Mine was working fine for a week, receiving fine also. ?I was trying to adjust the two post to see if maybe turning them to the left would make a difference in the TX output. ?In the past I had only

error found !!!!! headphone connected to LM386 pin 5 and there is audio ...... looking in diagram it must be C111 there have to be changed

that's where I am right now... no display.

Have any of you guys seen this where the display shows black boxes all the way across the top line of the display?

My bad...and stupid. If you changed the symbolic constants up near line 121 and 122, then use the following at lines 1415-1418 ? ? ? ? ? if (flag == -1) { ? ? ? ? ? ? ? ? ? // Too low?

If you have a scope, connect it to OUT2 on the board. You should see a sine wave. Jack, W8TEE To: [email protected] Sent: Friday, July 14, 2017 3:12 PM Subject: Re: [BITX20] W8TEE TFT/ VFO DISPLAY

I expect speaker is ok, have tested it with a 1,5V batt. and it gives a " blob"? everything have worked until I made a complete rewiring and connected parts for CW ! I do not use connectors instead I

hmm... I had a blocking Display at 7200 too when I change the bandend to 7200 because I have forgotten to change Line 1417. :-D The default is 7030 if no?EEPROM recorded before. You maybe check the

All: I just uploaded a table that shows the pin assignments for my MEGA2560 Pro Mini TFT/VFO PCB versus Allard's Nano pin assignments as of his release 1.18 for the Raduino. Look for a file that

Hi Jack I am using a KY040 connected to the correct pins…I get the feeling I have an issue with the DDS because if I remove it, the code behaves in the same way without it. Unfortunately I do not

Hi Matt No, I just compiled the latest version of the code and the default seems to be 7.200. I think I have a problem with the DDS which I got from China, There is no output :( 73, Charlie GI4FUE

Thank you Jack! And don't be afraid of the alligators... ;-) 73 Matt, DH2LAB

I definitely need to buy a power supply like Nippon America... my computer power supply was a noise source... Now I'm testing the radio with my jump starter and works fine... antenna on the video is

How is the speaker? Celso - PY2XT. ? De: madsen1960@... Enviada: Sexta-feira, 14 de Julho de 2017 00:39 Para: [email protected] Assunto: [BITX20] blown LM 386 ? D18 is ok ! about 12V on both

The PCB schematic has been posted, but I've reattached it here. If you look on the upper-left corner of the PCB, you will see OUT2 and GND (yellow header). That is the buffered output of the VFO and

The only flicker I've noticed is when the Voltage field is updated and I've done about as much as I can to eliminate it. I have zero flicker when tuning. Jack, W8TEE To: [email protected] Sent: Friday,

Other that those for the encoder, the header I/O pins are not labeled. There's not enough pico acres on the PCB to do a good silk screen. Use a continuity tester from the Mega pin to a header pin to

Usually, failure is because the clock and data lines are not connected to the proper I/O lines on the controller. What type of encoder are you using? Jack, W8TEE To: [email protected] Sent: Friday,

Hi Charlie; did you change the Bandend to 7200 for Europe? If you did so, you have also change line 1417. 73, Matt DH2LAB

Having successfully completed the build according to instructions I'm now looking for a Pin numbering of the outside headers as well as wireup instructions for connecting to BitX board as i'm not sure
