#Ic 7800 receiver price generator
Parameters: Measured with a signal generator while running AM mode with 6 kHz bandwidth, AGC off, and using 30 % modulation of a 400 Hz tone. I had hoped to see it a few dB better, but it equals the SDR-IQ, a bit better than the QS1R and marginally weaker than the Perseus and the Winradio Excalibur (G31DDC). A uniform -101 dBm or 2 uV was measured from 600 to 20,000 kHz. I finally got round to measure my new netSDR from RF Space too. On SW, it was marginally less sensitive than the IC-7800. The R-9000 however is an older model, and it was indeed rather deaf on MW with figures around -92 dBm or 4 uV. This was confirmed for the IC-7800 as I measured a uniform -106 dBm to -108 dBm (around 1 uV) throughout most of its frequency range (600 to 20,000 kHz). As far as I know, all their radios produced in recent years are not desenstized on MW. The IC-7800 is stated (as all Icom receivers and transceivers are) to have reduced sensitivity below 1.8 MHz. Of course I never resist the temptation to measure the sensitivity of a receiver. Lots of thanks go to Olav Skår, LA9VFA, who let me play with these superb radios. Both very high end, both in terms of performance and price. Two of the latter category are the Icom IC-7800 transceiver, and the Icom R-9000 receiver. Some are/were mine, some were here on a temporary basis. As an aside, anyone know of anyone that does a good job fixing Icoms? I don't dare fool around in the innards of these high-fluting, modern rigs with their tiny components.I've been fortunate enough to have a large variety of receivers coming (and going) at my Kongsfjord QTH. I will likely send the rig back to Icom America, which is a long ways from Florida. Having to get used to the usual "split" feature of most rigs without being able to listen to both frequencies at once is a pain (yup I know, got spoiled, huh?). While you can watch both receivers on the scope of the IC-7800. I *really* like the 2nd receiver, and use that quite a bit. Representative example: Cash Price: 1199.95, Deposit: 120.00 Loan amount: 1079.95. Add over 45 years of analogue RF circuit expertise and the result is the IC-7600, a new rig with outstanding performance and a multitude of innovative features including a newly employed double conversion. Ģ) looking at another make/model high end rig. The IC-7600 HF/50MHz transceiver is enhanced with some of the main features tried and tested on our flagship IC-7700/7800 models, highly regarded by Amateur operators world-wide. after getting it fixed, I'm thinking of selling it and either -ġ) get a new 7800 with all the modern fixes. RF in the headphone jack, receive preamp 1 blew out after a nearby lightning strike years ago, no 3rd roofing filter. Lord knows I've run the rig hard and have gotten WAY more out of it than I planned. It was a "first run" of the model, which I've had since 2005. So now, what to do? I obviously plan to fix the rig, but here's the deal. I quickly wondered if the output transistors had fried, turned up the RF output pot to maximum, keyed the rig again and the breaker blew. That said, however, the IC-756PROIII is not an IC-7800 lite. ICOM says it has back-engineered some of the ’7800’s design features into the PROIII. NO output, though the ALC meter registered just fine. IC-7800, which replaced the worthy and venerable IC-781 in the manufacturer’s lineup. Thinking I had pushed some button or set something wrong, I looked all around, pushed this and that, but nothing going. Just after working the ZL9 this weekend I left the shack for a bit, came back and noted absolutely no output from my 7800 when I keyed it.
