They have TERRIBLE supply chain and cloning issues and half the official resellers are shipping junk ones out. The fake ones used to fail cal but they now load in firmware which ignores that cal step :palm: :palm: :palm:. --- End quote --- Yep, That's why I just bought a DG8SAQ V3 VNA. SDRkits sell them but I picked up a used one on ebay. At £145 inc shipping it's more than a nanoVNA and does not have a screen but is a far better VNA. https://www.sdr-kits.net/introducing-DG8SAQ-VNWA3 In other news the internet and cable TV had been out from about 13:30 to 20:10 because some idiot dug up the fibre :palm: --- End quote --- Tempting. Dynamic range is better as well up to 90dB at under 100MHz. And 1Hz steps. Much better value for money. Only down side is it’s bloody windows based. Been there with the fibre cut :( |

The ugly duckling arrived today. It doesn't display anything but decimal points and an occasional dash, but DOES appear to be autoranging - when turned on then set to auto with no input, the decimal point steps to the left predictably as if it's incrementing down to the most sensitive range. Set to resistance, it displays a string of dashes which go away if the common and V-Ω terminals are shorted> This makes me suspect that it is actually measuring, but there are display issues as I suspect that the dashes are an overrrange indication in the resistance mode. More to come after I've had some time to dig into it. -Pat |

The first Volvo with a glued-in windscreen. We called it the racing footbath. If only the water hadn't always dripped onto the big PCB that carried the whole control electronics. In the end, I stood next to it on the town's busiest square, the car keys in my hand, while everything electric, pop-up headlights, wipers, windscreen washer, horn, you name it, was going on and off at 1 second intervals like a mad orchestrion. |

TR7: garage around it is more likely to get nicked. --- End quote --- There used to be a bloke, let's call him Morgan*, an ex-student from Brunel who had over the years made a habit of coming back at weekends to help out with the ticket office for Weekend gigs. As far as I can tell he'd been doing this since he graduated, either in the early years of the university or the late years of the technical college it grew out of. Morgan was in his mid to late fifties, ugly, moon faced, double chins beneath a receding chin, a conspicuous overbite, with horn rimmed glasses that had been out of fashion for 50 years, balding with a terrible comb-over, generally describable as greasy and sweaty. He wore checked jackets with a bad tie, over-tight collar and those shit brown polyester trousers that only existed in the 1970s and were four inches too short exposing argyle socks and brown suede Hush Puppies. He used to refer to any female students helping out as "his girls**" and against all reality gave every impression of thinking of himself as some sort of "lady's man". He used to drive a TR7, and when I see or think of a TR7 it's "Morgan" that I immediately think of. The direct relevance is that he used to park his TR7 on the road in front of the University, a place no one in their right mind parked as the mean "parking to theft" time there was on the order of 1 to 2 hours. Nobody ever touched it. * I don't know who I think I'm fooling by changing his name. Anyone who knew him will immediately recognise the description. ** He once made the mistake of describing my mate Caroline thusly within her hearing. The dressing down was something to hear, including phrases such as "impotent greasy old pervert". --- End quote --- When I think of TR7.... I think of rust falling on my feet while I drive, double-clutching the 2-3 shift or skipping it altogether because that's the only way to get to 4th. Ifni help you if you made the mistake of parking downhill with the car in reverse; it would take both feet on the clutch pedal (and this was in my youth, when I could leg press a even ton) to get the clutch to release so you could take it out of gear. mnem Still 10x the car as my Mk1 Capri, tho. :P |

I practically had to re-draw the entire side panel because it was all rubbed off. Not a good job I need to re-do it better. If you need any info from a working model let me know. |
