Re: Just for fun!!!
I hope you're not kidding.
For MW I'd be pretty happy to see them use the CXA1129N. Though it needs to have far better tuning control than the SRF-59. About ten times better. For FM, they have to use

Just for fun!!!
The AM DXer's in the US, have the venerable "Super Radio" series and the japanese ICF-EX5. Both getting long in the tooth, and both having room for improvment.
With that said the powers that be at

Re: SRF-M37V and SRF-M37W-Performance differences?
Almost sounds like grounds for using a off board DSP filter, and a loop antenna for more directivity. Ofcourse that throughs it in to the ultralight unlimited class. Bummer!!! :>(

Re: SRF-M37V and SRF-M37W-Performance differences?
So in the end it's a useless exercise?? Too bad it would be nice to find some improvment for it.

Hi Alex,
Actually even replacing the horrendous IF filter in the SRF-M37V with oneof the modest 450 kHz upgrades would place the radio in the "unlimited"class. Because of this, fanatical tinkerers

Hi Alex,
Whether the 450 kHz filter modification would be useless or not probablydepends on the type of DX you pursue.
For domestic DXers looking for a little more sensitivity, the modificationmay

Re: SRF-M37V and SRF-M37W-Performance differences?
Thanks, Gil! Can you copy me as well? I am thinking about getting the
narrower version of the filter, and would like to provide it to my friend
who has agreed to do the work.
Thanks!

Sorry, it was done by someone else, so I'm afraid I don't even know what
