Close HP tower 6-7 miles away 100,000 watt cause a inrush of static on my conventional frequencies?

[crippledchicken]

I seem to notice this problem when there's HP transmissions going on latter in the day and evening not so much, late at night and early morning when HP action is of very little. SDS200 Thanks I've tried all filters. The HP is on the (MOSWIN)

100k watt?

 

[crippledchicken]

100k watt?

I think, but I may be misinterpreting the Database! May be 100 watt LOL!

 

[mancow]

Yea it's 100. What filter? Is it a vhf or 800 site?

 

[crippledchicken]

it's vhf

Maximum legal power for medium-wave AM broadcast is 50kw (50,000 watts) OP probably means 100 watts. Is it static or digital data noise?

 

[crippledchicken]

It's the closest tower to me also, I know of.

It's loud crackling static that sometimes goes away, during the conv. transmission that's what makes me think it's the HP and when their transmission stops, so does my interference Just a guess on my part.

 

[mancow]

Well what freqs are you getting interference on and what are are the moswin site freqs? Compare them for potential conflicts and work from there.

Experiment with the filters to find which one works best.

 

[crippledchicken]

155.55 154.875 152.405, are the frequencies that are affected The HP frequencies are listed as 155.43, 172.4625, 170.4625, 155.325, 154.98, 169.8875

When I find a filter that helps, then the HP/P25 starts to get more unintelligible but, I may have to just make a compromise

 

[crippledchicken]

Wow, I don't know where my bold type came from in my last post!

You must have clicked on the B above the reply window.

 

[crippledchicken]

I think I'll put my sds200 on hold on one of the problem frequencies then, hook up another scanner and just see when HP transmits on scanner #2 if it effects my conv. frequency on the sds200 might be worth a try.

Is this system a simulcast system? It might be due to simulcast distortion.

 

[tvengr]

I believe he is having problems with vhf and uhf conventional frequencies.

 

[buddrousa]

INTERMOD is the problem he is having
Options
#1 Filter every frequency on that system 3 to 5 filters not cheap.
#2 LAST RESORT Move.

Well, since I was getting full 5 bars before, I installed new coax I think the problem must be the excess coax all coiled up on my porch plus, I just spliced into the very old probably 15ft. section hanging down from the Radio Shack Discone antenna which, by now could have connection problems also. I've got to wait til I can get one of my grandsons to drop by when they are not working and help me get the antenna down and run the new coax without the splice since I made sure I got enough because the way I had it was just meant to be temporary. My WS 1065 Whisler won't pick up the conv. without lots of noise and won't pick up my local weather anymore either. It's pretty amazing, how all the MOSWIN stuff is coming in just fine so, that leads me to believe that it is more the position, coils, etc. of the coax than actual connection problems. I appreciate all the help folks!
