beverpix: I have the 2.3 Collins in both the 897D and the 817nd and the difference is MUCH bigger than in this video. Compared between stock ceramic and Collins it sounds like a totally different tranceiver (on both rigs!). The filter is worth its money 100% 73's!
kees konings: hoor weinig verschil .
0ndrous: For what application?
For Rag-chew, absolutely! Get the 2.9KHz from INRAD.
For DXing the Collins 2.3KHz is great but you might not feel it's enough improvement to justify the cost.
For contesting definitely get the 2.0KHz.
0ndrous: Having purchased an FT-857D with both filters (factory & 2.3) I do notice improvement in both selectivity and sound quality, & though not a major difference, it is an improvement and up to you if it's worth the $.
I'm springing for the 2.9 filter because I've heard a friend's 857D with a recent 2.9 upgrade and now it sounds as full & rich as an Icom Pro3, using the stock hand mic with a condenser element modification.
I'm more of a Rag-Chewer than a contester, though I do enjoy DXing, too.
A1200: Mmm I am not sure listening to that again, mine is more different in terms of audio tone, it's almost like the matrix is making connection to identify the filter but it is not making a connection. I would check it is inserted the correct way up and way round and pushed in properly. 73 Mike M0SAZ.
A1200: Yes but there is no adjacent QRM so how can you gauge the effectiveness of the filter? It is only slightly narrower than the stock ceramic filter but has better skirts, so the unwanted signals are rolled off more sharply. Of course a lot of this can be achieved using DSP too.
Antoine F4HJG: Try on LSB and listen the difference, Inrad have a filter 2.9 khz the difference is rely impressive
9m2pju: i will go for CW filter only.
crnazvijezda: Nice video! It looks like filter is not worth the money :( very sad but happy because I didn't spend money
ke4wsh: thinking of getting filters for my 857d should i
Toudiyama: get a 2 KHz filter from Inrad originally the FT 8x7 Bandwidth on SSB is already about 2.3 KHz, just look at a waterfall in a PSK program and you will see what I mean
And Why are these Filters so expensive compared to other filters for other radios?
even the inrad filters cost 140 $ a piece, these filters cost too much for what they offer and for what's inside of them
berny bord: its true for the price the difference its very little iven you cant hear it some time..
JORGE ALBERTO ROIG: is equal ---- not diference 73s jorge
Chef de NYC: Thanks! I'm more info ultrasound type of work. I learn most of the stuff myself online. Just only recently start looking for a school to make things "official". Hehe
