My rig with 7" display is working ok for most part. (PA needs some tweaking) I have a 6" ribbon cable but it has ferrite sleeve. It was freezing up but that was several FW versions ago. I can try the

Would you like to test out one of these display drivers (FREE)…? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC

I have a v12 Main board where the 5-volt display works with a 3.5" cable but fails with a 5" cable.? I've done some experiments.? The display works if the ribbon cable wires are separated.? I've

Ok yep looking for someone that is using a short cable that can expand a bit to test this out. If all else fails, I’ll send one to Al, because I know he will be curious… Dr. William J. Schmidt -

That can work! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner – Operator Villa Grand Piton –

Wait a minute, Bill: my system at the present time does not freeze up, so that might not do you any good. Jack, W8TEE

I will have my 7" system ready in about 4 days, if that's quick enough. Jack, W8TEE

Hey for those that want boards, I'll be in town for about 5 days so now it the time to order. ALSO I'd like to get a couple of these display driver boards into peoples hands (yes, build and free) to

Well… Noise. Here are some things Oliver and I did with the T41 RF board to make the sensitivity and noise figure spectacular for the T41… 1. 4 layer board with V+ bus and GND inside to shield the

This is another update on my Tiny Ten transceiver, and particularly one trying to understand noise figure issues with the receiver side. ?I have done noise figure and distortion measurements and

Hardware was issue. I was testing 3rd party BPF that uses same bcd code as ours. Looking for short now. Tim

OKI-78SR-5/1.5-W36-C OKI-78SR-3.3/1.5-W36H-C They cost about $5 apiece. The 5V one is a direct drop-in. For the 3.3V one, you have to switch the wiring on two of the pins. Actually, you shift the

Something is wrong. The hardware is set up to select 17M and 10M differently. The truth table in in the design note directory, the I2C addresses document, the LPF tab. Dr. William J. Schmidt - K9HZ

Jerry, do you have the part numbers for the regulators that you used?

Yeah i wonder how that will go… particularly the price curve. Although the customs forms for CA were always a problem for shipping and that wont be a problem any longer. Dr. William J. Schmidt -

Tnx OM I will start checking! Tim

You can check the software to ensure that it didn't get messed up somehow. In BPF_Control.h, make sure that the definitions of the control words for those bands are OK: #define BPF_BAND_10M 0x0002

This needs to be verified with others, I get same BPF for 17 and 10M. 17M BP looks OK 10M it selects 17M filter bank. I was about to pull all the torroids off and start over, I had another BPF board
