Test Equipment / Re: B&K 2040 Repair video

Porkchop
The holder is HC-18/U. I cannot remember the load capacitance. I do have it written down somewhere. One thing we have done in the past is send the old crystal in and they can figure it out.


If you run across that load capacitance for the 10.243 MHz crystal please post it because I need to try to get one of those.  I have a 2040 that is off frequency and upon inspection of the crystals, I discovered that BOTH are 10.240 MHz in my unit (the one that should be 10.243 has obviously been replaced at some point with another 10.240 MHz crystal.

Hi Jon,
Glad you got that fixed. Those caps are always a problem.
Been really busy here myself.

As far as a DSO, I would get the Rigol 1054Z. A little more money but a great scope and hackable to 100MHz.
But I would also have an analog scope. Some digital scopes do not like RF.

Thanks for the kind words sonoma. Also good to see you. Where you hanging out these days?

radio Tech is good at repairing these scopes and other test equipment. a couple years ago my BK 2040 was acting up and just looked at one he had repaired and I was able to find a bad cap that was causing a problem and a few dirty contacts.

In this weeks video we take a look at the Sony CRF-V21 that was sent in for repair. We find circuit trace damage due to a previous bad repair.  We also take a look at the LCD to determine if it can be fixed or not.

Great video Buddy, nice to see the ole' girl come to life.  I like the use of the tape measure too, and great IRON base for the CW key.

In this weeks video we take a second look at the TX-1. What does it take to get an old transmitter back up and running? Stay tuned to see it come back to life.
