![]() ![]() i am not saying that SDR gear is crap, not in the slightest, but I am saying that any SDR gear NEEDS hardware to make it truly competitive against even the older gear when it comes to actually hearing a weak signal parked between two strong ones. ![]() We have simply seen the introduction of so much shitty dual conversion gear in the past couple decades that rely on software to do the job that hardware should be doing that we have lost sight of the fact that the proper way to do something WAS the way it was being done all along. Modifications for the ICOM created 28-03-2002 from (AH-4) Icom, AH-4, AH-3 ( automatic antenna tuner ) connection to any radio. Basically what I am saying is that triple conversion receivers are NOT just coming into the market but rather have been around for decades. The Yaesu FT-767GX was triple conversion with IF's at 45.030 MHz, 8.215 z, and 455 KHz. the now nearly vintage Kenwood TS-430 was triple conversion in FM mode and dual conversion in AM/SSB/CW modes with IF's at 48.055 MHz, 8.830 MHz, and 455 KHz in FM mode only. The IMD difference between these receivers is quite obvious. However, if you want a receiver with good SSB performance and much better filters and IMD performance than the FRG-100, the R-70 is for you. the ICOM IC-740 was triple conversion with IF's at 39.7315 MHz, 9.0115 MHz, and 455 KHz. If you want good sounding AM, then the R-70 is not a good choice unless you make the AM detector modifications. The Icom IC-745 also was triple conversion with IF's at 70 MHz, 9 MHz and 455 KHz.
