Problem with Juma Shop

Been looking at the online juma store and there is a lot of out of stock items.
Also, it looks like the site might have been hacked. Can someone look into it?
I wonder what the future has in store for this great line of ham gear. Is the end near?

I found the N3ZI dds vfo and the mpu/ dds board is the same size of the receiver board, a perfect match. It works just great. Now, I need to figure how to make band pass filter switc...

Re: PA100-D Chip identification

Look for one side that is beveled. With the beveled side facing you, the left side is pin one.

Re: potential builder questions

I really like sdr-radio with my fifi. I also tried it with the trx2a. I had to fool the software into believing the sdr radio had a SI-570 by plugging a soft rock into a USB port.
