to a real low voltage too (LDO).

It's open  so I guess that confirms the 7805 is bad.

smoke

richard stafford
 

GM all:
My bitx40 initially functioned well with all CW modifications except for initial problems with relay activating with each key closure, despite speed. Tx-Rx initially to pin 15 along with cw carrier, as per text. Changed connections according to photos (Tx-Rx D7 at pin 16, carrier D6 at pin 15 and side-tone to D5 pin 14). All seemed fine, then smoke. No visible damage. Now transmit output is down to about 1 watt, receive audio present but very soft despite full AF gain, and side tone volume on transmit is initially at the usual volume but fades to the same low receive volume after a couple of seconds. Power at the antenna stays at about a watt.
Went through Farhan’s trouble shooting; no audible change when touching antenna input. Toroids look ok.
Great rig, and despite these issues I wouldn’t trade it for anything else, except perhaps my HT 37 and Drake 2B.
Thanks in advance for your help. Great site as well, by the way.

As a temporary fix, the Radino could be powered via the USB port until you get the 7805 in.

You can put the 7805 on the other side of the PCB, flat and not hanging out. Also put a diode, 47 ohm 1W resistor to input of the 7805. Then add a capacitor on input to ground.  Like 100uF/25V.
This is what a lot of folks do.  See attached schematic.
