Re: BE AM 1A Power meter not working in FWD

Ironically I just this week worked on an AM1a that after replacing a couple of RF module fuses, appeared to be operating normally but the power meter only reads about 200w. If the old base current meter is to be believed, it is within a few mils of licensed base current.

Re: Strange skills learned

And if you have satellite dishes, you learn to build forms and pour concrete. http://cnypraxis.org/wordpress1/wp-content/uploads/2018/06/ConcretePad.jpg Jeff That's why I almost exclusively use non-penetrating mounts these days... Cost is within a few hundred bucks of a pole, making 2 trips to the ...

I don't know why it took me this long to think about it, but how about loading Win7 or something older in a virtual machine using VirtualBox? I do that when I need software that doesn't run natively under Win10.
That may be the answer if it doesn't run on the new laptop.

Re: AM Tuning Unit Design Software

Win7Pro. I have Grant Binghams network design and it refuses to run on "some" installations of Win7 (32 or 64) and any install that I have tried it on Win10. Interesting. My copy runs in Windows 10 x64 without much whining about it. I had a friend with more M$ certs than he can name look at it and ...

Re: AM Tuning Unit Design Software

What version of Windows are you moving from? If they ran in 7 they should run in 10. There are some real old programs that are actually 32 bit but have 16 bit installers which prevent them from being installed on any x64 flavor of Windows. There is a workaround, though. If you've got old DOS stuff,...

Re: Transmitter plant ambient temps?

I remember being told about a semiconductor rule of thumb: every 10C extra temperature halves operational life. These days I see more problems with overheated capacitors and connectors than the actual semiconductors. I have always used the rule of thumb that a decently cool (80's) degree tx room is...

AM Tuning Unit Design Software

Hi all, I have a number of free & cheap pieces of software that includes Tee-net design. However, it appears that a couple of my favorites don't run (or don't run correctly) in Win10 and I am about to have to move to Win10 on a new Toughbook AND have 3 or 4 small tuning projects coming up quickly. W...

Re: Tomato Soup Incident

I have ran various contaminated circuit boards thru a cycle in our dish washer. Most of the time it works, sometimes not. "sometimes not" meaning I get caught. :lol: As they say in the political world... The coverup is worse than the crime. Especially when Connie finds the dishwasher strainer stopp...

Re: Compression Question

I even more strongly 3rd the suggestions above.... No heavy compression, very limited limiting, good normalization. AND if your show is satellite syndicated, check with your sat provider on what their "normal" level should be. I have a couple of sat switchers set up with duplicated input channels wi...

Jim, Since tomato juice is supposed to wash away skunk scent, maybe it works in reverse... You just have to catch and milk the skunk. All useless, funny visions aside...

Re: Am I a possible engineer candidate?

Curt, As others have advised, keep your day job and slowly build a clientele and test equipment... Only after securing enough of a client base to replace your current income/perks/benefits consider moving to self-unemployment... You can often make pretty good money at engineering as a side business ...

I had forgotten about the old SA and whatever the other SEDAT RX was. I have a station with at least one of those down converters still hanging on the wall.

Re: C-band TI

And hope the LNB is using a standard L.O. of 5150 and not one of those odd-balls. While 5150 is normal, I have seen some unusual ones on older dishes. Wow... That would cause a bit of consternation. I have never ran across a C-band LNB that used an odd LO but have worked around KU-band dishes that ...

Re: C-band TI

As I recall, the military radar is just above the top end of C-band, we saw some of it from a nearby ANG base, but then they switched to radar up near the KU band. And just a reminder in looking for sat interference with a specan... The L-band output of the LNB is inverted in relation to the C-band...
