Re: odd behaviour with new library si5351 v2.02 => strong tuning clicks!
Thanks Don, for confirming this! I have updated URL in the Wiki so that it now points to the v2.0.1 library, instead of v2.0.3 by default. I used to have the tuning click problem in the past, and I

Re: Tuning POT not tuning
A thought, are you using the pot that came with the rig? A number of folks have gone to the 10 turn pots and not realize that pin 3 is the wiper. v/r Fred W4JLE Sent: Sunday, March 26, 2017

Re: extra surface mount component
This has been reported previously: ?/g/BITX20/topic/smd_cap/4525885 ( /g/BITX20/topic/smd_cap/4525885 ) I don't remember any resolution to this issue. Might be

Re: PTT line to Raduino?
Just remember the PTT is dealing with 12V and you never want that going to any input/output of the Raduino. The only exception is the 12 volts sent to the 5 volt regulator via the orange wire on the

Re: BITX40 Audio Indications for Modes And Frequency Readout
Should be possible, though I don't have lots of experience with the Arduino environment. ?Could do it on the Nano that comes with the Bitx40, though that's a tight fit. ?The Nano UART pins are used

extra surface mount component
Hi All I cannot find in the topic a reference to the extra surface mount component included in the Bitx40 kit. I know it is in there, but I can't find, and I don't know what the component is for.

BITX40 Audio Indications for Modes And Frequency Readout
Hi all. Sorry for what might be Arduino newbe questions, but your patience is appreciated. I'd like to add some things which would be helpful for people who can't see the display. I would like to

Re: am broadcast break throgh
Hi thank you for the pointers.? I will take another look at the pcd just to make sure there isn't a problem tomorrow.? I have ordered a new si5351 board and a arduino nano so will be putting it back

Re: Continuity
Thank you very much for the methodical approach to testing for power. I am happy to say that all connections have been made, as you suggested, and the radio is transmitting and receiving very nicely,

Re: PTT line to Raduino?
That last bit was bout that single side band. So to clarify which case is that character? Upper or lower? I am gonna take a break now so I don't stir up any nerd rage.

Re: Bitx40 low volume oscillation squeal
nothing ventured, nothing gained - I will see if I have one lying around and will give it a try. I still don't understand what causes this behaviour. I will have to breadboard the circuit and play

Re: PTT line to Raduino?
Damn, I did it again. Look at this-?It looks just like what's in the Arduino IDE except the top is not slanted down. Indicating a lower case L. You guys are right. I am glad I didn't make a bigger

Re: Tuning POT not tuning
Ok, we can close this topic now. I went to Fry's, bought a 10k linear pot. Replaced my broken one, and it works like a charm now. Thank everyone.

Re: Bitx40 low volume oscillation squeal
That is strange. This was the problem with mine and 2 others had the same problem. I am assuming your smd version is built the same as the through hole version. 73 Ken

Re: Bitx40 low volume oscillation squeal
I tried a second one and had the same behavior. I will dig through my junk box and see if I can find another to try. I am not sure how a pot that has dead zones on one or both ends would cause this

Re: odd behaviour with new library si5351 v2.02 => strong tuning clicks!
Allard, Confirmed. Both updates (0.2, 0.3) have 1.7ms gaps when reprogramming frequency. Best to revert to 2.0.1. N5KYD alerted me. -Don, ND6T

Re: PTT line to Raduino?
It is the letter L not the number one. You can determine this by using the” find” function under “edit”. If you search for 8001 (with a one) you will not find it in the referenced line but

Bitx40 First contact
Thought, why not..... 9A2L 59, well its a contest so what did I expect but just over 1400kms with under 5 watts. Bitx40 is still a PCB with wires hanging off it, no case as yet. Hopefully later this
