Great video! I know this video is 12 years old. Do you still use your PFR-3?

I bought one for my son 2644 rpm, 220 degrees Fahrenheit measured with an infrared temp gun at the sight glass end of the boiler, at full steam. We both love running it, the little guy is a huge rail fan. Awesome creations!!

I found a Type 70 at an antique store! Ordered a safety valve and steam oil! Beautiful machinery!

Nice demo

Nice review, 73's

Very nice.

My step dad complained that he never had one as a child, so I gave him one late in his life. He ran it once for his step grand daughters but they showed no interest.

Any updates to your collection?

Interesting.

Very helpful, Roberto. I have just ordered the Grandson of Zero Beat and am looking forward to building and using. Would like to know what the red button is for and how it is used, as well as how you hook it up to your radio (I presume and audio-out port?). Many thanks for posting! 73

Like old radios, I can still repair them, I like the green eye snake tuner. I can also remember WW2 war, we had a Zenith radio but being so young, I could not remember specific radio broadcasts. great radio hobby. nice job.

Qué belleza, Roberto. Enhorabuena por haberlo devuelto a la vida. 73,

0.22 em wilesco and i think jensons just coped wilesco and wilesco is buitiful it is the largest steam company ever

Nice video !

Excelente , empece muy joven en la radio y tenia una estación muy similar.

tengo en restauracion final un hro5ta1 del año 1945/46 en estado original con su casilla de perro y speaker de national y lo poco que escuchado es una delicia su sintonia.

Nice video of shop! I had the opportunity with Mr Jenson for many years and heard a few stories of the steam engines. Its time for me to get one of these...

Beautiful HRO! I have several HROs and they are true classics!

Hi Roberto! Great job, congratulations. I have a HRO, too, I think the same one you have. Great radio. In fact, once you have a HRO, you can clear out all other stuff. You won't hear more than the HRO will give you. But that is not who we are, LOL - Regards, Henk - Parasetguy

ove that M65 , I am in the process of buying one so your vid was useful and I subscribed 251

Beautiful.

did you ever get anywhere with your ALC backwards? I have a similar issue with my 32s-3...73 ag6if

Great restoration and description.

Nice old Jensen!

Stop press Roberto.. there is a qrp Power amp Kit $30 USD sold by Diz the toroid man in Florida that provides 5 W out (but it can clearly provide 10W by comparison with his now no longer sold 10W linear design) it provides Silicon RF switching which is Definitely what you want for CW. It provides all the outputs for SWR indication .. you provide the meter. What it does not give you is a matching unit. You could at very simplest build your own L- match matching unit for realistically $8USD of components and a whole lot less if you can find a polyvarcon (200pf old transistor tuning capacitor) from a scrapped transistor radio. In order to get the 10 W out you would need to add some bias on the final PA transistors. This is a whole lot technically safer than building up the Mosefet amp and then having to bolt on all the extras to get it working. NB DIZ does not sell the low pass filter parts to go with the kit. You have to select those yourself. Motorola AN 297 and a bit of RF knowledge is all you need for this. Obviously you have to find the right tapping points to get the signal in (RX) and out . YOU Cannot have the three MOSFETS in the PFR running simult UNLESS you dump almost all of the power into a matching resistor set .. so you need to think about having a PA on/OFF switch on the PFR for this use. It is extremely unlikely that the PFR is running more than 3.3W to 3.4 True watts out. Why .. because it is common knowledge that if you run a BS170 above about 1.2 W in class C it will generally not last long. [the current Qrx kit for example is sold on their site as 5W yet the very golden build example specs show 4.0 W out . Some real builds get only 2 W out]. If your true output is 3.3 W then 10 W out would give your signal about 5dB more punch (just under). You can contact me on Engstr AT ..... Netspace Dot Net.au if you want further information- I have worked with other RF before but not the PFR design though it is very clear to me. I have had luck with getting parts shipped from A to B in the USA then B adds his parts and ships the whole lot out. It saves a whole lot on postage and many small vendors are willing to do it... cheers TEF.

By the way Roberto - talking of STEVE Weber designs, Fred at Far circuits has the 75 mtr board for the Weber SSB transmitter , board only. The parts are not too hard to get though in Sth or Central america that might not be the case ..the 10.7 Mhz IF cans can only be had from "Cecil the parts place" in the US and one place in south Australia . The mafr has stopped production which is a real shame... Steve W inidcated to me that there was no problem putting it on 40m with tuned circuit recalc. There are several DDS vfo kits around that will work with it including a bind VFO from Crkits.com in PR china. for $20 USD plus postage. The Vfo or PTO that Weber talks about is bit too much mech engineering when you look at it. ... Prematched filter crystals for a ten Meg IF can be had from Leon at ozQrp.com in Australia if you talk nicely to him for around $12 for a set of three IF crystal and two others for LOsc and Carrier Injection Osc.; you need total five off. Just an idea.

Good video om , you explained things very nicely de ka3fad

I just love this kind of stuff. Congratulations on 'doing ham' the right way. I have not built anything from scratch in a long time but I do buy old broken radios and repair them. My current radio is a Yaesu FT-757GX off eBay that was a real basket case and a Yaesu FC-757AT that I had to repair also loading up about 90 feet of gutter at 25 feet (I own a condo and absolutely no antennas are permitted... fooled them). Would love to make a contact with you. W8DKM

Bought one! Initially bought a Wilesco but felt tinny and cheap. Also the whistle had defective threads. Sent it straight back to dealer paid an extra 50 pounds and got a 75. Paint aside it is in a different league to the Wilesco in terms of strength. The consensus on the toy steam forums is that Wilesco have dropped in quality and have niggarly cost cutting: plastic valves and wheels on their steam trucks. I have some British Mamods which are tough little things but the 75 is tougher.

I want to get the model 75, what do you guys think

Oh well I might buy one lol. I would like to deal with them direct as they seem a nice crew. It depends on shipping charges from US to UK though. They are notoriously high.

Nice engines but I was speaking to the guy in my hobby store in the UK and he recommended Wilesco over the Jensen as they use bad quality paint on the burner which blackens and peels off after first firing and looks awful. It's a shame. Apparently he rang Jensen to raise this with them and they were pretty offhand with him.

Yes I will and thank you for your response

I just found my model 65 on top of the beam in the basement and it still works

WooW Good You Rock Man ;)

Tengo un manipulador igual que el que muestras, pero el mio conserva la base de caucho fundido, con unas formas en pirámide invertida de cuatro caras que sirven para que el aparato no se deslice durante la operación de transmitir. Saludos. EA4TO -Paco-.

There was the US Navy version and the German flameproof key. Both are excellent, but, I will have to give it to the Germans for making theirs more substantial. sites.google.com/site/telegraphkeys/Home/flame-proof-wwii-keys

I just bought a model 60 at an estate sale for $5. Nobody there knew what it was, all they saw was some old piece of junk. But I knew. It was missing the whistle and fuel tray but I was delighted to learn the parts are available from the very company that made the thing. Astounding to see an old-fashioned industrial factory still in business doing the same thing they always have. The Jensen operation should be a national treasure.

Hi Roberto....very nice demonstration and I like the way you combined the filter with the zero beat circuit. Would you happen to have a picture of the inside? Thank you es best 72 de wa4chq

Great Job. I have a no-name J-38, probably ARH with a Signal Corps stamp on the plastic base. The contacts are narrow(~1/16") and have a black coating on the circumference. I wonder if they are silver since the contact surfaces are white. My dad bought this for me at a thrift shop in the early '60s for $1.00! Unfortunately a lot of the various military keys in your collection are getting harder to find and a lot more expensive. Several years ago I bought three different Nye-Viking Speed-X keys. Glad I did since they are no longer in full production. I enjoy your videos, they are very informative.

+Robertosala1 *Telegraph sounders were manufactured with position-specific coils* for local, relay, and main-line service. The 5Ω sounder is a local model, built to run on not more than 3 VDC; 1.5VDC is conservative. The Vail Code is an early use of pulse-width modulation: The key-on time for a given dot duration could be 1, 2, 4 (the Lima long dash), or 5 (the Zero long dash) dots; the key-off time, 1, 2 (inter-element for specific letters), 3 (between characters), or 5 (between words) dots.

Nice. I can't seem to find one in good condition on ebay. I was too late.

Tento key je ten nejlepší, který jsem měl v ruce. Starší, armádní kus české výroby, ale lepší neznám!!! Petr, EX OK2-30658.

It is s superb key and it may well be the best that is still in production.

Excellent. I just picked up a J-38 at a hamfest this summer and I wish I had it 40 years ago when I got started in ham radio! I used a Radio Shack "look-alike" straight key that worked fine for years but the J-38 sure feels better.

The magnetic field of the direct shaft generator allows the steam engine to stop in a position where it will usually restart without help. Very nice.

Dad's old blacksmith shop still has all the old line drive shafts where it ran a trip hammer, drill press, pedestal grinder and lathe. It didn't use steam but it has the original DC motor that ran it. Forgot about the non working DC ceiling fan that the shaft drive ran above the coal forge. Seeing this setup reminds me of when I was a kid and working plow lathes and hearing the shaft running above me. Thanks for the video.

I bought the RM-31 at the Shreveport, LA. Hamfest8/13/16. Thank you for providing the history of this key. 73 WB5OSD, Bobby

I had a buddy in the 8th. grade, Ca. 1952, he had one that I thought was powered by alcohol .....oh how envious I was.
