Actually I had decided not to buy it. Then I discussed the matter with my good friend Takashi Kuroda who had bought one to replace his G31, and I decided to place an order at Grove Enterprises. The delivery time was a stunning seven (!) days.
I've just unpacked it and connected it to an aging dell laptop running a 2 GHz dual-core Intel T6400 CPU. Incidentally, the stated MSR is "2 GHz Dual Core"... I was pleasantly surprised to see that even at a 4 MHz sampling (and recording) rate, CPU load would not exceed 30 % (filter length set at 5000).
No antenna connected yet. I will go to Kongsfjord this afternoon. More as it happens.
