After seeing Stereo Microscopes mentioned here a few times I’m looking at investing in one. I see there are two types. A binocular style or a digital camera type with monitor. I’m leaning towards

Ken, the pulse noise problem is interesting, and I wonder why you hear it and I don't. Could it be the orientation of the GPS module? I have mine flat on the bottom of the enclosure, away from the

Yeah, I forgot about that too because once it's set you can forget it. Good job tracing back to it -- 73, Dan - W2DLC

Problem solved. It was the PCM1804. After replacement all is ok. 73 Ludwig

Okay, geniuses! We are back to operator/builder error! It works perfectly well and my attention should have been drawn to: 1. RTFM 2. Page 8 of "Shack Clock" v1.03 QCU Operations GPS {Mode Baud} 0?

Chuck is correct that trying to hit 160 through 6 meters with a single output transformer at T501 has to be a compromise. Another compromise may be in having each LPF hit multiple bands. There's 6

I may figure out how to do this...will have to look up reverse beacon to start and then how to evade morning chores! -- 73 Karl KI4ZUQ

Are they still at the same location in Van Nuys?

yes it is a easy thing, gives a save feeling :-) Hope to meet you on the air. 73 hanz

Indeed Franco, I am now designing the PCB. 1 ATTINY404 2 2n3904 3 optocouplers and a few resistors. should be do-able. 73 ciao hanz

Hi Hanz, why not to put everything inside the QMX+ ? I think I'll fix it inside the QMX, there is a lot of space there ! Ciao. Franco

Very well Hanz, I'll do the same using Arduino Nano that I have already here. Tnx to all. Franco ik2njv

I would be happy to help anyone wind their toroids. I live in Milwaukee, WI area. If you are close, we could meet and I'll wind them for you. If you want, you could send them to me and I'll send them

Me not yet. But I have today ordered some 33uf smd caps. I intend to glue one to the top of the board as close as possible, then run a couple of fine wires to pick up the connections. Plan to do this

Thanks for posting that Stan. Very helpful. Has anyone implemented this work around on a revision 1 board, where C430 lies underneath one of the SMPS boards and there’s nowhere obvious to site the

Got it fixed Franco. I intercept my key and delay setting it trough to the qmx in mean time i switch the amplyfier. Now i have swr protection on, no problem. 73 hanz YL3JD

Hello Don, Got it working with intercept of my key. I use 25mSec delay this is the time the relay (i assume)needs to switch. Still need to measure exact switch fly time. Draw back is that the side

Hi Dan, my chimes sound quite good, but I did get an annoying continuous tone so I came up with the muting idea. I really wish Hans could link the number if chimes to the hour. At the moment it just
