1st experiences fiddling around with my 1.8kHz filter

I have no audio clips yet, but i have been playing around with the different settings.
Some things did not  work the way i assumed they would be.

  1. A filter screws up your audio quality...
    No, the DSP in the 480 has enough power to keep the signal sounding normal.
    The people do not sound nasal at all.
    just add/remove some high/low and the signal sounds like your used to.
  2. You wont hear the nearby signals anymore....
    No, you will still hear then , just a lot, i mean A LOT less.....
    Especially with a strong signal, when you punch in the ATT you will really hear the difference.
These are for me 2 huge huge HUGE advantages.....

Also the overall feeling of the receiver becomes more calm, not really sure how to explain...
I'll try to make it more clear when i have the time to make some audio clips.
Especially when listening to the 40m band it's an awesome thing to have in your set. Stations become more distinct and clear.

Yes its expensive, but after 3 days i already forgot the price ;)

A new toy for the TS-480...... a 1.8kHz filter..YF-107SN

Today i drove a long way down south to collect something i wanna use during the upcoming PACC contest.
I can tell you , its worth its weight in gold.it's small and its tiny :)



Yes, i finally got my 1.8kHz filter. The YF-107SN. It was a 80 minute drive getting to the store, and the same 80 minute drive back to where i live.

So how tint is this thing actually then.....Let's open the box...






Big box, small content....



Ok , i dont think the ppl who never have seen a filter, know exactly how small current filters are...
So i took a picture with a standard sized lighter and a standard 1/4 watt , 5% resistor.....'





Seriously, the lighter is not a big one , its a standard size :)

I forgot to take a few pics when I installed the filter sorry :(
So I will take them next time i put in an other option.

I listned to the audio with the small filter , and it does what i wanted it to do so that's a good thing.
Nearby stations (frequency wise, not distance) do get a lot softer to the point that they do not disrupt the station anymore which i am listening to. so hurray for that :)

I will see if I can get a few audio samples and upload them somehow, so you all can hear the difference.
