I haven't ordered my uBITX yet, but I am very excited about the idea of a 2m SSB radio. I could probably only use it while in the States(summers), because I just don't think there'll be any activity where I'm at during the school year, but I would still love the idea of using it while traveling during the summers.

I've had good luck with Tayda, too. However, some of their stuff comes from a distribution warehouse in Livingston, CO, so sometimes the delivery time depends upon what you ordered. "Odd stuff" probably comes from Thailand and takes a little longer, but still faster than from China in most cases.

A very thin copper wire supported by fishing line would be invisible.
I had a 160M dipole supported at the centre like this for ages way back.
I had actually used a length of very thin intercom cable and it was practically invisible. 
So a very thin copper wire supported by a fishing line will be invisible.

I just buried 32 radials for a flagpole antenna I am installing for HF. I have an MFJ loop antenna in my attic as well as several vhf and uhf antennas.

My previous location was 30 feet ASL with a 50 foot tower so with the HOA I am still 50 feet higher. I had to sell the crossed Yagi antennas I used for space stuff but I'll get over it.

for Ken and Steve, if you want compact antenni you really need to look into loop antenni, it's amazing what you can accomplish with some old Cable TV coax and an adjustable vacuum capacitor.  or soft copper tubing for that matter, some people have even managed to pass them off as "Lawn Art". I've even seen at least one example of a loop hidden under the table top of a plastic outdoor set.  with limited success there is the old standby of the rail gutters, and even the holiday lights for the creative!

Got the "OK" from Don and Ion so let me see what I can come up with and the schematics and board layout look fine to me. The only thing I would change is make C7 a 1uF cap. This will be a SMT board

Re: No PTT

John (vk2eta)
 

Hello Geoff,

Here is the beta version of the Diagnostic Software. It should at least get you started. Some instructions are in the README.MD file in the top directory.

Only main menu items 1 and 2 are implemented at this stage (core I2C tests and Analog I/Os).

I need to write a manual for this but I have been too busy coding it so that you could assess your Arduino..hihi

The main menu number 2 (Analogue inputs), brings a second level menu for testing the encoder inputs, the push button, the PTT, the Keyer and the spare analogue input.

Results are displayed in a horizontal bar graph with a scale from 0 to 5V representing the value read by the inputs. That way you can see how it matches the values your voltmeter indicates on the respective pin.

Results are shown only on changes to the values read, for example when rotating the encoder, pushing the PTT or the encoder push-button etc...

If no results are shown then your Arduino cannot read analogue inputs and it would mean plan-B unfortunately.

Let me know how you go with it.

All the best,

73, John (VK2ETA)

Thank you, Jerry & John,
  
I have a PC running  Windows XP and also Ubuntu/Linux, which I prefer. I have downloaded programs and run them, mostly with success. I usually use it as a word processor for my writing and browsing the internet. So, please, John, I would like to try your diagnostic software. 

Regards
Geoff

Hello Geoff,

I have the start of a diagnostic software, focused especially on your situation for now.

Setting up the Arduino development software is pretty easy. There are quantity of tutorials on the internet. Look for "Arduino IDE". You don;t need to download any additional libraries. The only hit and miss stuff is the driver for the USB port.

If you want to use it let me know I can post it here now, otherwise I will wait a few days until it is more complete to publish.

But it would be useful to check your analogue inputs and show you what the Arduino sees.

All the best,

Franco,

If you turn up the volume too much the chip heats up.. specially with 4 ohm speaker.
I blew up one non WX chip.

Instead of 12V you can feed the audio chip 9V from a regulator and you will be safe.

Hi Nikos, 

Do you recall how much image suppression you saw? 
By "ear", my radio seems to have quite poor receive image suppression. Changes to the USB and Master calibration values aren't having much affect on the unwanted sideband image.  

My current settings are:  
Master:  150000
USB: 11997285 

Thank you
