#Icom ic r6 poor signal full
The point is that there would be a lot of gain as you go higher in frequency, and so there is a lot of RF Negative Feedback in the circuit to reduce the gain as you go higher, to flatten out the response.īut if you lose a Driver, you still have enough gain to get full output on 10m, but not enough drive as you go lower through the bands. You'd think you'd lose power on all bands, right? I was amazed that this could cause this strange effect. Radio Receiver ICOM IC-R6 (8.33kHz) The power of listening to the world in the palm of your hand is possible with the compact R6 Whether you are listening to a shortwave station, the local airport approach or ground communications, or simply scanning the various frequency ranges, the R6 offers the most frequency coverage for under 200.
#Icom ic r6 poor signal driver
It was simply one of the Driver Transistors had failed ! The DC conditions had looked fine, as it went E-B open circuit. Frankly it drove me nuts, as it didn't make sense to me (this was the first Transistor PA like this that I had worked on) Also replaced nearly all the capacitors on the board. NOAA weather channels with weather alert. Weight: 185 g (6.53 oz) Other features: CTCSS/PL & DTCS with tone scan. (Two R6/AA alkaline or NiCd/NiMH cells) or 6 VDC ±5 external: Current drain. Like you, I decided it must be a faulty transformer, so re-wound the one that fed the Drivers. Back to Icom Next receiver Last modified Icom IC-R5. gradually increasing as you went up from band to band.Ĭhecking the RF voltages with a probe at various places gave misleading results. All this combined with Icoms reputation of superior receiver performance at a reasonable price. I had a similar fault on my TS930S a while ago. Retaining the basic features of the very popular IC-R5, the IC-R6 features are further refined with a 100 channel / sec scanning speed, 1300 memory channels, 15 hours of continuous receive capability and voice control squelch. RX for ICOM IC-3J English language (IC-4) Low audio speaker mike on IC2A, 3A.
That is a very similar PA circuit to most Transistor rigs. English language (AT-160) Using the AT-160 with the IC-706MKII English.
