Lawrance, are you using uBITX with BAT54S as mixer diodes ? If you used 1n4148, then your tests could be valid. regards sarma vu3zmv

Since most keep talking about the need for BPFs for certain bands, I "guess" the 80m-10m uBITX direction should be a board with 6 filter capability. How about a?basic?dual relay?switched filter

In the interest of avoiding any confusion, I break this out to a separate thread. 73 Kees K5BCQ

Awesome

I'm not "dumping" on Ian, merely trying to get him to WAKE UP and fix the problems he's kept missing in his software. It could be really good for ALL modes if he'd just listen to what a few of us have

It has to be programmed to work that way, but we do it in all of our recent sketches. There is no reason why it can't be programmed in the other sketches if the programmer choses to do so. Jim

Well maybe no one is paying attention but our software has CAT control, S-meter display, Pass Band Tuning, and we build "memory manager" into the software so, you do not need a pc to change things. We

Beautiful case..?

Hi Allison You said that ( I measured not more than 3dbm at the mixer) mixer, which shows not enough rf drive. Ever thought of adding a small amplifier for more rf drive to the mixer with suitable

9h1avlaw? of course you risk outof band transmissions if you aren't at least able to recognize which WAY your sideband is going, and how close to the band edge you are.....exactly the same is true of

Jim… I think you may have missed many of the positive features of the Nextion display… and in particular BECAUSE of that editor, anyone can move those, how did you call it… clutter?, things

If you are near the band edge you risk out of band transmissions

Perfectly correct. On receive it is the BFO which must be offset and NOT the transmit frequency. When we had separate Tx and RX and the RX had a variable BFO (CR100/B28, CR300, Atalanta and their

Thank Jerry, but in all of the software put out by the Triumviratw Skonk Works from our first public release for the original NANO and ever since, CW has not only worked properly but the Keyer has

I ran a WSPR beacon with my uBITX for several weeks. I found that it was rare for the TX frequency to drift during a transmit cycle. And only a HZ if it did. I ran a fan on the heatsinks and the

This issue come up over and over. The factory software has (or at least originally had) the same issue. A comprise would be for the display to switch to the TX frequency when you key the transmitter

The ideas is to use exiting LPFs as is, with the option to add a fifth if you so chose, 160m... or better 10m.... But mainly better lay out and separate relays... I will provide a code snip-it for

Ian's software is the most popular update available for the uBitx. He has added a lot of functionality to the rig and that is to be applauded. It's taken months of free time for him to bring it to
