You had me confused Ron, I thought you might have redesigned the buffer while I wasn't looking! 
John,
I'll send an email. I would like to purchase a kit of one of these. Thanks again for all you do for us in the hobby.

GRJ, thanks for the heads-up on limited availability on this. I'll take a fully assembled unit, if any left. Thanks!
Ron
Send me an email and we'll fix you up.
John, I totally respect you for your dedication to this group, "WOW!". How many of us would take on a project like this to help others? You and the late Dale M. fantastic people.
Thank you and God bless you
Ray
If you can - send me one - thanks

John send me info for the booster and I also have at least one engine I need your help repairing. Thank you!
Folks, I have two kits left, and that's all. If someone is really wanting as assembled unit, I can build one or both of the kits, again that would cause a delay as I do them as I get time.
If there's really a lot of interest in more, I can order more parts, but it'll take some time as I need more PCB's, boxes, and power supplies, those take a few weeks. Obviously, the Digikey parts come in a couple of days.
Hi john
can you build one of the kits for me
thanks Rich R in
Please send me an email.
John
i just sent you an email for the kit build
thanks Rich R
Can you build another one for me please?
I have more parts on order, but since stuff like the power supplies and plastic enclosures come from overseas, it'll probably be 2-3 weeks. I also have to prep the cases with the holes and slots. I'll post here when more are available.
Hi John - I'm not in a rush and would take an assembled unit whenever ready. I think I e-mailed you earlier this week.
Thanks.
Got you in the queue Richie. 
Gunrunner John, Question, does this kit help the Cab 1, Cab 1L, Legacy Remote, have better control of the engines at far corners of a layout? Specially if the trains in a part of the layout 15 feet away from the TMCC/Legacy bases? Sometimes my Cab 2 loses control of the engines. Just wondering if this is the fix. Thank You very much for all you do for our hobby.
No, this has nothing to do with the link between the remote and the command base, it's affecting the track signal out of the base to the layout. The RF link between the remote and command base is a whole different conversation.

Larry, I had a dead spot on my track that I could not overcome. It developed over a period of time. I tried everything.....I purchased this booster for John, and it was the best $$$$ I have ever spent on my layout. Well worth the investment.

That's the problem that the buffer addresses. The link between the remote to the command base sounds like what Larry is asking about, the buffer won't help with that issue. For a CAB2, I've used a hi-gain antenna on the command base, and on one instance, I actually used a 2.4ghz WiFi amplifier on the command base. That really increased the range, and for really large layouts, it would probably be a significant help.
John please confirm you got my request for an assembled unit. This was the first time I used the private communication thing. Thanks George
Look at your profile, I even answered you there. 
Larry, the very first thing to try is changing channels! I'd try 1, 5, and 9 first, then try the intermediate channels. It could be something interfering, like your home WiFi router. If that doesn't do it, then you start talking about amplifiers.
Gunrunner John, I’ll do that, thank you very much. I deleted the other pictures as it was just to show you the front and back. Happy Railroading
Hello, I have not started my layout yet, but have the design done. Just finishing the room where it all will go. The layout is 32' long and 13' wide. I'm very new to all of this so I will admit I'm ignorant to all the electrical things as of now. So, how does this all work? Will it help me in the long runs I have? Cost? I can send a picture of my layout if you need to evaluate my need. I have a large collection of MTH and Legacy Lionel. Thank you Bob Huntnfish737@hotmail.com
Bob, I doubt you'll need the booster unless it's an unusual configuration, usually it's large and multi-layer layouts that end up with TMCC/Legacy signal issues.
BTW, what do you fly?

Also, I'm looking for a #4023 Bigboy....if you know of one available, let me know. Thx Bob

I saw the stripes, but I didn't recognize the cockpit.
I haven't seen many BigBoy's floating around, I did have a couple extra a while back, but I sold them when they went up in price.

Gold stripes...Delta, or former Continental? AA is parking all of our 757s, so I’ll never get the chance. Bummer...
I’m stuck with the bus calling us a retard every time we land.

I'm former North Central (1978), then through mergers: Republic Airlines, then Northwest, then Delta. Four different uniforms in the closet. I retired off the 747-400 three years ago. I flew the 747 for almost 10 years and it was a real kick, but my most favorite in my 39 year career was the 757. Northwest only had the 757's, but after the merger with Delta got to fly the 767 also. Same type rating, and we would see a mix of both on our rotations. I think most of the 757's and 767-300's are now parked. Only the 767-400's are being used. If I could go back and fly one more trip, it would be on a 757. Unfortunately, only in my dreams....

Did you ever operate out of Minneapolis? If you did, you very likely knew my aunt. She has been with Northwest/Delta since 1975, and will be retiring next spring.
I was never based in MSP. Flew through there hundreds of times, overnighted numerous times. I was based in Chicago until the crew base closed in 1984, then flew out of Detroit. Never lived in Detroit, commuted there from Florida. I’m sure I probably would recognize her. Was she a gate agent or flight attendant?
She did a bunch of stuff... gate agent, ground traffic, flight simulators over in Eagan. Susan Tennis is her name.
John, quick question, finally hooked my booster and if fixed my issue of having a bad signal on a piece of track that i was using as an insulated rail. One question, i have one of the newer ones that have a pot on it. The printed instructions did not talk about it and i did not was to go through 19 pages here. I am guessing it is for the signal, but how does it work?
Tony, that's a good question. I never got around to documenting that as it was a late addition. It does indeed vary the amplitude of the TMCC signal. This allows you to "tune" the signal to minimize any interaction with DCS and also to reduce the amplitude if you have issues with stuff like LCS Sensor Tracks.
Even with the signal turned down to minimum, the buffer is still providing a substantial benefit, it gives the TMCC signal much lower drive impedance so that it can drive more track capacitance. There are people that run it at the minimum with good results, it fixes their signal issue at that level.
The way to use it is simply turn it down as much as possible while still solving any TMCC signal issues, that will insure the maximum compatibility with device that may react poorly to too much TMCC signal.
Just to make sure, which way is less, left or right?
CCW is lower, CW is higher, just like your radio volume control.
I had to turn mine down a bit because of the interference to a sensor track. I just adjusted it until the sensor worked again.
