I am working on a new larger enclosure (Desktop/Base) for my uBITX and wanted to know your must have mods/upgrades to add to the design.? I plan to include a nextion touch display and builtin power

?ha, ha!! Next time I see that elusive fella I'll be sure to tell him you appreciated the hours and hours he spent! Cheers, Gordon ________________________________ Sent: Thursday, November

Thanks!? I feel a white noise/SDR test coming on. I'm using your books - thank you for documenting your work with Winlink and ALE!? And please pass on a 'thank you' to Mr. Prepperdoc as

Well, I suspect at LEAST 2 kHz. I think mine is more like 1800 hz. Optimal is probably 2.4 kHz If you’re short on bandwidth and things aren’t working, try the 500 Hz winmor mode in that should

I've been using mine for Winlink as well.? My sloping 'S' shaped 40/20 attic dipole isn't optimum by any means, and I sometimes have to jump from station to station to get a reply, but it does move

Hi Don, I pulled the board and tested with sig gen on input and only the scope on the output.? Same huge crossover distortion.? The (simple) circuit looked OK and the + input bias was 1/2 Vcc.?

No, left open.? Had not experienced a problem before this.?? But then, there is this ;) A new board using a 741 is working great. Woody? KZ4AK --

Try a 1458 instead. It has the same pin-out and is drop-in compatible with a much higher output capacity. I mention this since it appears that you are feeding a lower impedance than what it is capable

nothing is confirmed as of yet. let's keep discussing it out of this mailing list. i will post the confirmed date though. - f

Raj and group, Farhan was also suggesting a filter to remove the 12mhz spur in the transmitted output that resulted from crosstalk from clk0 into clk2 at the si5351. Should that be included in this

Well I’ve used them several times successfully. The audio band width is not quite as large as one would like. You can change some capacitors in the Crystal filter to fix that if you wish; I

Guys, This has nothing to do with the spurs issues. Just a test to see if the SMDs are as good as the toroids. I am pleased that smd is a good alternative at signal stages. For a cure all I stand by

Thanks please. i looked at that message and assumed without notiing the context. Thanks again regards sarma

Sharmaji, this is on a test jig.

I’m new to the group and to BTX kits so please excuse me if this has already been covered. I’m involved with emcomm wonder if anyone uses these small hf rigs with Winlink? If so would you please

Raj, is - 0.65 the total loss on a 50 ohm load for this filter on SSB? What is the CW loss on various bands?

Sarma, that is the LPF to remove spurs between the IF, so it will

Raj sir, will the smd inductors in post PA lpf mode, take that power?
