Re: I need a V3 or V4 uBitx board.

 

Jerry,

Sorry for the poor picture, that is the correct part number though. These relays have the exact same specifications and pin out as the original one's Farhan used. There is nothing really special about them, you can buy them under a lot of different part numbers and I haven't found one to be any better than another. The yellow color is probably the worst thing about them, but they have been very reliable otherwise. I have also seen these same relays used in commercial equipment I have repaired.

Re: Ubitx schematic #ubitx

Hi, Art.
The Raduino board provides a T/R signal that operates a relay (bottom-left on the schematic). This relay switches power to the RX or TX circuits.? I suggest you use a highlighter to mark TX and RX at the relay with different colors and then peruse the circuit and likewise highlight the TX and RX connections throughout.? The transmit and receive sections then become clearer and you can trace them as you wish.? You also will see TXA, TXB, and TXC.? These signals from the Raduino control the three relays that switch in or out the filters shown in the lower-right section of the schematic diagram.? I hope this info helps.

Re: Keypad for Raduino...?

Robert McClements
 

Arv,

The?TTP229?capacitive??keyboard has two pins labelled SCL and SDO but unfortunately they are not I2C.

The way that they work is SCL is clocked frequently up to 16 times and during each clock cycle SDO is
checked. If a key is pressed SDO will return a Low, the count stops and the clock count equates to
the key number. Hope that makes sense, not easy to put into words.

So this device will require the use of two digital pins.


Regards,

Bob GM4CID

Sample code below :-

?// Routine to read if a key is pressed and return its value
byte Read_Keypad(void)
{
? ?byte Count;
? ?byte? Key_State = 0;
? ?for(Count = 1; Count <= 16; Count++) // Pulse the clock pin up to 16 times and read the state of the data pin on each pulse
? ?{
? ? ? digitalWrite(Clock_PIN, LOW);
? ? ? if? (! digitalRead (Data_PIN)) // data pin low store the current key number
? ? ? ? ?Key_State = Count;
? ? ? digitalWrite(Clock_PIN, HIGH);
? ?}
? ?return Key_State;
}?
Re: Keypad for Raduino...?

 

Could work.
Though scanning a keypad with i2c will consume a lot more processor time
than just reading some IO pins.

Re: I need a V3 or V4 uBitx board.

 

The Bitx40 and uBitx use relays with a 12v coil,?
there are some very similar relays out there with 5v coils that would not be suitable.

The relay that hfsignals has been using is harder to find, looks like Amazon did sell them in the past:
? ??

Here's an old thread on relays:
? ??/g/BITX20/topic/bitx40_kit/5069237?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,5069237
I doubt the $0.50 relays being used have any special tricks, so no diodes, no permanent magnets embedded,
these are not latching relays.? Solid state relays are not suitable, they are usually designed for use with 60Hz AC.

Here's the pinout used by HFSignals:? /g/BITX20/message/47000
Though some manufacturers number their pins differently, flipping the relay 180 degrees.

Another interesting possibility is using an Android phone or tablet as a touch screen controller
communicating bluetooth to a module at the uBitx.

Re: ubitx code version 4.3 for review, testing

Hi Martin:

Not a problem. One other thing: If your project includes a header file (which it should for multiple files), it should be included as:

?? #include "myHeaderFile.h"

and not

? #include <myHeaderFile.h>

If you use angle brackets (<>), the compiler only looks in the IDE's libraries subdirectory and default include path for the IDE. By using double quotes, the compiler first looks in the sketch directory for the header file and then on the default include path. You will need to have data declarations in the header file for any globals that are used in multiple source files. To get the most help from the compiler in terms of debugging, there should only be one *.ino file in a project--the file that contains setup() and loop(). All the rest should be *.cpp and a header file (*.h). The globals are defined in the *.ino file, but declared in the *.h file. (Define and declare are NOT the same thing, even though programmers are incredibly sloppy when using these terms.) If you use all *.ino files, you lose type checking across source files...bugs love to hide there!

Alas, I don't know anything about compiling on the Mac, but you can ignore the invalid conversion warnings as the compiler can usually resolve those types of warnings. Did you reboot the machine after installing the drivers? I don't know about the Mac, but sometimes driver installation on some versions of Windows doesn't "take" for all applications until the DLL gets registered by the op system. Can't hurt to try.

Re: RFI from uBitx TX after AGC and other mods installed

 

Hi Don - I tried a small RG174 cable and unfortunately it didn't solve the RFI problem.? Still getting a very strong garbled RFI when I transmit SSB and the audio cable is connected.? Grounded at both the pot end and the AGC board, with the center of the coax going to the hot side of the pot (not the wiper).??

Same problem with TX into a dummy load or antenna.??

Not sure what to try next unless I move the AGC board towards the front of the enclosure and redo the cabling.? I guess it's hard to know where the RF is coming from so I know the best way to route the cables to avoid it?

Any other thoughts?? Is anyone successfully using the AGC kit mounted at the tap point of the RF trace and Sunil's enclosure?? Maybe a photo showing cabling for a successful install would help.

73,
Rowland K4XD
