I wasn't totally happy with the screen captures I got yesterday when I posted the initial spectrum test with the new SSA 3021x spectrum analyzer so I re-ran them this morning and paid a lot more

OK then, assembly and testing at the bench before it goes in the case! wrote:

Not a problem, Jim. When I get mine I'll do the test. For spurs you shouldn't need a two-tone generator, just a simple audio oscillator. You might want to make sure you aren't seeing some kind of

Harvey I am not familiar with what these voltages should be, but a factor of 10 in voltage doesn't readily sound excessive. I honestly would consider whether your microphone is giving enough drive, or

What frequency is the signal going INTO the 45MHz filter? -a

Assemble it and test it to make sure it works. Are you going to do the amunter mods to add CW, etc? If so, just assemble it and make the mods one at a time and test. When you have a fully functional

I'm troubleshooting low SSB output, about 2 watts, from my V4 uBITX. In making measurements I find I have a 400mv SSB signal going into the 45MHz filter, Y1, but only 40mv coming out of the filter at

Didn't mean to confuse anyone, Thought I'd talked about the new layout making for improvements?? But made a mistake mentioning yours as a V4 when it's a V5 so sorry about that.? Regardless, all my

Jim, I have used the following tone generator on my PC with a simple jumper cable made from a PC headphone jack and the standard Tip Ring Sleeve that us used in the uBitx.? I also added a slide

The way you stated it though might have confused newbies. You need to make certain they know WHY you are posting V3/V4 info in relation to V5, not just post your measurements. If you don't you might

Andy, Well, that's over my head. I did get some PCB's from a Chinese firm using these files, but as I've not built it up yet, I have no idea whether or not it's done right. I have no problems reading

Once again, Yes Jim I understand that.? I thought you/we/someone might be interested in seeing the improvements in the new version. Anyway, your tests are fun to see.? Thanks for all your efforts!?

Hi Doug Sorry, making assumptions here. It's the uBITX multiband radio. I did get this a few weeks ago from HFsignals.com. Bob -- Bob Head, Rotronics Systems Limited, 01252 722686

No paste No problem Sorry to hear about your friend. Thanks for the status update Dan W3BU

Bob, What radio do you actually have?? This list covers the entire BITX family.? The name is a hold over from Farhan's first BITX, the *20*.? You referred to a BITX20 kit delivered via India post

All, I was going to say "let someone who operates SSB do this", as I don't even have the microphone audio connected on any of my uBITX radios, but I came to the conclusion that I'd be doing the group

Hello all. I've just received my new BITx20 transceiver via IndiaPost. It arrived quicker than predicted and the 'kit' is very nicely assembled. Checked it mechanically and all is well, toroids all

Mark, You're comparing apples to oranges here. My tests were on the new Version 5 board with the new LPF switching sequence and new IF frequency, NOT a V3 or V4. Jim

Exactly Frahan. I have never bought a commercial antenna and have always made my own including a 2 El Quad for 20, 15 and 10M. This includes antennas from 160 to 2M, including 6 and 4M. Have a look at

HI Bruce looked at the u tube of installing the new firmware .but it assumed you had the installation manual ..Can not find the? installation manual for this down load to install it into the BITX
