I have been using my Winkeyer USB with ubitx and it works fine.

Are they 8.5 amp or 2.5 amp? Everyone I have seen for sale are 2.5 amps

I bought an original SW40 kit about two months ago, and it's sitting on the shelf staring at me. As soon as the JackAl project is done, that's the first thing I'm going to build. And thanks for the BD

Please sign me up for 1 each. 73, Dennis W7DRW

Jack, couldn't agree more about building your own stuff and CW. Just finished a small wonder labs sw40 (Midway electronics version) and its been getting way more airtime than my appliance rig. And

Thanks, Craig. I wish there were some magic wand I could wave to make all hams experience the enjoyment that comes from building and operating your own "stuff", whatever that might be. Same for CW. I

Hi Rich: Yep, books is correct. In fact, 18 books altogether and working on #19. You're kinda an old-timer like me. I got my first license in 1954 and upgraded to General a year later. Been licensed

Let your clients, namely us, pay the full cost of shipping. Just like the good old days. - Rich WB2GXM

Ken, Thanks, I enjoy helping out a little where I can. Too bad the EU doesn't have those "ham friendly" customs notations. I just had a guy tell me he had to pay $30 VAT for some kits.....bummer. I

Something is mighty fishy. Or the input frequency for the VFO as set should 3.915mhz. 48.915mhz -45.000= 3.915mhz Try raising the signal generator from 3.8mumble to 3.915 and see if things get better.

Kees This is fantastic. Thank you for your work. For Canadians who order, marked package as "Amateur Radio Kit" or something like that. No custom fees will be charged and helps expedite the order

The 45mhz filter is rather narrow If memory serves its a 15khz (wide) unit which is typical for common use (FM first IF work).? ?So for low attenuation you need to be between 44.9925 to about

A list of potential orders as of 5/3/2018 at 7:30 PM local time has been uploaded to the FILES section under my call? K5BCQ. The total is surprisingly high (250+) for just starting out, but very

That's interesting I ordered two cases on 4/14 and still haven't got mine! Roy WA0YMH

All, My ubitx has quit working in receive and SSB transmit. CW transmit still works. Attached are spectrum analyzer traces at C216 and C210, i.e. the input and the output of the 45Mhz crystal filter.

I order mine on 4/15 and received 10 days later via DHL. I received shipping notice from PayPal and was able to track all the way. 4/15 was when they received the new stock and I ordered one they had

Oh, don't even go there. I have your book also, by the way. Isn't that "books?" I believe I have two of your books. Don't shoot me if I am thinking of somebody else... ...I too am a "paper" person!

To return to the original suggestion of using 25MHz IF, I built a version of the Minima using these Fox FOXLF250F-20 25MHz crystals from RS Components au.rs-online.com part number 5476121 The idea was

See this post: http://ubitx.net/?s=Top+band It works you just need a low pass filter. I found it draws more current so make sure you have a good heatsink or fan to keep the finals cool.

I was playing with the uBitx I just completed and noticed that it will TX on 160 meters. Is the reason it is not used on 160 the filtering? I seem to remember a post or something showing a filter to
