SolderSmoke Patreon — What We Will Do with the Money


I mentioned our Patreon fund-raising effort in Podcast #223. We immediately got a number of new sponsors. Thanks! We also got a question: “Hey Bill, what are you going to do with all that money?” In the spirit of SolderSmoke full transparency, I will attempt to answer that inquiry right here and now:

All funds will be used at the discretion of SolderSmoke management.

Possible (likely) uses include:

— Buying air time on shortwave broadcast stations so that the SolderSmoke podcast can be transmitted over the airwaves. We dream of stealing listeners from Brother Stair.

— Computers. From time to time we need to upgrade. This 486 machine is getting kind of rickety.

— Paying fees to our internet service providers and to the server that hosts our podcast.

— Contributing to worthy charitable causes, including the Color Burst Liberation Army (CBLA), and the Constructor Crusaders.

— Buying audio gear we use in the podcast like the really cool microphones that have DRAMATICALLY improved our audio. No more baby-wipe pop filters for us!

— Legal fees to the law firm of Dewey, Cheatam and Howe to fend off law suits, many of which are related to our obstinate use of 60/40 solder, and to our occasional use of images that SOME PEOPLE find offensive. We also need to pay legal fees to fight our long-contemplated expulsions from the QRP Hall of Fame (Pete is especially vulnerable here).

— Magazine subscriptions (to those few remaining publications that have not pissed us off ).

— Buying stuff we use in video production (cameras, tripods, lights etc.)

— Further development of the SolderSmoke 401k Retirement fund. We currently invest in Drake 2-Bs, SSDRA books, Hallicrafters S-38Es, 3579 kc crystals, and other items sure to rise in value over time.

— Buying gear we will talk about on the podcast or in videos (like the NanoVNA).

— Parts. Si5351s and Raspberry Pi’s for Pete. 2N3904s and J-310s for Bill.
— A new effort to assist electronics manufacturers in China with product name selection. “Mean Well” is just not a good name for a voltage regulator. And “FeelTech” does not bring to mind a signal generator. For a fee, we can help!

— Travel. If this ever becomes possible again, we need to get to India to meet up with Farhan. This will undoubtedly result in some awesome podcast/blog/video material. We also contemplate trips to the UK, Italy, Australia, China and New Zealand. But we still probably won’t go to Dayton.

— Buying miscellaneous tools, test gear, books, solder, rosin etc. to be used in the podcast, the blog, and in video production.

— Buying stuff for carefully selected new homebrewers (people who will not sell the stuff we give them and then use the money to buy Baofengs).

— A new Baofeng buy-back program. You know, like for assault rifles, but for VHF/UHF walkie-talkies instead.

We seek your input! What else should we do with the money?

QUARANTINE PROJECT: Q-31 AM SW Receiver. April 4 through April 19. 15 days of fun. Learned a lot.
Need to pay attention to total gain. Need to measure. Not always easy. My resistor-based technique.
AM detection can be more difficult than SSB/CW detection. Germanium diodes make a big difference.
But…I don’t have to build a BFO, because these signals bring their own beat frequency.
455 CAN BE PROBLEMATIC AS AN IF – image response, making impedance matching transformers tough at those low frequencies. But WIDE filters available.
LM386 AF chip make a LOT of audio. Hard to reproduce these great results.
Great stuff you can listen to on 31 meters (9.4 –10 MHz):
n DX WaveScan
n WRMI Rock and roll
n VORW music show
n Radio Nacional De Espana (Madrid)

Anonymous mail: FT-8 DX — Are these contacts legitimate? See below.

Dear Bill and Pete:
I’ve been meaning to share with you something that has come to my attention by a rather circuitous route.
As you guys know, I’ve been involved in the software/IT side of ham radio for many years. I’ve watched many digital modes come and go. I’ve always enjoyed my work, but lately I’ve seen something that makes me uneasy.
I’m sure you guys have heard of the fantastic DX that is being worked by many guys using FT-8. It seems like all they need to work Jakarta is a couple of watts to a wet noodle. Shazam! Contact!
Well, I learned something that calls into some question the legitimacy of many of these contacts….
As i understand it, certain manufacturers, in cahoots with a major American ham radio organization (that happens to be very dependent on ad revenue from that manufacturer), have secretly set up a system that combines the internet and ham radio.
Here is how it works: Suppose Joe Ham gets on FT-8 on 40 meters. He puts out a call using his QRP transmitter and the aforementioned wet noodle. No way that signal is going to Jakarta, right? Well, it will with a bit of help.
The system has SDR transceivers and great antennas set up at strategic points around the world — these are really great locations — think mountain tops near the coastlines, always with high speed internet T5 connections. I think this is part of the whole “contest superstation for on-line lease” business model.
One of these stations picks up Joe Ham’s FT-8 call. Sometimes it will just re-transmit it, sometimes is will send it to a counterpart station on the other side of the globe. Bingo, Joe Ham’s signal is suddenly in Jakarta. A station there enthusiastically responds, and that signal goes back with the same kind of repeater/ internet assist. This is all done out of the reach of the FCC. They are usig overseas locations, some of them in Mexico.
Of course they have to be careful not to “facilitate” these kinds of contacts during times in which the bands are obviously dead, That’s why 40 is so useful for this system. Obviously they can’t keep this kind of thing secret forever — they just want to get guys hooked on FT-8, then they can reveal the system, selling it as nothing unusual, you know, sort of akin to Echolink.
Of course, this hasn’t been made public (for obvious reasons!) but I can tell you the name of the system: They tried to make it sound like something familiar (in this case like APRS): They call it “Automatic Private Radio Internet Link 1.” My understanding is that when they do their “roll out” they will offer the new service to those willing to pay a subscription.
Obviously as an old-school, traditional ham, I’m troubled by all this. What do you guys think? I wonder what your listeners would think.
Please don’t mention my name.. But here is a site that describes the new system:
Thanks and 73…
Please let us know if you have any information on this, or have observed any unusual and suspicious success with FT-8.

Hi-Per-Mite from 4 State QRP. Easy to do. Works well.
uBITX to 5 W level.

S-38E adventure.
Replaced antenna input coil BUT — it came from an earlier S-38 and doesn’t resonate.
So I bought a junker on e-bay and will take the E model coil out of that one.
Had to re-string the dial! And add rosin to it from Maria’s old violin.
BFO was not working. Bad buzz sound.
So: Re-cap, Re-tube, Re-string, Re-align, Re-build power supply.
Shortwave sounds good. Nice to hear music coming from our machines.

Bill’s Bench Report

Following up on proposed uBITX mods:
— Put pot on sidetone line from Raduino to keep the sidetone a bit quieter.
— Fixed the key — pounding brass
— Will install 4 States QRP Active AF filter.
— Need to reduce power on CW to 5W
— Stereo to mono headphone adapters.
— Turning off display and mic amp circuit not really worth it — they don’t pull much current.

Got idea for wider ceramic filter from Paul VK3HN
Ordered parts from Mini-kits in Australia. They sent 6kc filters.
Bruce KK0S sent me some 10 kc filters too.
Installed 6 kc filter with L network matching networks. Works great.
Also installed Infinite Impedance Detector that Paul used.
Needed some additional amplification ahead of the IID, so I used one stage of BITX amp.
Works great. I can tune full 40 meter band AND 49 meter SW band. Radio Romania, China, Radio Marti, Brazil, South Carolina.
Beefed up the shielding to cut down on AM detection.

— Using Reverse Beacon Network
— How to keep receiver on the right frequency
— N0WVA’s receiver sounded better, so I built a second N0WVA receiver
— Regens reach back to Edwin Howard Armstrong’s 1912-1923 breakthrough

Simplicity is the real reason for CW

IDEA: Get those Michigan Might Mites on the air!
Use Reverse Beacon Network to see if you are getting out
Use SDR receivers to make contacts
