anyone have any reasons/recommendations to buy the optional 9MHz and
455kHz filters for swl? universal radio wants over $200 for the
narrower AM filters, half the price of the receiver itself....
or do you think i should just get a ten-tec...i really don't want to
spend more than $600.....

I've been using my R-75 with the stock filters for two years. I also
have experience with the Drake R8 series and the Kenwood R-5000 to
compare the stock R-75 performance to. IMO, you really dont need any
additional filters in the R-75. It does just fine with what it comes
with. In the situations where you would need a different filter, there
are tricks you can do with the radio to make up for it. You would get
some use out of an optional filter, but it wont be worth the money. The
beauty of the R-75 is that it is a very low priced receiver that has
performance specs well above its cost. It is a SUPREME radio in ssb,
for DX'ing and utility. It is an "adequate" radio for broadcast
listening. The best use of extra money on the R-75 is to buy a nice
external speaker. The next step would be the Kiwa sync and audio mod.
Other then that, it is what it is.... It will never be a top flight
radio for broadcast listening like the R8b. Spending money on optional
filters defeats the purpose of getting an R-75. That being, value for
dollar.
Just my 2 cents.

I bought the 2.8 9m filter for ECSS and Hams and I love it. Perfect for
those pesky AM stations and fantastic for Hams. I paid a whole $60
shipped off Ebay. My $50 rebate will pay for it.
The twin PBT on the R-75 can't be beat for DX'ing. The receiver is
extremely sensitive. There is no better rig for SSB for the money.
So for $485 {$425 for the receiver plus $60} I have a brand *new radio
with a warranty, a bunch of filters I can MIX and match plus *DSP. Throw
those twin PBT into the picture...and well you get the picture!

I paid $450.00 for mine brand new and it came with the free UT-106 DSP
untit. I did not buy any additional filters, but I did have the Kiwa mods
done. The sync mod was $45.00 and the audio upgrade was $35.00. Both
mods were worth the price. One interesting thing I noticed with the sync
mod. Asside from improving the over all performance of the stock sync, it
also improved the performance of the NR function of the DSP module.
Before the Kiwa mods, the best you could do was set the DSP NR to a
setting of about 6 before you got all sorts of wobble. After the Kiwa
sync mod, I can use NR settings all the way up to 15 without the
distortion I got before the mod. There was no mention that the Kiwa sync
mod would improve the function of the DSP NR, but it did. Using ECSS
with the DSP module and the twin BPT, I find I can clean up just about any
weak and messy signal. Given the possible combinations that those features
and be tweaked in, I never saw need for an extra filter. For only $ 60.00
though, I'd add filters. I'd want a 2.8 kHz filter in the 9 MHz IF and a
3.3 kHz filter in the 455 kHz IF. That would be kewl !!!! If you could
point me to where I could get them for $ 60.00, I'd buy them tonight !!!!

I bought it off this Chinese dude. He's on Ebay but I dealt with him off
Ebay.
Is that your e-mail addy? I'll send you his e-mail. Oh **** here it is. I
don't think he'll mind if it means bread for him.
He's in Taiwan but I got the filter in 8 days.
