That's normal. It makes taking FI readings fun.
I would have expected the FI to drop during pauses if using MDCL but have never looked at one with an FIM...

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...

Re: Tomato Soup Incident

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... A good bath in a mild soapy water with a really good rinse in clear water and a couple of days in the sun to dry will tell the tal...

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 ...

Re: C-band TI

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...

Re: C-band TI

It certainly may help but if the interference generator is zipping around the sky around your site, it might be behind/beside the dish one minute and bore sighted the next. Seeing what exactly is causing the interference is going to be important. Down here in TN we don't have too much AWACS interfer...

Re: C-band TI

John, If it is military radar, an "AWACS" Filter might fix your problem much easier. In general, the radar signals are outside the sat downlink frequencies BUT are so strong that they overload either the LNB or RX front end. These filters are placed between the scalar and the LNB and filter signals ...

Re: RX-only C-band receive station registration, form 312

OLD, OLD, OLD Harris Corp (not necessarily Harris Broadcast but basically the same). Possibly not even 2 degree compliant. I may have a spec sheet on it somewhere and still have at least 1 in standby operation.

Is the LNB mounted on the back of the dish instead of out in front as normal?

Re: DX50 air flow switch

It had a pizo buzzer that would squeal it's little heart out if the flushing fan quit and IIRC was only mentioned in an addendum or service bulletin. Yes it would - and shut off the transmitter. I had to re-cap several of those to stop squirrelly operation. Also a chronic dust bunny will act as ins...

Re: DX50 air flow switch

The air switch is S7 on the A19 board if I remember right. Its in the very right cabinet/driver section. Any one have issues with the switch going out? Its some kind of whiz bang solid state device???? No paddle or real air preasure setting, that I could see. And its soldered on the A19 board. Any ...

Re: Omnia FM HOT OS

I have no experience on home brewing something like this but recall seeing in other "card-as-HD" equipment that to boot from a card, the card has to be formatted or somehow setup as bootable and IIRC something else done to change or maybe create a boot sector. Sorry but I don't recall exactly what w...

Re: GATES ONE IRF-350 REPLACEMENT

I'm going way out on a limb here, but given their age now, if you have a cranky SX-series rig, you might give the cans a shake. If the caps are over about 8yrs and the TX is not living in a refrigerated hut... Just go ahead and order the cap kit. I have one Gates1 that I am about to change the caps...
