Digital Multimeters

I wrote about receiving the VC-1008, the new multimeter in my shack.
Well, I told you that I have a very old DMM, a Voltcraft VC98 with 3 and 1/2 digits.
I bought it from my first wage, back in 1995 and was around 200 USD at that time. A lot of money!
I never succeded in my trial to make him communicate with my PC via IR...
It has no autorange, the selector is a pain in the a&*^&* but it works! Yes, it works perfect and even has a bargraph wich is very nice. It's a backup DMM in my shack.

The other one is also a Voltcraft, a VC-960, top of the DMM in 2011 if I remember right... Have some issues with it but manage to make it back in service. At least at 90% (still have some problems with AC current measurements).


Here are some pictures:

Greed-O-Meter

Well, "Greed Deep-meter" is not  tthe correct form!
"Greedometer" or "Greed-o-meter" seems more appropriate to me.

Greedy hams!

A new multimeter in the shack.

Since 1996 I am a fan of Voltcraft multimeters. The first one was a VC98. It still work altough is heavy modified to overpass the years. It is not very precise and has a little problem with the rotary selector but still in service.

The second one is younger but I managed to fry it a little. It is a VC 960. I love it, especially for the 200 Mhz f-meter and the 5 digit measurement capability. Not in production anymore and I couldn't find one from a good seller.

So, I ordered from Conrad a VC1008. 

First impression is positive. It already has the external power connector and it works with 4 AA batteries that can be rechargeable ones.

The case feels a little cheaper than the VC960 and the max. freq. is only 8 MHz.

Another positive is that the optical USB interface and the software are included. For the VC960 I had to purchase the optional interface.

I found the schematic for my VC960 and I will try to make it work again.
Happy Birthday to Me!

Extreme unpolite station...

While I was trying to call a station from Mauritius, an Italian station started the transmission below:

Of course, 3B8FA wasn't on air when the italian station finished the unwanted QSO.
No, I do not logged that!

First day...

Well... wednesday early morning I had a heart attack. Fortunately, my wife was awake and knew the sympthoms so the emergency crew from the ambulance already had their emkit when arrived. I was at the hospital in less than an hour so I may say I am a lucky one...
But all my life has changed in these few days...
I feel that I must change the priorities so, there will be less posts on this blog.
Wednesday 11th of June was the first day of my remaining life...
