Re: Micro bitx in the spectrum analyzer
#ubitx
i hope you guys are using sufficient attenuation ahead of the spectrum analyzer. typically, if you change the attenuation, the harmonica and the fundamental should fall exactly the same dbs. - f

uBitx Case and speaker for sale
I have decided to go in a different direction and use another type case to build my uBitx radio.
So I would like to sell a case along with an 8 ohm speaker and also a roll of Copper Foil.? The case was produced by Carl Beck.? The speaker is the one he suggested to use with the radio. All are new, never been used, as I have purchased them recently.
I paid approximately $65 for the items.? I will sell for $60 plus $10 for shipping within CONUS -- USPS Priority mail. Please pay by PayPal to rickocr2005 at yahoo.com.
Thanks and 73

Thanks Mike.? Usually when I order something online (and I do that a LOT!), I get a notice
from the vendor that they have my order and, sometimes, give me an estimated date for shipment.
Just looking forward to getting this kit to play with.

Re: uBITX Firmware CEC Version 1.06 Release (Added WSPR)
#ubitx
Hi Ian.
I am afraid that the LPF selection problem is back with V1.06.
Need to select the correct band before doing a WSPR beacon. The same as V1.05, before V1.051.

Micro bitx in the spectrum analyzer
#ubitx
Testing with the micro bitx in the spectrum analyzer, I found that the harmonics reduction is very low. Has anyone else done this measurement to compare?
The photos are 3 per band (fundamental, second harmonic and third harmonic).

Fw: Re: [BITX20] uBITX EEPROM MAP
My bad...I didn't even think of those calls. In the main INO file are the following defines:
/**
* These are the indices where these user changable settinngs are stored in the EEPROM
*/
#define MASTER_CAL 0
#define LSB_CAL 4
#define USB_CAL 8
#define SIDE_TONE 12
//these are ids of the vfos as well as their offset into the eeprom storage, don't change these 'magic' values
#define VFO_A 16
#define VFO_B 20
#define CW_SIDETONE 24
#define CW_SPEED 28
These are byte offsets into the EEPROM address space. Because LSB_CAL is offset by 4 bytes, we know that MASTER_CAL takes 4 bytes (i.e., 0-3) and is likely a long data type. Because an int can have a value of 32,767, SIDE_TONE's memory requirements could be reduced, as could CW_SIDETONE. CW_SPEED could be a byte value since an unsiged byte can have a value of 255. That's over my current WPM CW speed.
Anyway, you could write a short program that would write values to EEPROM using values that make sense for you, or you could just run the program and use the menu items associated with each constant, since the code writes the new values to EEPROM.

uBITX Firmware CEC Version 1.06 Release (Added WSPR)
#ubitx
All The test period was extended because some features were added before Version 1.06 was released.
I released version 1.06 which added WSPR function to uBITX.Beta testers have been very helpful when embedding WSPR functionality. WSPR will continue to improve in the future.By using WSPR before and after QSO, you can check where your uBITX is spreading all over the world.??If uBITX Manager is used to put WSPR information into uBITX, uBITX no longer needs any external device to transmit WSPR.Added or improved in version 1.06 1.Added WSPR function to uBITX
2.Update uBITX Manager to Version 1.03.Reduce program size
4.Fixed IF Shift Bug
5.Bugs fixed
7.In CWL and CWU mode, it is possible to manage the use of two options which are displayed by shifting frequency.CWL, CWU mode can be used more easily.
Please see the link below for details. You can download HEX file and uBITX Manager from the link above.?You can also download the source code at https://github.com/phdlee/ubitx and see all the changes I've made so far. If there is a non-critical bug in the public version, I will link to the new firmware in the above blog.
Thanks for reading.

Good luck setting the sidetone within the calibration menu of the original uBitx code.
In file ubitx_menu.ino, I see this line at the end of menuSetupCwTone()
? ? EEPROM.put(CW_SIDETONE, usbCarrier)
That would set the CW sidetone to something like 12mhz instead of around 800 hz.

Just looking over the code, I see this in? ubitx_20.ino? from? ? All are 32 bit integers.
#########################################
/**?* These are the indices where these user changable settinngs are stored? in the EEPROM?*/
#define MASTER_CAL 0
#define LSB_CAL 4
#define USB_CAL 8
#define SIDE_TONE 12
//these are ids of the vfos as well as their offset into the eeprom storage, don't change these 'magic' values
#define VFO_A 16
#define VFO_B 20
#define CW_SIDETONE 24
#define CW_SPEED 28
###############################
MASTER_CAL and USB_CAL must be set for anything to work, probably what's messing you up. CW_SIDETONE determines the rx freq offset when in cw mode, in addition to the CW sidetone in Hz. CW_SPEED is 1200/wpm,? so the value of 100 makes it 12 wpm All of the above can be adjusted within the calibration menu. VFO_A and VFO_B can be set to some operating freq in Hz, defaults are 7150000 and 14200000
vfoA=7150000L, vfoB=14200000L
SIDE_TONE and USB_CAL never get used. Here's some good default settings: ############################### MASTER_CAL:? ?0 USB_CAL:? 11997000 CW_SIDETONE:? 800 CW_SPEED:? 100 ############################### Jerry, KE7ER
