Evans, and group. Grateful for the help. I see in the diagram that TXA drives relay KT1, TXB the KT2 and TXC the KT3. For 10, 12 and 15m how should these relay combinations be? Do you tell me that 10m

I will assume that this is a v6. Based on that assumption, I would verify that one of the LPF filter relays has a bad contact on the NO position or it may be stuck on, as all are off for the 10m band

Hi all, No Power Out in: 10m, 12m and 15m. Note: There was a power fluctuation problem in digital mode - JTDX (FT8), observed at 40m, with the help of the group, I checked the option "Fake It" (JTDX),

TNX Raj,

Yes, center pin is +ve. V6 is reverse polarity protected! Raj

Hi all, New v6 user here and have assembled the kit, placed in the box and just need to connect up the power cable. I have searched through the instructions on the web and even gone through some of th

CAT is working Reed, I think I was just coding tired. Your firmware is great! Rafael

Hi, Anyone know where to find code for fat big number plus dot fonts for arduino? I really don't like the small fonts. ; ) Rafael PU2UIT

Hi Reed, The pins are working fine (after reverting the init order like Farhan's firmare). I'm writing my own code to talk to the radio over serial [1], and the same that works with official firmware,

Hi Rafael, I don't think you should be setting A6 and A7 as inputs at all. They aren't normal pins (they're ADC only), so they don't have the same options/routines as the other pins do. I'm actually a

Tom, Yes, linux latency depends on what other software is running. If I write an iambic keyer routine that shuts down all other interrupts and sits there polling the dot and dash paddles till everythi

Looping an RPi USB port connection from some SDR software back into an RPi USB port connection to our uBitx firmware would be a horrible kludge. I should have added a smiley face to that suggestion. T

Hi Jerry, That was an interesting link. Seems like the latency for Linux to respond to interrupts is all over the place. From sub milliseconds to hundred or so milliseconds. May depend a lot on what e

The RPI USB interface will work with an external (powered) USB hub. With a 10 port hub it is unkikely that you would run out of USB interfaces. Arv _-_

James, Interesting. Glad to see the si5351bx routines ported to whatever you are most comfortable with. A few comments: > # Note: Possible subtle bug in si5351_setfreq() Nope, not a bug. The only bug

Hi James, That is totally cool. I'm an old time Perl person, also. https://metacpan.org/pod/AI::PredictionClient::InceptionClient As well as liking Perl, I'm able to work from a nice mountain town bec

Tom: I have an si5351 driver working on a 3B+. It's a port of Jerry's uBitx driver in Perl with much more annotation to enhance understanding of the register gymnastics. It should be an easy port to P

When I first got a V3 in 2018, I noticed the variation in power output (exactly as Mick showed in his graph) using ft8. If wanting the most power, the frequency had to be chosen carefully. Didn't real
