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. 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.....My R75 cost only $450.00 with free DSP included.It have installed 2.4khz,3.3khz,6khz filters, Pete's 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 hard core dxing. 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. |
