Curtis, Very nice and well done. Much can be accomplished with simple hand tools, patience and practice. In my workshop my favourite tools are my Wilton vise mounted on a very sturdy workbench, a

All the cutting on the case was done with a hack saw, dremel tool, and file. When the top needs to be bent. I will do it by and also. It just takes time, patience, and just a little sweat. The sheet

In this area near Seattle there is a chain of metal supply shops called Metal Supermarkets. They specialize in cutting small quantity, small sized pieces at very reasonable prices. The guys at the

I recommend that you post a BITX40 Digital Meet Up in a post format similar to this one, with the time, date and frequency. I don't have digital working yet, so I can't join you.

All: I just posted a source code file for use with a 4x20 display using Allard's Rel. 1.20.1 code as the base. Essentially, it should accommodate both display sizes if you change the #define's that

I would be willing to do PSK this weekend as well. I will be on 7.070 Sunday evening but it will be a bit later when I get home from church. Probably 9pm Eastern or so. I will use Bitx in the CQ

I think I mentioned the fix earlier, but the change is in DoMenuSelect(). ?In the switch/case statement block, paste this code:? ?? case ENCODERTUNING:? ? ? encoderMode = ENCODERTUNING;? ? ?

Jeff Pls send a copy. I have serial display also Thanks 73 Art Sent from my iPhone

I went to a 4 line display some time ago. I am using the additional lines for an S meter and the last one is just my call. I am using the 1.17 sketch with just a few additional lines for the display.

I'd be happy to send you Allard's sketch I modified for the 4x20 display. It's totally untested as I don't have the display hooked up to my BITX40, but have attached it for anyone's use who cares to

Jack So my issue is a bit different. I can load and run ver 1.05. The encoder functions as the freq changes on the display. There is a sine wave via my scope from vfo out. However the freq readout on

It seems that the DDS output frequency issue only occurs at startup, before the encoder is rotated for the first time. Since that is the issue, the best place to put the "extra" sendFrequency() call

We did get some Mega 2560 Pro Mini's had issues with interrupt vector 5 and that was the reason for the change. Also, we are polling the switch, so almost any digital pin will work since it doesn't

I think it would work just fine with no changes to the program. The pot is acting as a voltage divider and the impedance of the arduino adc is so low it is negligible in this application. Sent from

HI, All In the sketch from Allard for the BITX 40 there is the possibility to use an 10 turn ?potmeter. In my junk-box I found one ?10 turn, but it is 5k Ohm. Could I use this one to ?or do I have

I do recommend adding a momentary switch for SPOT even if you only operate SSB, as holding it will put the rig into Fine Tune mode on SSB using Allard’s sketch. You might also consider adding a

Jack W8TEE recently modified the code so that it could handly a 4x20 display: Thanks Jack! Unfortunately I can't try it out as I only have the standard 2x16 display. Perhaps someone wants to try it

Well done Ted...

Congrats TED what are the Antenna and feeder details please !! sarma vu2zmv -- Regards Sarma

Ted, FB on the first contacts! In May I made a confirmed QSO with the Canary Islands (3965mi) from my QTH 50 mi NNW of Chicago with the BITX using a 10' center high trap dipole! This little radio is
