The BITX40 ordered on Feb 16 was shipped today via India Post. Got a tracking number, but no url where I can check it. 73! George VE7WQ Saturday, February 10, 2018, you wrote: VV> utilize the rest

Ryan: See if the attached encoder article is of any help. It should at least get you started playing around with the encoder. Jack, W8TEE To: [email protected] Sent: Friday, February 16, 2018

Mike, Mesure the voltage across the resistors and you know the resistors value. Calculate :if I remember right V2/R = Voltage squared divided by resistance to get the power dissipated. That should

It's probably worth mentioning that the "free" A1 refers to the original BITX40 code. Line 146 in that code shows: // #define ANALOG_KEYER (A1) which is commented out. If you do use that pin for the

Thanks for the responses so far, but what I REALLY want to know is if $100 is too high or too low to expect for all this stuff?

The other board was a VK3YE that he said did not work very well. -Fred KC3HMS <michael_r_monteith@...> wrote:

I have just finished chasing the smoking R141. Even after replacing the smd with an axial 1/2 watt, mounted vertically, it continued to get blazing hot after only 2-3 seconds of PTT. Be sure to check

Some more info and pictures for anyone wanting to use the uBitx on 160m. I’m having a blast on 160m I did add larger heat sinks and a pair of small fans that I can turn on and off as needed to

Steve, you need to install?the TX-RX mod so that the radio will go into TX when you press the button. Alternatively, you can press PTT manually on the mic and then press the tune button. 73 Allard

Thanks Mike, but according to this ( https://github.com/amunters/bitx40/blob/master/operating-instructions.md ) ,? ------------------------------------------------- CONNECTING A STRAIGHT MORSE KEY

Tune button? There is no tune button with Allard’s mods! Maybe you are thinking of the CW spot / fine tune button? This puts a tone on cw for allowing you to align the incoming signal with the

Hello All, I got Allard's Raduino sketch to compile on an Uno R3 that I'm playing with, and I also got a rotary encoder working on a test sketch, and now I need to figure out how to make Allard's

Hi gang.? I've got my '40 assembled, tested, and mounted in a box.? Loaded Allard's latest as well as all his hardware mods, with the exception of the TX-RX mod.? 6W output on SSB, but no output on

Hello Marco, Yes? I saw this cap on some schematics and they are supposed to flatten the gain curve. Thanks for the suggestion. I will have a look at this when I am finished with the audio

John, Have you tried putting a 150 to 330pf cap across pins 1 & 6 on T11? It might help balance the output. Most push-pull amps have this cap. Just a suggestion. Marco - KG5PRT

Thank you to those who responded to my question. Bill Richardson’s informing me of the contrast control on the back of the VFO module did the trick. It was originally set to maximum. Now that the

Rlacement of MOSfets alone can't not solve the case. ?However there is reasonable improvement,. Interestingly, there is a dip in gain at 21.2MHz and recovered at 28 MHz. Twe need to analyse this

The same would be true for the RD16Hxxx devices, incidentally. john AD5YE
