All, GM might argue the point. From their website: <https://my.gmc.com/how-to-support/entertainment-connections/displays-radio/infotainment-system> My son has worked for the infotainment group for the

Greetings Hidehiko San, The MagicBox can handle 10 watts safely, but not a lot more. I've never tested it above 10 watts, so don't know at what power level the smoke starts to come out of it! :-) Have

Ken, Files for the MagicBox and SS-40 cases attached. 72, Jim, K8IQY PS...I need to get back with the 4 State QRP gang and maybe have them host these files on their web site.

Thanks for the kind words Ken. I'm getting too long in the tooth to do many more designs. By the way, I have designed 3D printed cases for the MagicBox and SS-40 Rx/Tx combo if you have a way of print

Hi Ken, That's the latest version of the PCB. I was hoping that you might have a cell phone with camera to take a photo or two of the PCB as it currently exists. Yes, that is correct, no keying, just

Sorry, 2N3904 transistors at Q14 and Q15; hands don't seem to be working at 5 AM this morning.

Hello Ken, That kit is getting long in the tooth! :-) Can you send along a photo of the PCB as it currently is built, top and bottom sides so I can have a look at what you've done so far? Can you veri

Bob, Here: <http://k8iqy.com/qrprigs/2n26/2n26page.htm> Performance could be improved with a better transistor than the PN2222A, but that was part of the experiment, to see how well that part worked a

Jim, You can design crystal ladder filters within the AADE Filter program. I'm not aware that Neil ever had any other programs available for doing crystal filters. 72, Jim, K8IQY

Got them Terry, but don't see the Cricket on the main kit page. The Cricket page however is working if you go directly to it. Nice job again for 4SQRP! 72, Jim, K8IQY

Sounds like a home brew NorCal SST design to me or maybe something earlier than that by K1BQT. 72, Jim, K8IQY

David, If you have both the SS-40Rx and SS-40Tx board, a MagicBox is not needed to connect them together.� All of the Antenna and T/R switching is taken care of by the combo. 72, Jim, K8IQY The SS-4

Indeed not, but on Gerber Plotters, which was the original plotting system used for making PCBs back when. 72, Jim, K8IQY

Terry, I would be happy to help, but only if your project can work around my summer schedule.� We will be going here and there a couple of weeks each month for bluegrass events, otherwise, we are ho

But the TP-41 was recommended for the Rx board only, not the stack. The assembly needs at least 2 1/2 inches of height to fit in and 2 3/4 is probably better so there is some additional volume above t

I don't think is will be tall enough to get the Rx/Tx stack in.� Just guessing though.... 72, Jim, K8IQY

Good!� Thanks Dave. 72, Jim, K8IQY

Yes, that is it.� Too bad the TP-41 case is no longer available.� Hopefully, John can use those dimensions with another case.� John, before drilling a real case, make a front and rear panel of s

Yes, I believe that is it.� Thanks Dave. 72, Jim, K8IQY

Please enjoy those John.� :-) It was probably removed when the Ten-Tec case became unavailable.� The case only worked with the Rx anyway, not with the stack. Neither did I.� It is gone..... I ca
