I found my BITX 40 to be much better on receive than my old Sommerkamp FT277ZD on the same antenna. The difference was such that I could hear all the digital wurble with the BITX40 and not at all on

Sensitivity is fine. I have used an homemade norcal S3 generator to see if it could receive it and was right. I check all receivers with it and all from ham radio, mil rigs and cheap portables behave

One more comment. I was assuming your cable is intended for 5 volt digital logic connections, not actual RS-232. If it is RS-232 then the voltages may be an issue. But, you may be able to use limiting

See the posts in the 3/21-3/31 date range (look for “RD16HHF1 power curve flattening”)… We’ve been through this. There were SPICE simulations, changes to all of the RF stages (bypass caps),

tom, I suggest you keep the font color black! the grey makes it difficult to read. Raj

The QTC, the sweden's ham radio magazine has put the ubitx+rtl_sdr on par with some top rated ICOM dsp radio. You might want to see how that author did it. - f

I could have a balance?issue with the mixer diodes, I suppose. I'm using discrete BAT85 . . . not necessarily matched but from the same lot (Digi-Key). The BAT85 is electrically identical to the

You should be able to connect your FTDI cable directly to the D0 and D1 pins on the Nano. The onboard chip drives the serial data through 1K resistors and allows the D0 and D1 pins to override the

I don't see a way to re-edit a post, so here it is again, I hope, in an easier to read font. It looks like the issue is with writing in another editor and pasting that into the on-line editor here.

If there is a way to edit posted messages, I'll be glad to do that. (and fix a misspelling I see, also). I only see one size font that is not a "header" size though.

I fully agree, address the microphone audio, the frame power out issues and generally do a complete workaround on those things that have been addressed. As to the software, keep it simple and for

Tom, could you maybe use a larger font?? Just one size bigger.? My old eyes are struggling to read your message. -- ????? Lee - N9LO ???? "I Void Warranties"

When you see 26 and 19 Watts, what exactly are you looking at? What mods, and at what voltage to the drains? Jerry

I see a lot of good conversations here about improving the uBITX transmitter output. However, I see very little about how good the receiver is. My question is, have many people done comparisons of the

Yes it does increase the output across the entire spectrum, but mostly above 18 MHz, and it is greatest at 28 MHz . It cancels some inductance at higher frequencies that is problematic. I see a
