I own a 8618B receiver I bought for 800 dollars on eBay. It needed repairing and Steve Pappin made it like new. It is by a bit the most sensitive receiver I have ever used for VHF UHF. More than my ICOM R9000 and that's saying something. My Watkins Johnson 8618B is the best but it needs forced air cooling and rack mounting for ventilation. No intermod either.
