Interesting. At the time I answered Bear's post earlier today, the site did not respond. But now it is responding. At that time I verified DNS was not the problem. nslookup bunkerofdoom.com Server: UnKnown Address: 192.168.0.1 Name: bunkerofdoom.com Address: 206.130.102.170 Whatever it was, it is working fine now. There was no ping response at 21:06 EDT today. Go figure..... |

I'm able to access the site, but many of the links to manuals and such just lead to the dreaded 404. Not all of them, though; some of the links work fine.

Uh-oh.
Just went to see if Bunker of Doom had a manual... looks like it is down, unpaid, or something??
Anyone know what happened?
Trying to pull his name out, swapped emails some years back... he had a LOT of STUFF!!

Bear, try sending a PM or email to Patrick, KD5OEI. His email is listed on the zed. |

Thank you Phil,
WE have bad experience with NOS tubes not functioning according to specs and not living very long.
The 1642SE trafo can be bought brand new e.g. Mouser.com sells them.
Also the 6146B tubes can be bougt brand new. They are Chinees and so far they do there job all right.
The power you mention is right. We experianced max 50 watts rms in the antenne with 475V anode power supply and even more than 75 watts with 625V power supply.

One thing I found amusing: walking around inside the building, a couple—probably husband and wife—passed by, and I heard the guy say, "This is a waste of time. Just a bunch of ham radio junk in here!"
It puzzled me, but then later on I figured that they were probably part of the horsey crowd from the other side of the fairgrounds, who wandered over figuring they'd find some horse liniment or de-worming pills.

Thank you William & Phil, You are a great help :-)
We are considering the 1642 now althouw it is a lot of Iron and a bit expensive.
And we forget about the idea of increasing the voltage.
Yes the transmitter is legal with a licence and we may go to max 100W PEP.
The frequency is 1395 kHz and the antenne is a 5 meter vertical with a huge capacitive hat.
The pi filter calculations we apply look verry much the same as yours Phil.
Last doubt.
We will try Screenmodulation too. But not with a 6DE7 as used in the Heathkit DX-60 because we do'nt like NOS tubes.
Does someone has a schematic wiht tubes that are still produces these days? I don't know what you mean by not wanting NOS tubes. What is a 1642? Calculations show that with two 6146's in parallel, SGM, you should be able obtain at least a resting 50W carrier. According to current mythology, that equates to 200W PEP at about 100% modulation. I think you asked for a SGM schematic, so here is what I use. Phil AC0OB |

I posted this over on QRZ also. I didn't learn about this until today. I knew Phil for a good many years. He could be overbearing, pompous and very technical. One of his favorite activities was pi$$ing off his neighbors in West Creek, NJ during Christmas time by having a 'Santa Claus' crawling out of a toilet!  When he first moved to Shickshinny, he would operate one of 2 Collins 20Vs or a Gates BC-1T from his house in Wolf Creek remotely. I helped him move a Collins 21E along with the ATU and Phasors during a thunderstorm at his home in Shickshinny. He eventually got it on the air and would command a big presence on 1885. When I talked to him this past December, he told me that he had suffered some antenna damage with his Unipole and would need it repaired before the 21E could return. In the meantime, he was doing CW on the other bands. He was 70 years old! https://www.gosselinfuneralhome.com/obituary/Philip-GalassoWow, what a shocker! Have not talked to Phil in many years but we chatted often some years back. He was a regular at Frank's - KB3AE (SK) post Timoniun parties. |

Yes, that label alone was almost worth the purchase price, whatever that might have been. 45KV vacuum variables! One can only wonder what the new catalog price of those babies must have been!
No, I didn't buy it but I met the guy later who did. He had to disassemble it. Apparently those who came with him had his car stuffed with so many things that he had to disassemble it to fit inside his car! I asked Ed about the voltage rating on those caps. He said they were rated at 45KV! I did like the label on the front: "DO NOT EXCEED 5KW"!
