Further updates on the TSW website, www.w0eb.com to make things a bit more readable and correct some spelling/grammar. Not totally correct yet probably but a lot better than in the past. Hopefully muc

Hi all! Well I guess I am one of those that the uBitx V6 came to me off frequency and the BFO is not set I have just put together a uBitx V6 and would like to know how do you connect it to your laptop

As I understand it, the first IF frequency of the uBITX (v6) is 45 MHz. In the original code, there is a variable firstIF, which is assigned a value of 45005000L. This appears to be 5000 Hz off Why? 7

I had a V4 but sold it because I wasn't using it that much and I was concerned about it not meeting TX purity standards. It was a fun rig though. So I'm thinking about getting a V6 because it appears

Hello Friends We had promised a new kit for Bitx are ready now and available in limited numbers. The Easy Bitx kit is a mono bander kit which can be used for 20mt 40mt or 80mt band. Te kit is sold as

I did as Ashhar suggested in the hardware writeup and used pencil and paper to work out the mixing details and sideband inversion. The 45 MHz IF is filtered with a 45 MHz bandpass filter. I'm assuming

What is the URL? Jack, W8TEE

Hello everyone. Im selling my uBitx v4 (one of them) with upgrades included. It's assembled into DU2RK 3d printed case, have the ND6T AGC board on it, audio mod done and Axicom relays. Y also include

Curious is there an easy way to access a point to transmit a small carrier (50%?) to adjust your tuner? -- Frank, KG9H

Can someone figure this out? I hear a weak image of an AM broadcaster about 30 miles away (820 kHz - verified by the station ID) on 21292.90 kHz on my uBITX. I don't see a relationship between the fre

Farhan's AGC and a Nextion S-meter Hi. I have built the amateurradiokits AGC board, but will not be using the mechanical S-meter on my V4 since I have a Nextion screen and an extra Arduino. I wonder i

I bought the Antuino (see details on hfsignals website) antenna analyzer (plus many other capabilities) and checked my HF and 2M antennas. I've had it for about one week. I realized that I have done w

See the TSW website at www.w0eb.com for details. The new TSW T4.1 Raduino kit is now available. Jim, W0EB

It looks like CW transmission is actually sideband modulated by a frequency that is switched on and off, rather than switching the carrier on and off. Is this correct? If this is the case, would micro

In the 6.1 code, I can see where the transmit frequency is shifted up (USB) or down (LSB) by the sidetone frequency. I tuned in the transmit signal on my IC7610 and see that this is definitely the cas

There are 4 different TX filters, controlled by 3 signal pins. In the firmware source code, there is are comments: 21 MHz and up: the default filter is with 35 MHz cut-off, (all of the TX_LPF_x pins a

After some years of lying fallow, I have found my round tuitt to assemble Farhan's bitx40. I need to make Allard's recommended mods. It would greatly help me if some kind person could email me images

I hope this question is appropriate here, since this is a problem when compiling my uBITx code. I'm using VSCode to do my Arduino coding. It took some setting up, but it is working well most of the ti

I now have my ubitx20 v5 assembled. I was working fine and I had begun the alignment process. Then it occurred to me to load the KD8CEC firmware rather than going thru alignment twice. I have loaded s

Just got a message from my son in Sacramento, CA re the birdies he received all over the place, even in his IC-730. This is to alert the group that when we get QRM in our radios, it may not be what we
