Just received this from hfsignals this morning: *"Orders received on Dec 17th are being shipped. Tracking details will be updated soon." * -- KK6VLV

The 8 pin and the 5 pin both have an orange wire. Easy to get confused. Dave

The "Transfer-oscillator" approach like Jerry suggested using an SA602 has been used for many years to look at things that slow oscilloscopes would otherwise not see. Arv

I would recommend in building these radios that you change All ground wires to Black and All Power (5 or 12V) to Red. Reserve these colors for just 2 purposes. You can use the wires you remove for

I also hooked the orange wires up wrong and it completly blew my nano so I had to replace my nano. Not a fun job. Lots of luck. Dave kc2ipx

T ?he C Programming Language (The K&R Manual) by Brian Kernigan and Dennis Ritchie was where most of us really old coders started, but Jack was not far behind.? I have a well worn copy of his

Very cool, good job! Thanks for the update, this may come up again. Could be that the old arduino had a faulty 16mhz crystal. But that thing is tiny, swapping in a different crystal would be

In v2, pin A2 is not used anymore. You could remap the function button to A2 instead of A3. at line 233: #define FBUTTON (A3) change to: #define FBUTTON (A2) 73 Allard PE1NWL

You are not alone! I had my bitx40 in pieces on my benchtop and wired the raduino using the orange I/O wire instead of the orange +12v wire...powered on....got nothing on my LCD...turned off...checked

Hi John,? I've completed the mod in the Rx path, and it is fine business. No problemo, I even think I have more tx per, but that's most likely due to lowering the noise gate on the ssm2167... Pics

Please submit your request to the email address in the PDF brochure.? I need to use my email Client to maintain a log.? Plus I will be able to respond to you as to an estimated completion date for

I apologize that I was not aware of all of this before I posted. My intent was good. That being said as parts, or if its possible to bring rf in to its range, or even just to help with the digital

Jerry, ?? I love the idea of using a SA612 type device to bring the frequency down.?? The STM32 micro could process the signal.? Over in the??STM32 Duino Forum ( http://www.stm32duino.com/ )

I too know a very good book, i just get it to my 70. years birthday from my daugters. It is called Beginning C for Arduino, second edition. ISBN 978-1-4842-0941-7. I sit with my PC, the Arduino and

I use the schematic on the hfsignals website. As far as I know, there is no pcb layout picture available. That's true; there is no RX path in TX mode now, because pin 16 is grounded. However, the mod

Hi John, there is no RX signal path on the relay when in TX mode.? I can't test it, I also search for the PCB layout but was not able to find it. Is there a PCB (schematic) layout in eagle

Update for this week... All the parts came in, finally got everything built up, just need to let the smoke out tomorrow. 1) Mechanical clearances are okay. Front panel mic/headphones need to move up

Hello Nick, I tried the filter in the antenna path and it works very well. So I will order some small toroids and try it in the Rx path when I receive them. Cheers, John (VK2ETA)

Problem solved. Just to re-state the issue: strong tones within the passband, mostly fixed in ferquency. Some slight variation in frequency when scanning through the menu items. Also strong tones
