Practical troubleshooting, board-level repair and micro-soldering of amateur radio handhelds, mobile radios, building electronic kits and other projects. This channel is really geared towards the beginner who would like to learn how to repair their own equipment and build electronic kits and projects.
Thanks It works. I brought the new battery from Amazon for my 1st Generation ring doorbell. Which is no longer supported by ring. However the battery won’t stay in place. I discovered my old battery had died because either corrosion or something wet hit the slots while taking it apart to replace it with the new one. After wiping the old one off with alcohol and a q-tip the old one worked again😂. However 😅that won’t snap back in either. So my problem is 😢neither battery will stay put inside the ring camera bec whatever piece to hold it broke I guess?

what a great resource, thanks.... I suddenly find myself dealing with some serious RFI wiping out the HF bands from about 7 - 20 MHz and I found the prospect of addressing it to be so daunting I didn't know where to begin. This gives me hope - thanks de AB1DQ.
Thankyou for providing this tutorial. Excellent presentation, information & methodology, pitched right at my level of understanding. I will try as many of your solutions as practical within my budget and location limitations...That will certainly keep me busy and away from the pub, which in turn will increase the budget for the more costly solutions 🙂. I have subscribed to your channel and hope you continue to produce more high quality videos like this. 73 2E0IOL.
I had 4 messages posted here from the past 3 years. I decided to delete and repost as 1. This remains the only YT video about building the Tetrode Board set and remains a valuable video. I've got about 4 years into this project myself and I'm still tinkering with adjustments. It's a lot of material to master and building an amp from AC plug to antenna is no small feat. At least 5 different power supplies are needed likely more. These boards are out of production by G3SEK but available by another organization that appears to have G3SEK's blessing. I suspect the customer support / Tech questions became too much for any one person. The original Manual by G3SEK is as good as it could possibly be. The problem is that the options are infinite. No Tech-Author can anticipate what other Builders would encounter. Need to know or learn enough to complete your own plans. Support beyond the manual is next to nil. As replacement control boards to an existing Tetrode Amp yes, a perfect solution. Still it's not a theory-free install. I will communicate with anyone building these boards to share what I learned and hopefully learn more from someone else. I find it odd that after thousands of these Boards being sold, there is so little posted online. My online search results can be counted on the 1 hand of an old fisherman (who frequently lose fingers). I'm still tweaking and troubleshooting but making progress. I built around an old Eldice RF deck/blower box combo designed for two 4cx300 tubes (now, it's grid-driven, grounded Cathode, 10-80m). Made everything else (occasional pics Worldwidedx.com). Being multi-band makes it mechanically complex even with a Roller. Again, I want to thank KA6WKE for posting these videos despite his aborted outcome. This series is the only build vid about these boards and shows it's not a piece of cake. n2eye
Thanks Mark. Mine died all od a sudden after I hardwired it and it did work for many months. Now the unit is dead. I'll take it apart and check the battery
What I don’t understand is my noise is around a Five level or four sometimes I shut the power in my house. It did not change. I took the car for a drive around the neighborhood. It did not change. At night as soon as the sun goes down, it gets horrendous could barely talk to my friends on side band 20 miles away. I’m going to try the QRM box eliminator. First I have to have a PTT jack put in the back of my quad five and I take it step at a time. I guess my house is old and doesn’t make two many problems with electric? I believe mine is all atmospheric.
I don’t understand your demo. It sounded better with the unit off. So what is the purpose? A better demo would have had a signal that you had trouble hearing without the unit on, and then by tweaking it, you dig the desired signal out of the noise. You’ve done just the opposite! 😂
Thanks for the great tutorial, just installed my replacement battery and as you said; hopefully get a few more years out of it. Thanks for sharing your knowledge with us.
I know this video was done a while ago, but thought I'd ask anyway. I have one of these units. It seems pretty useless. No amount of fiddling with the controls seems to make much of a difference. Phase control does nothing; the main antenna gain increases/decreases volume only, aux-antenna gain does nothing. Perhaps it's because my noise antenna is an OCFD dipole and my main antenna is a fan dipole?? Too similar? Most of the noise sources around here are due to the usual urban stuff - power lines, streetlights, etc. Base noise level on 40 meters is about S7-9! Thanks - Bob KJ6GEU
I experimented with both vertical and horizontal noise antennas and concluded that the noise antenna needs to be vertical. Horizontal antennas don't receive as much noise because RFI is vertically polarized. The unit will work as described with the correct noise antenna attached.
@@KA6WKE - same results with a receive loop antenna which has been well-reviewed for this purpose. Maybe the suburban RFI levels in addition to my solar panels are too much for this to work at all. Bob KJ6GEU
One comment. Keep your ferrite away from any metal plane. Having a plane alongside the ferrite significantly reduces its effectiveness. an inch or two is usually sufficeient. Also, genearlly use AM to see and hear RFI. I noticed that your first measuremnt "before"was in USB mode on a slightly different frequency, and your "after" test was done using CW mode. For consistency you should use AM for both and use the exact same frequency. I know these techinques with ferrite work; consistency just lends to plausibility of the efecetiveness.
Thank you so much for the video, it is a unique instruction how to replace the battery on this model of the Doorbell Ring. I suspected a dead battery on mine but it turned out it was just a bad connection of the battery. Just disconnecting and reconnecting the battery fixed the problem. However, my problem was to access the inside of the device since I hesitated to use force to remove the metal cover. After I saw you doing it I was encouraged since I was sure that it will expose the other two hidden screws. Anyway, thanks again and 73 from a fellow ham W5DMA
From a fellow Ham Mark thank you! The toughest part when fixing electronics for me is figuring how to get the device taken apart without breaking it! Your video is timely as I just discovered that our battery no longer holds a charge and requires replacing. Thanks again Hugo KA6KQL.
Thank you for taking the time to make this video and share. I am having alot of RFI (S7-S9) and I am going to start with the common mode solutions and work my way to the transmitted RFI. I may have some nosiy power lines out back also that I am discussing with the power utility. Nicely Done!
Thanks to you my friend, it took me seven minutes to change out my Ring battery. BTW - You can still find this battery. I found mine on Amazon (B15169) in Jan 2023.
