er...? Make that nice project TOM !

Hi Tom, et. all, Nice project, Bob... I am rebuilding my homebrew amplifier (I use it with my K2) and would very much like to incorporate auto filter selection.?? I have 7 filters rather than 5,

Thanks for the link

Yes, attenuates signals on receive by positioning them on the skirt of the 45mhz crystal filter. Might also be used for SSB transmit ALC if you are into that. Idea originated with VK2ETA ?

No not for calibration. It is to attenuate strong signals. I get a lot of powerful stations that saturate the audio Thanks for agreeing with me Evan.

Yes Evan, That is what I too observed. I wonder whether it has some thing to do with Calibration?

Well guess I am the dummy !! Got rig going on SSB then revisited the settings and on CW found all the options? that I had not realised were there!! So set up straight key and the time to stay on

If you have the Nextion display you will see a red rectangle show up that you can slide left or right to move the filter frequency tak8ng advantage of the 45mhz crystal filter to attenuate the

The attenuator varies from 0-254 If you switch over to the nextion display it becomes a slider on the main screen. Too loud just slide it to the right. Beats digging through the menus.

Terry, Nothing much. Attenuate 0 should mean the same of it being OFF. Raj

hi i have kd8cec version 1.097 the manual does not explain what the menu item att does on switch on it says att on i assume att means attenuator. i sleeted it and it said att on on selection i saw

John rarely can we blame a mechanical connection for diminished audio - and you can certainly press on the connection to confirm.? is the CW sidetone still loud?? that would confirm part of the

John, Firstly I am thinking socket or plug wiring problem. Check by directly connecting a speaker to the two speaker leads from the board. Next maybe some component failure in audio amp. Connect an

When built and tested on air, V4 uBITx,? I had good audio from the speaker and good audio on transmit.. I could never get the supplied socket to work for me. I just pushed the speaker mono plug

The ubitx is an impressive value for the price and a learning tool at the same time. Should be a requisite to pass the exam!!! :)

Dave, I have a BITX40 unbuilt kit, as received from India. Drop me an e-mail if you are interested. My e-mail address may be easily found on the 'net. Regards, Mark, G4FPH.

Welcome to the group Ross. I am sure you will enjoy the build. I certainly did. We are ready for your questions. There are very knowledgeable people here (I am not including myself in that category,

In Photos under my call (ab7vf)? I've uploaded photo of -20 db tap (goes between transmitter output and dummy load) easy, peasy 20 db loss without adjustment ...scale it for -30 or -40 db as needed

Woohoo, ordered the ubitx just before Christmas and got it yesterday. ?Not since Western Australia is just down the way from India. ?Iwas in a radio club in high school, I am 63, so a late returner
