Nice thread!  Motivating. 

Our local club build of v4 ubitx delayed a host of projects - so just getting back.  It was nifty to hang out with more than 2 dozen builders, many who had never built a rig before.  Of course the v4 needs a lot of care - mods for spurs etc.  Mine has a nifty AGC made from an LED and a photoresistor that works amazing (and makes light!). 

Just a couple days ago replaced a volume pot on a cheap reproduction AM/FM radio.  Why do I mention this?  A lot of disassembly to get to it.  Board with a few cheap parts on it buried inside -- wow the sound of a big speaker in a wood cabinet - this thing sounds great (the original pot was always bad). 

Built a QCX+ and companion PA for 80m -- very nice rig and the new version is easier with larger part spacing. 

Put up the short 250+ foot Beverage that just fits in my yard - at times it is amazing, and often gentler on the ears. 

Turned on my WBR regen for 40m - this thing is amazing even though it does not look like much.  I can copy CW signals well enough to QSO with it.  One of a few regens homebrewed -- maybe someday I can graduate to superhets - I have a HYCAS and a few other modules sitting on a breadboard -- and I need to finish assembly of the now-obsolete PHSNA that is mostly assembled. 

I am fixing a variable voltage power supply built from QST nearly 40 years ago - it never would reach above 9 volts so maybe a bad lm317 we will see. 

Have some stuff gathered for a tube Tx to 'replace' the xtal controlled tuna-tin+mosfet I used with my first receiver. 

enjoy your efforts.

Hello all,
Well, I have several Eddystone receivers, now all in fine working order. Bar one where the tuning mechanism seems to be jammed! Ah well, now that South Australia is back into lockdown, we'll maybe get a roundtoit!

Dang, those where the days... open chassis with upwards of 430VDC floating around; seems insane now, but back then it was SOP.
I remember the spark gap stuff my Uncle had. Rotary SG throwing around 1000V out in the open; Oh Yah! (Edit - No I'm not that old, but I saw old photos - but can you imagine how cool (and dangerous that was!)

I am currently playing with an Arduino solution to my dehumidifiers bad mother board. In development stage at this point.
So far I have the Arduino reading a DHT11 and displaying the results. The rest shouldn't be too hard.

If anyone wants to see my Philmore NT-200 Novice Transmitter clone, go to the following web sit and scroll down to the bottom and click on "w0vt's Philmore transmitter." It's called a Philmore NT-200 Deluxe.

Lee,

What a great job ... times three - you're already in serial production!

For anyone who's interested in the original Philmore NT-200 kit manual to see how accurate Lee's replica is, which is well worth the look back into The World That Time Forgot, here's a couple of links to the PDF of the same scan of the manual (redundancy is the enemy of BitRot!):

Hi Lee,
You certainly did a great job in constructing your clone of the Philmore Xmtr and power supply. You could probably make some good part time money offering for sale the following options for the Philmore.
1. A bare, undrilled chassis. 2. A bare, drilled chassis. 3. A bare, drilled, painted chassis. 4. A complete kit, with drilled, painted chassis, and all parts.
I believe there is a market out there that might be sufficient to make it worthwhile. I know someone did exactly that for the popular Ameco AC-1, 6V6 Xmtr. The Philmore design is superior to the AC-1. You might even consider such options as above, with the AC-1, as a clone.

Another vote for the WESD51. Mine "just works".

Hey Lee,

I became an amateur in the late 70’s and missed the tube era. But you are an artist in construction!

What's on the bench?  Too much! hihihi

The N75 is at the operating position providing music and the necessary sounds of the atmosphere as she dances the night away.

There's a new V6.2 µBITX on the bench in the early stages of being supplemented and boxed.  Well, it's spending more time under the bench because there's a KX4Z digital mode interface board in process*.  I'm installing the 7 dB pad* in my somewhat experienced WA2EBY amp to play nicely with the µBITX when it's ready.  There's a W0EB raduino clone board (moving from arduino to Teensy 4.0) in progress.  A bit farther down the list, I'm waiting for my first 'operational' board from OshPark.  I think I finally figured out how to go from schematic to board with KiCad.  If it works, the small SMD ILER40 Mk2 mic preamp board will be part of the µBITX project.  (* Waiting on a CARE package from Mouser)  There's also a 12/24V LiFePO4 battery box in the early stages that'll run both the radio and WA2EBY amp.

To stay under the bench until I again feel like playing with 14 AWG magnet wire is the hybrid DJ0ABR/W6PQL 1500W amplifier project...and the associated power supply project.

Thirded or fourth'd for the Weller WES51!

Has anyone seen the Mouser bag of 0805 4K7 resistors?  It's around here somewhere...  hihihi

Hi,
  I would also recommend the Weller WES50 or WES51 temp controlled solder station. Many tips are available. We used these and earlier Wellers in the electronics repair shop I worked in. I like them because they are reliable and the pencil assemblies are slim!
