Re: Problems with Arduino Nano: has anyone the program for BiTX 40?
There are two orange wires in the supplied wiring harnesses that connect to the Raduino.
One of the orange wires goes to pin 15 of the connector labeled "OSCILLATORS" in the schematic,
this wire should be connected to +12v as shown in the wireup diagram.
The other orange wire goes to pin 5 of the connector labeled "CONTROLS" in the schematic,
this wire goes directly into the A3 pin of the Mega328p on the Arduino Nano processor.
The schematic is here: ?http://www.hfsigs.com/bitx40v3_circuit.html
The wireup instructions are here: ?http://www.hfsigs.com/bitx40v3_wireup.html
Sometimes shorting a Mega328p pin to 12v (such as the A3 pin) only blows the IO cell for that pin,
but since nothing works at all anymore it seems you have blown the processor and it must be replaced.
You might try buying a new Arduino Nano processor board off the web (perhaps $4 USD),
but installing that on the Raduino board will require removing the 30 soldered pins of the blown Nano first.
You might buy a new Arduino Nano plus one of the Si5351 breakout boards and a 2x16 display, create your own Raduino.
Neither of these will be trivial to do if you are not experienced with this sort of thing.
Perhaps I am wrong and someone will have a suggestion for an easy fix.
But I think your easiest solution is to buy a new Raduino from HFSigs.

I need the program in Arduino Nano, so I can substitute it (Arduino with a new one), in this way my BITX 40 can works again because it works really well, is a greate trasceiver and its very useful for portable use.

Re: A little ardunio help
Well, I'll bet that's why the compiler can't find it. Did you download it when you downloaded Rel106? You can download it from the users group File thread, or just use the one I've attached here.

Re: A little ardunio help
You can always give full path to the files in the #include line.
This makes the code custom and a bit less portable but experienced coders can
probably handle that.?

Okay a quick peek inside the B40SoftwareRe10106 folder shows nothing but that file. Nothing else.

Re: A little ardunio help
I am on the road so I can't verify this but I think you actually must have the compiler connected to some version of the arduino for the code to compile. I think I ran into the same issue; but, there may be a workaround.

My BITX-40 is built in a wooden and clear acrylic case so all of my build, can be seen in or out.? Keeping in line with this type of construction, I decided to make a hand mic out of wood also, which is nearly complete as I write this.? Then with a desk mic in mind, with push to talk, and a hold button to follow?built out of?wood, I was thinking about a design.? At a ham swap meet last week, I found just what I am going to use for my wood design.? So for $2.00, I now have a pattern and probably a mic that works.? It is a rather small, Radio Shack, Realistic, dynamic, catalog no. 21-1176?that is?less than 8 inches tall.? It is?all plastic except a metal base for weight.? It comes apart easily with screws, so there is no breaking plastic tabs off or anything to change the mic element to the electret that came with the BITX kit.? Attached is a photo of the mic.? 73, Karl, KO8S

The BitX40 with no mods is ready to be powered...except for the microphone. Today I worked on the PTT bar. A parallel pair of switches should take care of me pushing on one end of the bar or the other without any ill effects. I think I had rather work on metal than pvc. I'll try to get the mic operational, do a wiring check, then power on in the next few days.

Hi Jonathan,
thanks for your follow-up. I am sorry you are still having roblems with the pop.
I have just discovered I marked the wrong pin on my circuit diagram, I reported pin8 as the power input in place of pin 6. I am attaching the updated schematic.
Pin 1 should go to ground and not pin 8 to +12V via the 2N3904 collector. I hope the LM386 is still OK as I do not understand why it should not return from mute.
Please let me know. Thanks and 73

I just tested my r141 on all 3 bitx radios I have all are 10ohm but I will change them for 1/2watt resisters I up graded the pa heatsink today as seen on my photo I not planing on running more than 13v from battery's when portable?
On 18 Aug 2017 02:17, "Jerry Gaffke via Groups.Io" <jgaffke= [email protected]> wrote: A 1206 surface mount resistor like that is typically rated for 1/4 watt.? Might seem high, as a 1/4 watt axial lead resistor is considerably larger.? But the 1206 can can better dump heat into the board.? I'd replace R141 with a 1/2 watt part, either surface mount or axial lead. ? If surface mount, it will need good thermal contact with the board to really dissipate 1/2 watt.

I find the easiest way to remove two terminal surface mount R's and C's is to use two soldering irons.? A Sot23 package like all those npn's can be removed by heating and prying up the pins with an xacto knife one at a time.? More pins than that and I go to a hot air gun, I've got a 250 watt Weller 6966C, built for use around electronics.? You can probably get by with an "Embossing Heat Gun" at under $20 and do the same thing.? I shield nearby parts with tinfoil before going after one with hot air.? I've heard that Chip Quik works well, it effectively replaces the solder holding down a part with solder that has a much lower melting point so it is easy to pull off at moderate heat. ?

I took a close look at R141 and it did look burnt. I measured about 60 ohms across it, but it was fluctuating. I don't yet have any SMD resistors, so I replaced it with an axial resistor and got it going again.
It was good timing that my (el cheapo) hot air soldering station just showed up. My very first use of it was to remove R141. I put some Kapton tape each side of it to try and prevent disturbing adjacent components. R141 came off in the two pieces. I went back to a regular soldering iron and some wick and soaked up all the solder on the pads. I then shortened and bent the leads on a 1/4W 10 ohm resistor to get them to fit on the pads. Does anyone know how many watts the original R141 was rated for?

Thanks for reply all.
I have the equivalent drive level resistor. ?The procedure call for pre setting the IRF 510s to 50 ma each, and then adjusting the drive level pot until the increase in voltage slows down. ?This should occur at about 12 watts. ? Then back down about a half watts. ?Originally I was able to see about 15 watts if I kept going
but now that point seems to have dropped to about 10 watts, so I back down about 1/2 watt from there. (measured on a scope and then using formula)
I guess I have to start measuring voltages on all the transistors.

Here is my solution to the PTT Mute and the addition of a Linear
Amp keying circuit.
I just dead bugged the H11AV1 Opto coupler on top of the LM386
to make the connections as short as possible.
Any Opto coupler with an NPN transistor should work, I just had
a slug of these GE H11Av1’s in my junk box.
Good Luck…see you on 40. KC5RT Fred.

This is the version I used. I see when I have another look it is version3
anyway it seems to work for me. circuit as below.
I added at the junction of the 1k resistor and the emiter of the 2N3906 a
22mf Tantalm and a 103 ceramic capacitor and feed the 12v via a 100ohm
resistor.

QRP Labs 5W CW transceiver kit
None BiTX,
but hope it is of interest to others if it hasn’t been mentioned elsewhere.
QRP Labs are in the process of kitting up a new Mono Band 5W CW Kit for the HAM Bands.
A great feature for those with minimal test gear or field use is:- B.I.T.E.
Often found on commercial / Military equipment.

For alignment of the RF & AF Stages.

No commercial connection etc, etc.
Other than a happy, past customer.

p.s. no extra bits really needed for my unit, transistors just what was to hand (scrapped from a PC PSU). If Ted has put in extra caps it would likely be to keep it muting a few milliseconds after PTT release - right, Ted?
