I find it's easier to get the strip started if I put down a strip of double-sided sticky tape on a piece of cardboard, put the carrier for the SMD on the strip and use a small piece of tape on the

I used another mic housing with a DPDT switch and wired it so voltage is supplied only when PTT is engaged. I am using a CR2032 3v button cell. Seems to work fine, but I have not compared the stock

Which STM32??? There's a whole bunch of them, from Arm Cortex M0's to M7F's. The M0 is extremely cheap, can be well under a buck for the chip. The M7F has caches,memory mapping, and floating point,

Although not strictly required, it is recommended to remove C91/C92 for better performance in USB mode. C91/C92 used to be required for the analog VFO. You can safely remove them when the Raduino is

The inductors for the Bitx40 are described by Farhan at the bottom of ? ??http://www.hfsignals.com/index.php/2017/11/23/bitx40-circuit-description/ If you want to buy cores, I'd first look at? ?

Might be my problem too as discussed in another thread here today. Missed that C91/91 removal in the latest sketch comments. KC9SGV

I had reports of it being muddy. I will try and make another recording w/o it and try and get it posted when I have more time to play with it. Over all it seems to be an improvement but will have to

Umm, actually he will need to go from Farhan's stock firmwre to v1 or v2 of Allard's firmware. Either that or hack the analog BFO such that it operates 3 or 4 khz higher than the usual

Yes to your question C91/91 will attenuate the usb signal to much so they should be removed. You do not have to change firmware or go to V2 for this to work -- David ?N8DAH Kit-Projects.com (

No, the BitX40 code and the related hardware mods were developed specifically for the BitX40. The code is NOT compatible to the ?BITX! 73 Allard PE1NWL

USB is best done on the Bitx40 by upgrading to Allard's firmware: ? ??https://github.com/amunters/ You need to choose between his Bitx40 and Bitx40-raduino-v2 branches. Both take some minor

T2 on my Bitx40 is intermittent. By that I mean, if I nudge it my receiver cuts out, if I move it, it comes back on. I have re-soldered the circuit board connections and have removed T2 from an old

I may be late to the party, but I have just discovered the NEXTION?display. I am using it on my BitX. What makes it really neat is the software that can be downloaded from the manufacturer's site. It

Hello everyone! I want to buy bitx40 and use it as my portable station. I mostly operate digital modes and I am looking for help to add USB mod to bitx40. I have found some information for that mod
