Hmm, surprising.
The sketch provides more functions, but if they are not being used they can't generate extra noise or birdies.
Did you use v1.14 or v1.14.1? There was indeed a small bug in 1.14 which caused some ticking noise, and it was corrected in 1.14.1.
And have you tried different VFO drive levels to minimize the birdie?

Another thought: Perhaps the noise comes from the hardware modifications related to the sketch. Perhaps some extra noise is picked up by the wires to/from the function button, PTTsense, CW carriers ,etc?

Hi all,

Before couple of days I write mail that confirm the same thing.
Old raduino source in my old homebrew rigs (I have 4 homebrew cw rigs with modded raduino and Si570, AD9851 and Si5351) ,
don't have tuning clicks (Or they are in very low level).

Raduino V1.01 birdie at 7.200MHz is very low in signal, only thing I really missed is support for 10 Turn Pot.
ND6T software low noise and low signal Birdie, but I do not like shuffle tuning

result is I am going to use the old version since I have other Rigs for CW on 7MHz

Re: UBitx LSB to USB change

 

first, for psk31 (bpsk, which is what almost everybody uses), you don't have to flip the sideband. both sidebands work just as well (like they would for CW).
The easiest way to flip sidebands is with software. If the VFO is programmed range from 19.0 to 19.3 MHz, then it will generate the 7 Mhz as 19Mhz - 12Mhz. The minus twelve mhz means, that if the 12 increases to 12.001 MHz, the signal will shift to 19-12.001 = 6.9999 Mhz, that is downwards, hence you will flip the sideband.

Re: Standoffs for mounting the board

 

David, the correct tap for the bitx standoffs in metric size is M3 x 0.50 (M3 is the diameter of the bolt, and 0.50 is the thread spacing)

Re: Standoffs for mounting the board

Chart shows two rows of thread designations on the left. One row is for NF (National Fine) and the other is for NC (National Coarse). Each screw size has one entry in each column. To the right is a column of standard drill sizes. Drill bits come in large kits that have three overlapping size designations. One set is fractional sizes such as 1/8¡±, or 17/64¡± etc. Another set is in Letters A-Z, and the third is numbered. This chart is using the numbered series.

A search will turn up more detailed charts that indicate proper size hole for clearance (pass the screw through the hole) as well as proper size for tapping and that take into consideration the type of material being tapped. Tapping hole for steel is usually larger than for aluminum to allow deeper threads for strength.

All of this is educational but moot, as this is all an SAE or English size chart. You need the same thing for Metric sizes.

TFT/VFO Code and PCB Update

Jack Purdum
 

All:

Attached is an updated assembly manual for the TFT/VFO PCB I talked about at FDIM. Read the manual completely before building the board. I am also attaching the code for the TFT display and the VFO. There are two code files and there are directions for setting up those files for the Arduino IDE in the manual. Hopefully, the code is fairly easy to read. Some things I'm happy about; others I'm not. First, even without calibrating the AD9850, the frequency error is only 0.0000087% at 7MHz. After calibration (as explained in the manual), I cannot measure the error...if there is one. It looks dead-nuts on to me. Second, the keyer is simple, but works. I haven't told how to add the CW message switches yet, but most of you know how to do that. (I will be adding it to the manual, but wanted to get this out there ASAP.) Also, you can add paddles from your keyer and use the rig as a code practice oscillator right now. Dennis is finishing up the CW (and other) mods so I will have to change the code what that gets finished. And that's what I'm not happy about: The AGC, S meter, speech compressor, and CW mode is not implemented yet. You'll have that as soon as we get it done.

Note, the code is NOT a replacement for the work done by Allard. My PCB uses the Arduino MEGA 2560 Pro Mini and the Ad9850 (Type II) board which is vastly different that the Raduino board shipped with the standard BITX40.

I have more PCB's now and can begin shipping those. If you wanted multiple boards, but only got one before, please reorder. On foreign orders, I tried sending two orders as First Class mail in an envelop to get the costs down. One came back; hopefully the other one made it through. But, I'm not going to take the chance. All boards will go Parcel Post from now on. If you are in a foreign country, 4 boards go for the price of 1, so combine orders if you have a friend who wants one. Sorry guys, but foreign orders are $15, period. The additional postage averages about $11 and I have to fill out the export forms, which is a pain in the butt. Trust me, I'm not getting rich on you guys. US orders are still $7.50. Please note:

1. My paypal account is: ? econjack@... ? ? ? ? ? ? ? ?(please don't use any other account)
2. When you pay, there is a place where you can add a note: please write your shipping address in that note.

If you find bugs in the software, let me know as soon as possible and I'll try to correct them as fast as I can.

Jack, W8TEE

On the use of cutting fluids-? different metals require different cutting fluids.? I use tapmagic brand (USA),? the no#1 tapmatic(yellow) is for ALL ferrous metals. The no#2 tapmatic (red) is for alluminium. It works great for brass and copper as well.....
Work slowly, reversing the direction of turning to release the chips and DON'T TILT the tap...

Re: Yet another Raduino PCB

 

Sending Photos did not work?
Do it this way.


Yet another Raduino PCB

 

This is yet another Raduino PCB designed to add some features.

1) I wanted to be able to plug Nano in and wanted the USB connect next to the side of the cabinet so I can program without
taking the lid off.? I will make a small hole.

2) Added more filtering and conditioning on the power input.

3) Added a dedicated connector for Rotary Encoder.

4) Added an I2C connector.

5) I wanted proper Level Shifting to the Si 3V part.? Added FETs and pullups for that.

6) Added D0 and D1 pins on PCB.

7) Kept power and VFO connector on 5P header so no changes to my present wiring was necessary.

8) Put contrast Pot where you can get to it.

I think I added photos to this post correctly?

Take a look if you are interested.

But if so I would have been wrong.

Amp readings on Bitx40

 

Jerry and all,
I've read all the answers that you sent me and others about the power usage for setup.
My question is: Farans instruction (part 8 second bullet) say::
  • "Switch on the transceiver. There should be a soft hiss from the speaker. The transceiver should draw 150-140 mA in receive mode."
    This is approximately my current draw at receive. ?You have mentioned something quite lower ( 35-40 ma). ?What am I missing.
    Thanks, Andy


Re: UBitx LSB to USB change
