I personally prefer a max of ~10W also (battery power, etc) and the RD transistors are definitely intended for "RF" use and work great on 10m/15m (vs the 510s which essentially quit around 18MHz). I was wondering if anyone has tried the RD06HHF1 RF transistors ?

My first unit arrived in Eastern NC [first week of Feb] on the 4th day after I received the DHL shipping notification.  No customs fees or other issues.
Now waiting on the three I ordered in late February...

That is apparently NOT the case with DHL for US purchasers.  My 3 cleared customs and were delivered by DHL couriers with absolutely NO extra charges.

Subject: [BITX20] US Purchasers of the µBITX

I have had mixed results purchasing some items from the UK & it appears from their website (hfsignals.com) there have been some issues with units shipped via DHL to the EU. I am looking for feedback from this company as how things went for you. The company website also seems to indicate there are additional customs charges if DHL is used.

Sorry but the budget is not what it once was.

If you really want to know, test the part with an multi-meter on the "diode" setting. That will resolve the polarity for sure.

DHL shipped without any hitches. From India to NW Pennsylvania within 3 days. No custom fees.

I have been programming Arduinos and other small microcontrollers for some years. I don't see the benefit of using a web-based IDE/Editor/uploader. The browser just adds another layer of potential instability.

Web-based tools make sense for functions that are otherwise expensive or difficult to install. For example, ilovepdf.com is a nice set of utilities and hard to duplicate in an installed app.

I use the standard Arduino IDE (free and reasonalble to install) and have had only minor problems over the years. One common goof is using a USB cable that is not designed for data.

It would be interesting to challenge the trademark as Lockheed has allowed it to fall into general use. Many companies and people use the term to illustrate a type of behavior and not to refer to Lockheed. Just as it would be interesting to see if the Google trademark would hold up as they have let it become a verb. Trademarks must be defended or they can fall. Also, I believe, in the US first in commerce and not first to register establishes trademark. Yes, one can have two of the same names if they exist in two separate industries, especially if the individuals are not in the others’ industry. Of course, what do I know.

Well things picked up nicely this evening, had confirmed qso's with KN4AIE Rick in TN, N6ORS Keith in WI, N8DLP Kevin in OH, AC9PD Larry in WI, W1LY Willy in RI, WA2FZW John in MA and WI1B Ken in Ma. Congratulations to a couple of 1st time uBITXer's. Some great sounding, some at the noise level and some light audio. Conditions were a heck of a lot better today than in the past months. Keep working them BITX's. So far the BITX40 is proving to be a solid monoband rig.

A close friend of mine has a software company that he originally called Skunkworks Software.

After a few phones calls from a few lawyers he thought it was in his best interest to change the name to SkunkWare.  At that point, everyone was happy.

John,
You are right about the, Si5531. The way it panned out was that first there was the. Bitx40 with analog vfo. That was unstable for the digital modes, so we made the raduino. Then, because there was a raduino, the ubitx happened. 
Designing radios teaches you how to design them. Neither of the two radios was supposed to be all that they are doing now. This is purely the effort of you guys. Very often while searching for something on the net, the most relevant information is from people who have done something extraordinary with these radios. I continue my education.

Dear Mr Farhan, 

Thank you for your post. I also personally think that 10 watts is is a good number and I have set my rig at just under that on 15 to 10M.

Unfortunately to get to this  power level, the lower bands have to be above.

In my case that value is 16 to 17W on 80M. sloping to 9W on 15m and flat after that despite the mods that have been described in this thread (its original objective) and in other threads. The original variation as-built was, from memory, 10 to 1W variation across 40-10M, or 17 to 2W at higher PA voltage.

I am working on an 1st If shift based ALC/power limiter using the technique described in my other post and this will hopefully allow for a completely flat power curve over the bands.

But unfortunately this is expected to only work in SSB modes.

So the issue remains that the power curve as designed is quite steep.

My wish for a future version of the uBitx is, if there is one, and I sincerely hope there is, for a somewhat flatter curve. A maximum variation of 1 to 2 for example would be in my opinion quite acceptable.

While we are on the wishes, it would have made my modifications much simpler if the Si5351 was on the main board as it would allow to extend the I2C bus to whatever micro-controller we wished to use.

Finally, a big thank you for such a wonderful rig. It is such a pleasure to work with, and its customisation makes it an unparalleled match for our own needs.

All the best,

73, John (VK2ETA)

Actually, I do not 'receive' my post twice.  My email client puts a copy of all my sent emails in the appropriate folder.  And then I receive the same from Bitx20

Sorry for the bandwidth.

Congratulations Rob.
My first HF rig was my BITX40.  I never bought into the don't start with QRP argument.  I think it is aimed at the instant gratification types that would give up if they didn't make a 59 QSO with some obscure DX station the first time they hit the PTT.
