Icom R-75 question
I know this radio has a great reputation for SW reception, My
question is how does it do on BCB MW reception?? Is an external speaker really needed? Neil Bell Neil Bell For e-mail replies remove the "notreally." |----------------------------------------------------------| |----------------------------------------------------------| |

BCB Hmmm..... - OK An external antenna helps; but this is NOT IMHO a bcb heavy receiver; It's designed NOT to really pick up BCB too well ( This eliminates overload) you'd have to have Mods done to make it a BCB heavy set.. - However, I can usually pick up BCB stations ~1000 miles away.. Is an external speaker really needed? IMHO, yes... Either headphones, or Computer-type speakers; ( I mean, No sense in Icom making a Huge cabinet with a Huge speaker if you can have a " here's the signal" internal speaker & a port for a good set of external speakers; ~ Dan ~ Neil Bell |

Is an external speaker really needed? The reviews I read before purchase did not sing any praises for the IC-R75s speaker so I had mine shipped directly to Kiwa for the following mods: --synchronous detector upgrade --audio upgrade --high fidelity audio filter --R75 filter module The sound is just fine, though for obvious reasons I can't compare it now to what is would have sounded like. __________________ IC-R75 / CW 40LP Yokosuka, Japan |
I've removed the MW attenuator from my R75, and now the unit has flat
response across the whole tuning range. It is not the easiest mod, but it is worth the effort. Pete D. Kim wrote in message m... Neil Bell wrote in message . .. Is an external speaker really needed?

Good joke, but in serious here what one of the top reviewer have to say about the R-75:Excellent ultimate selectivity and good dinamic range for faint signals,Dsp with aut notch filter helps improve intelligibility of some tough signals and reduce heterodyne.Two levels pre-amp allows excellent sensitivity to weak signals.After the removal of the MW attenuator [Pete's mod]my R-75 have .07 uv sensitivity figure in the MW band.In your complaining you don't mention the antenna you are using and this is one of the most neglected points in Mw dxing.With a first rate antenna you can overcome most of your MW receptions problems.You can try a Kiwa loop, Justice ant or quantum loop [internal] or a external loop like the K9AY.

The tiny speaker the R75 has can't sound very good. If you are going to
spend the money for those modifications then spend a little more and buy an external speaker. I'll agree with this point. I am a mostly-nighttime (bedroom) SWL and as such, I use headphones exclusively, regardless of which radio(s) I'm playing with on any given night. But, the few times I have used my R75 without phones, I immediately set up external speakers with some EQ to get it to sound full enough to seem 'real'... and this even after I had all modifications and enhancements done (mostly by me, including installing Kiwa's synch upgrade, which I simply bought from them and installed myself)... the R75's a fine radio with phones, or with decent outboard speakers. But the tiny, front-firing stock speaker isn't full enough to do the rest of the radio justice. Linus |
TELAMON,
So had Icom come out with an R75A and R75B model like the Drake R8A and R8B then it would be a good radio ?

The R8(x) transformer runs warmer than some receivers but in no way hot. I've never heard of any failure of the transformer or associated AC power supply components. The R75 doesn't have an internal power transformer. It uses a wall wart, so it's not a fair comparison. (R8B) ,bassy sound "virtually requieres a outboard speaker" [Passport], 'Passport' was making the point that the R8 requires an external speaker to fully appreciate it's audio quality but it's not mandatory. IMO- If any receiver needs an external speaker it's the R75. The OEM speaker sounds more like a cheap CB radio. The R75 sounds much better with an external speaker but it's still not as good as an R8, particularly for program listening. a cheap mechanical encoder used to have an above -average failure rate [Why not an optical one like in the AOR 7030+] The original R8 had an optical encoder. Drake says they changed it because it had problems. Tests by myself and some others on this group seem to indicate that the factory lubricant in the mechanical encoder is the problem. After cleaning mine and relubing it with a synthetic grease, it's been completely reliable for almost two years. I don't know if Drake has made any changes in the OEM encoder lube in recent models. The AOR-7030 also had problems with it's tuning encoder in the early models. ,a lot of birdies and background hiss [from the syntetiser board and some Poor shielding and grounding techniques ect ect ect..... The early R8B (1997) had more birdies than expected for a receiver in it's price class. The newer ones (since about 2000) have much fewer birdies. I had a 97' and now have an 01', so I've heard the difference. My R75 cost only $450.00 with free DSP included. It have installed 2.4khz,3.3khz,6khz filters, Those filters are not cheap. Take a look at Universal's website for the prices. http://www.universal-radio.com/catal...rxvr/0175.html sensitivity mod,339 comparator sync mod,Phidelity mod all this mods for less than $50.00 and not only "work as advertised" but work better than a R8B [and others expensive receivers] for dxing. There is no sync' mod for the R75 that makes it work as well as the sync' on an R8B. The Icom R75 does not have QC problems I'm aware of. It does have design problems and is the reason people have the units modified. All receivers have design problems. The design of any receiver is a compromise of cost vs. performance. I prefer to pay more for a receiver that doesn't need many (if any) mod's, than to pay less up front and then spend more time and money to get it working acceptably. BTW- I guess it was just a matter of time before this subject came around again. I think it's clear who got it going. This will be my only reply.

The Ten Tec RX340, Drake R8B and AOR 7030 perform to their specifications and function as expected based on the literature that describe them. ICOM made the decision not to fix the R75 design problems so people that want it to work right have to modify it. I consider the R75 as described to be false advertising. Cost has nothing to do with the issue of whether the radio performs as advertised. But what about companies like Ten-tec and drake .Ten tec owners are still waiting for the RX-350 sync det fixing and others flaws fixing[check the complains in the RX-350 yahoo group].What about the Ten Tec flaws that you can read in passport to world band? Why they don't fix then? An now we are talking about a $3,999 receiver.What about Drake R8b encoders,birdies,synthesizer circuit noise ect ect,?All companies including Icom make excuses and try to compensate with more advertizings in shortwave radio guides.But the difference with Icom is that they decrease the R-75 price form $1,100 to $450.00 or $525.00 and are including a free DSP but Drake and others are increasing the price of their receiver but they are not raising the quality standards,. I use all three radios with external bookshelf speakers or headphones because they sound better than the internal ones. The internal speakers are OK on all three radios. In the R-75 too.But I agree with you that ext speakers sound a lot better. The improvement an SE-3 would bring to the RX340 would not be worth the money to me. I donıt know where you got the information on static crashes sounding worse than on other receivers. I have had no sign spurious signals around 6 MHz either. I get the information from passport. All of the radios functions are not available or even make sense in all modes of operation. All functions are available and work as advertised. The noise blanker works against some noise types and not others just like any other radio Iıve used. I agree The Drake R8B does not run hot. Warm would be the best description. I have measured the case temperature to be just a few degrees above room, which is perfectly normal for a unit with an internal power supply. It is my understanding that ICOM has made several radios that you canıt keep your hand on however. A lot of R8B owners are using an external power supply now.The internal "international voltage transformer" and internal power supply circuit keep generating a lot of heat even if you turn off the receiver.[I don't read this anywhere I had a R8B sometime ago.] Iım not going to drop $450 - $500 bucks on a radio that I need to hack for the AGC and sync to work right and I disagree that even after doing so the radio ³is better² than the Ten-Tec, Drake or AOR receivers that is just your opinion not based on fact. That's your privilege.My oppinion is based in the fact that I tested both receivers for months and read almost all the reviews available but I'm not expecting that you like my facts. These days Iım surprised someone has not sued ICOM. If the price increase more than $700.00 in the next months I will be the first. |

I've never heard of any failure of the transformer or associated AC power supply components. The R75 doesn't have an internal power transformer. It uses a wall wart, so it's not a fair comparison. It run very hot and you know it Huh? What the hell do you consider 'very hot'? and in a past post to this group you attribute the problem to the "international voltages transformer" and you wrote that you fix the problem using an external power supply. (R8B) ,bassy sound "virtually requieres a outboard speaker" [Passport], 'Passport' was making the point that the R8 requires an external speaker to fully appreciate it's audio quality but it's not mandatory. IMO- If any receiver needs an external speaker it's the R75. The OEM speaker sounds more like a cheap CB radio. The R75 sounds much better with an external speaker but it's still not as good as an R8, particularly for program listening. The R75 external speaker it's not mandatory too.But a lot of owners are satisfied using only an external speaker with it.It's not a nice experience to try to do hardcore dxing with the R8B bassy sound and background hiss from the synthesizer circuit.I read your post asking Pete for help in this issue. a cheap mechanical encoder used to have an above -average failure rate [Why not an optical one like in the AOR 7030+] The original R8 had an optical encoder. Drake says they changed it because it had problems. Tests by myself and some others on this group seem to indicate that the factory lubricant in the mechanical encoder is the problem. After cleaning mine and relubing it with a synthetic grease, it's been completely reliable for almost two years. I don't know if Drake has made any changes in the OEM encoder lube in recent models. The AOR-7030 also had problems with it's tuning encoder in the early models. There is not excuse for a $1499 receiver having this cheap encoder.Ask drake for a pro one like the one in the R-75 and AOR 7030+. ,a lot of birdies and background hiss [from the syntetiser board and some Poor shielding and grounding techniques ect ect ect..... The early R8B (1997) had more birdies than expected for a receiver in it's price class. The newer ones (since about 2000) have much fewer birdies. I had a 97' and now have an 01', so I've heard the difference. 2 week ago I read your posting asking Pete help for the problems with synthesizer board circuit interaction cause by poor shielding and grounding techniques. My R75 cost only $450.00 with free DSP included. It have installed 2.4khz,3.3khz,6khz filters, Those filters are not cheap. Take a look at Universal's website for the prices. http://www.universal-radio.com/catal...rxvr/0175.html The 3.3khz filter cost $7.00 and the 6khz $30.00 [from a company closeout sale] nice filters with very good skirt shape factor. sensitivity mod,339 comparator sync mod,Phidelity mod all this mods for less than $50.00 and not only "work as advertised" but work better than a R8B [and others expensive receivers] for dxing. There is no sync' mod for the R75 that makes it work as well as the sync' on an R8B. All the R-75 with kiwa Sync det mod owners are very happy with its sync det performance.The difference is that we do the sideband selecting by hand not aut [using the 2.4khz filter and the twin PBT.]A shortwave receiver is not only a receiver with a good Sync det[the R8B sync det is not a perfect one]but a receiver with good stability,good skirt shape filters[the discontinued drake R7 have better filter skirts than the R8B [from passport R8B white papers],1hz tunning steps like the R-75,some DSP feature,good sensitivity,oustanding SSB mode [like the [R75],exceptional quiet circuitry [that the R8B don't have], and the most neglected part a good MW/SW antenna. The Icom R75 does not have QC problems I'm aware of. It does have design problems and is the reason people have the units modified. All receivers have design problems. The design of any receiver is a compromise of cost vs. performance. I prefer to pay more for a receiver that doesn't need many (if any) mod's, than to pay less up front and then spend more time and money to get it working acceptably. But the problem is that you paid more for your used R8B and now you have an expensive receiver that don't have DSP,only one pre-amp [R-75 two],not tune in 1hz increments,not tune up to 60MHZ,cheap mechanical encoder with high rate record of failure [you are the best witness because you had an encoder failure],a lot of background hiss and noise from the synthesizer circuit and "some birdies" a "Kmart" calculator keypad and tunning Knob and for some of this flaws NOT MOD AVAILABLE. BTW- I guess it was just a matter of time before this subject came around again. I think it's clear who got it going. This will be my only reply. I don't care who gets the last word. No me, I'm only reacting to someone who think that cost is synonymous of performance.Maybe someone who read and believe without question what Passport say about the R8B "It gets everything right" |

I'm glad you are happy with the R75 but I have read the manual and I don't like the way the controls operate and there is the problem that the AGC and sync circuits that either don't work or have performance problems that ICOM will not address so I would be relegated to voiding the warranty by modifying the radio. I would not be happy with an unmodified R75 as you are. The R75 has nothing new in the way of features or performance that I already have with the other radios I own. I would not call the way the squelch / RF gain knob operates as intuitive and from reading the manual it seems to me a novice could easily get the radio in a condition where nothing would be heard from it or have the sound grossly distorted. -- Telamon Ventura, California |

. For example a ten-tec RX-340? This one have some flaws too and cost $3,950.The sync selectable sideband lose look relatively easily,Passport recomend an external Sherwood SE-3 [500.00],poor dynamic range,static crashes sound harsher than on analog receivers.Spurious signal noted around 6MHZ segment,notch filter does not work in AM,Sync selectable sideband or ISB modes,Noise blanker not effective ect, ect, ect,.What about a Drake R8B? Cost $1,495, This one have a lot of flaws too,for example the power supply run very hot,[a remedy is to use an external power supply],bassy sound "virtually requieres a outboard speaker" [Passport],a cheap mechanical encoder used to have an above -average failure rate [Why not an optical one like in the AOR 7030+],a lot of birdies and background hiss [from the synthesizer board and some poor shielding and grounding techniques ect ect ect..... But what about companies like Ten-tec and drake .Ten tec owners are still waiting for the RX-350 sync det fixing and others flaws fixing[check the complains in the RX-350 yahoo group].What about the Ten Tec flaws that you can read in passport to world band? Why they don't fix then? An now we are talking about a $3,999 receiver.What about Drake R8b encoders,birdies,synthesizer circuit noise ect ect,?All companies including Icom make excuses and try to compensate with more advertizings in shortwave radio guides.But the difference with Icom is that they decrease the R-75 price form $1,100 to $450.00 or $525.00 and are including a free DSP but Drake and others are increasing the price of their receiver but they are not raising the quality standards,. It is reasonable to differ over wants and needs but specifications or facts are generally not arguable. If you misunderstand what someone has wrote and continue to argue some point (several actually) as you have been doing your credibility will be zero. "If you have a glass roof don't throw stones to others".I did the tests and I did the research looking for others experiences,expert reviews,an articles and after dozens of e-mails received from others honest drake and ten tec owners that want to fix their receivers flaws and not hide the facts [their receivers flaws] under the rug I react to others postings.If you check the R-75 yahoo group you will see honest owners sharing the pro and con of the R-75 and in the process finding the answers and solutions to their radio few problems.The myth of the perfect receiver without any flaw was found to be false.For example check the passport reviews and see for yourself all the ten tec 340 flaws that they found.If for you, passport credibility is zero thats ok with me,but if you like to go to a group like this posting about why you don't like the Icom receiver this is your privilege but don't begin to groan and talk about "zero credibility" if someone point out your own receiver faults. |
