The other way is to use various resistors to emulate what the potentiate does. But finding exact resistors and getting predictable and consistent results may be difficult.

you can program a push button to circle through a set of five frequencies

IMO keep the Raduino, get a 5 way switch and ground the various pins, each calling a specific freq in the raduino's arduino sketch. No LCD needed but you'd get the benefits of fixed channels that are

Hi Rob, yes, I have the same problem but it is easy to fix. If you select another component will get cleared. Contrary you select? "seleziona" (select)? and then go back to the screen and press

Wafer Connectors (mounts on the board, has a 'key' so housing is always connected correct orientation) ...and Pin Housings (holds the pins, terminates your wire(s)) Crimp Pins (down at the bottom)

Hi all: Does anyone know a way to replace the raduino and set the BITX40 to be use on 5 fixed channels. The project is to setup two small rig for emergency use self contained with LiPO and a tuned

All: Next week I'm going to propose a club build of the BITX40. However, I plan on using the Mega2560 Pro Mini and a TFT display. I've looked on the site and it appears that just buying the board at

Hello Don, By checking that the audio amplifier is working you have already started back tracking the circuit. Have you got a RF probe or oscilloscope etc. for RF voltage measurements ? If not make a

Nice and inspiring video & I liked the Heil PR-0 thanks

All: I took the Raduino source code and tried to compile it under the Arduino IDE 1.8.1 and it would not compile. I traced it to the fact that I was using a newer version of the Si5351 library. I knew

Do you have any photos of the connectors you're talking about? Roy WA0YMH

Gian, Thank you for the Link to Fidocad. I've just downloaded it and been playing around drawing a pcb. Nearly straightforward with the supplied and downloaded libraries. Especially the Arduino one.

Poor cigars, now where are you keeping them ?

Hi Farhan, it is a simple graphic program FidoCadJ developed by an italian engineer several years ago and expanded and updated nearly one year ago. It is for just over stupid people ... hi. It has

Hi Jerry That's good to know that others reached the same conclusions that I did. In the QRP Labs kits I am using only 32-bit arithmetic for all the Si5351A computations. There is one place where

You can use the snap off connectors. Snap off as much as you require, solder the wires and slip a piece of sleeve over the connections. Lawrence

HA HA! I started this thread and just today noticed the typo in the Subject: line. I just want you to know my board is quite happy, as am I. That is meant to say Bitx40 SMD board. Thomas W Noel KF7RSF

I used AD8950 module based oscillator and?this too has the click sound while tuning.? Probably the same reason. regardsSajeesh To: [email protected] Sent: Wednesday, 1 February 2017 1:59 PM Subject:
