The link to MBL4 is dead and the software has been replaced with not so userfriendly Sonos.
Breakaway would be a good alternative if the developers didn't force you to use their god awful presets, which drastically cut down on mid range sounds and jack up the highs to levels that cause distortion.
I guess it appears that there's no viable software solution. I use a BSR equalizer and run flat, with the exception of cutting out highs above 15 khz. This seems to work the best.
I was able to fix the over modulation by changing the L/R Ref Level to -14.9 db, but the problem is this software forces you to use a core preset, which in turn cuts out the 250 Hz to 1 KHz range. The end result, the sound coming through on your radio is total, weak garbage. I don't know why there isn't an option to run FLAT! This software seems like a complete joke to me, unless I'm missing something?
I'm using this software, but it's causing extreme overmodulation when I run the sound through the transmitter. Before when I was ust using my sound card, it was fine. The sound appears to be capped at 0 db so I'm not sure what the problem is.
Can anyone give me some tips on what settings to adjust?
I'm not sure. I can't seem to find the part number in any documentation on HLLY's website. Oh well....I guess I won't worry about it until I need to :-)
Is it just a case of unsoldering it from the board and putting a new one in? Do you know where I can buy one? And will the current, suspected damage to my transmitter cause issues in signal strength or sound quality? It still seems to be working fine and I've always lived by "if it aint broke, don't fix it."
Damn you were right cmradio. After making a dummy load with the resistor you recommended the transmitter doesn't warm up at all. I'm surprised it lasted this long given I was using that other resistor for over a year!
Regarding the range, the terrain around here is hilly and there's lots of crap in the way to block the signal. There may be issues with HLLY regarding spurious emmisions but I don't think range is an issue (or sound quality for that matter).
Come to think of it, the resistor may be ceramic and I don't know if it's non-inductive. It's a zicon "cement powered" resistor. Will this eventually lead to transmitter damage or am I in the clear since I've been using it for so long without problems?
The 3 mile radius was not an entirely clear signal. It would start to break up between 1.5 and 2 miles. And then it would fade in and out until 3. I basically drove all around the city and then mapped where I was on google maps. That then told me the distance. The antenn was also in a terrible spot when I did this test. On the main floor of my brick ranch house. If I were to have a proper antenna mounted 30 feet up on a mast, I'm sure the range would be down-right scary.
The resistor is white, but non-ceramic. It's actually rectangular and has a rough, hard suade-like texture. I have no idea whether it's non-inductive. All I know is it's rated at 50 ohms and 10 watts; and has had heavy use (hours and hours and hours) without burning up the transmitter. The transmitter does get warm at times but never hot to the touch.
I would think the FCC would be more lenient considering forethought was put in on my part to minimize the range. Then again....who knows right?
I have a 5w HLLY transmitter that is running on reduced power. It normally takes a 12 volt power supply but I have it running on 7 volts. Also, it's transmitting into a 10watt resister dummy load (not an antenna).
Before, when I was running on 12 volts and using the antenna, it would go about a 3 mile radius!
Now, it only goes 1000 ft or so (4 or 5 houses down) and doesn't even reach the end of my street.
I was wondering what the likliness of me getting caught or busted is. I'm in the US.
