- I've replaced the carrier null pot and was able to finish all of the alignments. Now, let's take some measurements of just how well the receiver and transmitter are working - do they meet the Heathkit specifications?

Awesome Video , Im Restoring one myself, its working good but , no ALC meter... love your show !
Great video series, I own a HW 101 for a long time, I will have to one day go thru it. Works great but owned for 40 yrs
Thanks for the great information on restoring the HW101.
Loved the series. Real nostalgia. Very good de K0WA
Definitely enjoying! Look forward to the final review. 73 - Dino KLØS
Been enjoying from the start..
Really enjoyed the video. I have just built an SSB tube transceiver for 80/40/20.
Great job Darren! Totally a different rig…..A simple enhancement I did for my HW-101 was I took and colored the dial lamps with green glass dye. It gave the meter and dial a green glow. Take Care and thanks for sharing the videos! Larry W4PJP
Great tip, thanks for sharing!
FYI If you have a compressor, you can get a cheap hand help sand blaster gun at Harbor Freight for ~ $25. maybe less. The media you should use is the soda, Sodium Bicarbonate. It's more expensive but if you keep it dry it will last for years and will clean those panels QUICKLY. . Next, buy a can or two of Zinc Chromate on ebay. It's still used for aviation and marine apps. Buy a spray handle which fits on top of spray cans. Zn Cr tends to be heavy and if you use your finger tip on the nozzle, it will bind between the nozzle face and your finger tip and splatter all over your work. START OVER TIME, YUCK !!! Been there done that.
Next, take one of your HW 101 panels to a Sherwin Williams store and have them use their spectrometer to make a small amount of the exact color. You will need an automotive quality sprayer, also a cheap one can be had at HF.
To get the texture effect that Heath uses, thin your paint about 60%-40% paint to thinner. Get some cardboard boxes and play with your sprayer until you get that effect by decreasing the air flow and increasing the paint flow until you get it to just to start creating the texture look; TAKES PRACTICE. However, with a little work your results will be better than Heath ever did and you will be proud of your unit for years to come.
Of course, do this all outside on a warm dry day, You may want 3 - 5 coats of paint or until the coat is thick enough. Sun drying will speed up the curing process or if the wife is away, the oven at the lowest setting for a few hours will mostly cure the paint.
I did an article for Electric Radio Magazine to show how to properly do R390A front panels. If you have that magazine, let me know and I'll look up what edition that was. If you want a copy and don't have ER, send me an email and I'll make a copy and send it back to you. Lots more detail there than here.

Glenn, thanks for these very detailed tips!
Great videos! I considered buying a monitor to go with my sb101, but I have a kenwood station monitor and its a pain to use. Especially as a bench scope. Id rather use my Tek 465 scope and take advantage of the trigger. The monitors are neat though!
Very enjoyable series. Looking forward to the next installment.

My spectrum analyser goes from 10kHz to 140GHz with a dynamic range from +30dBm to -100dBm. Yes it’s a pro instrument.
Buenos dias desde España. Querria saber como conectar un frecuencimetro. Para saber la frecuencia exacta de tx y de rx. Gracias por sus videos
