The level of performance of the two receivers is about the same. The
R5000 has better audio, but the Kiwa audio fix for the R71 makes a lot of difference and isn't difficult to install. The R71 is much more user friendly in my opinion. The keyboard on the R5000 is horible.. Both are fine receivers Andy |

I've always been interested in SW radio as a listener and have decided to get more serious about it to see just how strong my interest really is. As a start, I want to get a good used radio, and it seems like the Kenwood R5000 or the ICOM R71A are very popular. AFAIK the Icom has rather high distortion in AM, which means it's more a ham/ute thing (when unmodified at least). Age related problems: The infamous lithium battery - doesn't seem to be flat too frequently (yet), but when it does it takes the firmware with it and you have to get the thing reprogrammed at Icom. The Kenwood apparently has good audio and is more a program listener thing, though the keyboard isn't all too appealing with its non-standard layout. Standard 6 kHz AM filter isn't too bad, but for DX the replacement YK88A-1 should be chosen. Age related problems: Tuning knob seizure. Good replacement crystal filters exist for both. (The respective 2nd IF is 8.83 MHz for the Kenwood, 9 MHz for the Icom. No, these 80s beasts don't use 455 kHz as last IF for AM/SSB yet, just as 3rd IF for for FM, which means good replacement filters virtually have to be crystal ones. The current IC-R75 uses a 2nd IF of 9.0115 MHz and a 3rd IF of 455 kHz, and allows using filters on both. The AR7030 also uses cascaded filters, all on 455 kHz in this case. Drake's R8/A/B uses a 2nd IF on 50 kHz to implement good coil filters - those in the R7 had a form factor of around 2, which is very good for this type of filters.)

I hate the R5000's tuning knob too, why no finger hole?? BDK BDK, There is a product "FingerDimple" that is available - - - to 'improve' the R-5000's Tuning Knob.

AFAIK the Icom has rather high distortion in AM, which means it's more a
ham/ute thing (when unmodified at least). I use my Kiwa audio upgraded R71a 95% on AM and have no trouble. A friend of mine has a completely stock radio and I could never find fault with it. Depends on how critical your ears are I guess. jw wb9uai |

Depends on how critical your ears are I guess. jw wb9uai Hi My receiver has the Kiwa audio mod and I have absolutely no complaints with it. I also replaced the stock wide filter with an LFH2SK 3.7 KHz filter from Kiwa. Even with a narrow bandwidth such as this, I can get very acceptable audio quality by turning the passband tuning knob to either the 10 or 2 o'clock position. It sounds at least as good as my Kiwa modified (filters and expanded audio upgrade) FRG-100 using the 6 Khz bandwidth. The R71 is a fine receiver and I personally wouldn't trade it in for anything else. Cheers Andy |
Have to agree with Andy there...I wouldn't trade my R71A for anything. I
bought the new R75 and it sits on top of that - I park one and drive the other. Absolutely fantastic radios in my opinion...both of them john kf4anc "Jerry" wrote in message ...

As a start, I want to get a good used radio, and it seems like the Kenwood R5000 or the ICOM R71A are very popular. It looks to me like the ICOM has more features, such as CW, RTTY, and a superior notch filter. This makes me believe it is aimed at the more serious user. Two web sites that review receivers rate the R71A slightly higher than the R5000. So, I would expect R71A's to be in higher demand, but it seem to be the opposite. R5000's seem to sell at higher prices and I see R71A owners wanting to trade for R5000's. What am I missing? Which would be a better radio for a beginner? I will probably start out with DX and broadcast, but may want to grow into other areas. Thanks for any advice. Jer |
Hi John
As you have both the R71 and R75, how do you find they compare? DSP aside, is there much difference in their performance? Have either of your radios had any mods or options installed? Cheers and enjoy your radios Andy |
