Just curious if anyone here has had the Kiwa mods for the Icom R75,
particularly the sync and filter upgrades. If so, what was the turnover time, and which modifications do you feel are the most significant for dxing? -Brian |

If all you do is listen to utilities, it is ok in its stock form. But, if you listen to shortwave broadcast stations and or medium wave, get the kiwa mods. The Kiwa 3.7/3.8 filter is great for dx'ing and the sync mod works very well. Add a good external speaker such as the Radio Shack Minimus 7 and you have an excellent receiver. The Icom dc power supply runs warm and provides way too much voltage too. Might want to use a "Real" 12 volt dc supply. Thanks Les. Do you remember how long Kiwa kept the radio to do the mods? -Brian |

I use mine with a Quantum QX Pro Loop and it is a fantastic mw/sw receiver. Les |

Les - Is the Pro Loop good above 2MHz?
I don't use the R75 at all because it is just sitting on top of my R8B. And to be honest the R75 is a little dissapointing out of the box. Too distorted I will try the Kiwa mods and put R75 in my bedroom maybe. Brian - please report back when you get mods done. I'm waiting for positive cash flow after Christmas b4 sending radio to Kiwa. regards, Bob |

Hi Les
I also own a Icom R75 but I added some extra filters to it. I added a pair of 2.8's {FL-96 and FL-103} so they would match up instead of the one more expensive 3.3 FL-257. I got the 2.8's for ECSS and for the cheaper price plus I read from people who bought both the 2.8 and 3.3 told me the 3.3 was just too wide and let too much carrier noise thru. Also, they said you couldn't really tell that big of a difference between the 2.8 and the 3.3 for the money. So, with what I have now, do you think I would really benefit from the added Kiwa 3.7/3.8 filter? I listen to everything actually. BCB programs, Hams, and SW broadcasts if I can get them in good. Do you think I should get the Kiwa filter added? I'm pretty content with what I have now but who knows what I might be missing out on? You are well experienced with the R75 and would appreciate your pro opinion on this matter. Thank you Glenn "Les" wrote in message oups.com...

The dual 2.8 filters are the way to go if you tune using ECSS, I absolutely abhore using ECSS for sw broadcast listening, and that is my reason for using the Kiwa filter module. Of course, if I am looking for a heterodyne out of Pitcairn Island, I'll use USB or LSB and the narrow filters. YMMV, I use a Sherwood SE-3 MKIII and a Kiwa Map as I hate pinched audio. Of course, if I am just listening to a in the clear SW Broadcast station, I use the venerable RCA CR-88A and a big 10" speaker, absolutely spectaclar audio! If you use ECSS most of the time, don't bother, as in its stock form, the R75 is fine for that. Where it suffers is the non-functioning sync detector and the agc on am compounds that. Les |
