My guess would be to follow this schematic... and put in a second jack. You could also put (as I plan to) put a momentary push button across this (for when you don't have your key)

If your experience is similar to mine, it is very likely that you need to proceed with calibration of the VFO and the BFO, since the carrier frequencies fall outside of the (45 MHz and/or 12 MHz) pass

My uBitx (no mods) seems to be compliant on 20M SSB FT8 at around 9.5 W out (13.8V @1.2A in) Mike K5ESS

?IR2028 doesn't really seem to have ANYTHING on spurious responses. And I don't think you are really likely to exceed 10 W to the antenna if you stick to about 12V. So I don't see any real problems

Using a v4 uBITX with latest firmware. I have good audio level. Hook up the antenna, get a lot of static. Tune in for example 10.0 Mhz (and around that frequency) and nothing. Move antenna to my

Have just wired my new uBITX 4.3. Installed the 4k7 pullup resistor at CW input and pulled tehn the CW port A6 to GND - nothing. Because it is a ADC port I put a 10k pot between GND an 4k7 and got

I also have Sunil's case on a v4 uBITX board . Added the 2 resistors (10K and 2.2K) to my Paddle key. Configured the software for Paddle use (latest firmware from KD8CEC). Measured connectivity etc.

hi yes it appears that ofcom only checks that you are not causing interference. if you are not causing interference then there is no technical spec. of course interference has to be reported by

Hi?SP Bhatnagar Thank you for your reply , I eventually found the PTT define in the main code -? Many Thanks Alan

Also interesting to note that although operators with BASIC qualifications can only build from a kit, I can't find any Radio Standards Spec document applicable for kits or amateur equipment in

Here in the USA, the FCC gives us a hard and fast rule: From?http://www.ncvec.org/page.php?id=139 (d) For transmitters installed after January 1, 2003, the mean power of any spurious emission from a

Alan, PTT goes to pin 26. As of now the cw is not included. The external switches are not needed as all the functions are handled by touch. Even frequency can be adjusted by touch only. Encoder has a

Hi Terry Yes, appears similar ambiguity here in Canada

ps does the ubitx meet IR 2028 as my licence requires for foundation licence’s. i am an advanced licensee so it does not bother me but is it. terry gm4dso

Maybe the fuse, its holder, dc cable maybe? I would check first the DC, than the rest.

hi what’s all this about -43 db. my licence does not mention any db but simply that it should be as good as the state of amateur development permits. no mention of a spectrum analyser. copy of the

Why are we still having discussions on End Fed Antennas? Thought that was why the Antenna email list was started.? Cheers, Guy WB7SZI

Never mind.....I see Allison already answered this. Too many threads............ 73 Kees K5BCQ

I am 100% cw and have been using my version 3 ubitx and use G3cwi outboard dual band filter with good effect,Ihave added a 5k1 resistor on the keying line and now the cw keying works as it should do I
