single 8574 I2C expander gives You 8 inputs/outputs using NO arduino pins - only I2C. MAc mrn

Doc, I agree but a transistor and relay can't handle that! Raj

I would be interested in recommended android apps for audio spectrum analysis, there are lots out there but what is a good one (preferably free ?) God bless, Bill. G6ATO

That should be very easy. I’ll post what parts to change after some modeling but I’ll bet someone else will beat me to it! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ

Or... use I2C expanders where you can have 8 or 16 lines at a time for each address and use no digital outputs off the Raduino. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ

I took some time to measure the actual performance of my uBitx with its original calibration against a dummy load. The instruments used are not lab calibrated. I did check my wattmeter against my

Thank you for your interresiting. you remember the old mail. (I hope you bought a 3.5 inch LCD) I have been devoted to the wsjtx customizing work since last weekend. so I could not check the group

Henning, Yes that would have to be either byepaased or modded to handle upto say 55MHz regards sarma vu3zmv Regards MVS Sarma Henning-Christof.Weddig@...> wrote:

This an idea that some sketch writers might want to try. Example: Take three lines out to a BCD to decimal chip like a 4028 and get 8 outputs - you can switch that many output filters! 2 lines = 4

pleaqse think about the fact, that from the antenna input ot the first mixetr there is a lowpass fitler with a cut off at about 30 MHz, so receiving 50 MHz at whatever IF would need to circumverent

Hello group, I need help after spending over a week trying to figure out an issue I have with my uBitx.? First let me thank Farhan and team for such a great kit. I have built my uBitx around a

One of mine does contact the traces, as I happened to move the pcb, and could not work out what was going on. Then realised the heatsink was in contact with the trace below, mica washer for now

Ian, I received my next Raspberry Pi 3 and Touch Screen so I'm getting close to building one soon. I have to yet put together the interface ( I have a USB Digital Audio interface) so I think I only

Nick, When I get the positions finalized, I'll post my gerber files most likely, or at the very least, post the drill file. But not until I know they're correct... I'm building up the board now,

How you posted how to make and connect this yet? Can not seem to find it on your blog.

Anychance someone has these PIN outs/possition in gerber files? I would like to do my own full Mezanine board... 73, NIck

First world problems eh?

When it got beyond the Tek 2465, we'd roll over the cart with the Tek 7104, a 1ghz bandwidth analog scope with the micro-channel plate CRT. Could use it with a scope hood to see single shot events at

Datasheet for 86.85mhz SAW filter:??https://wireless.murata.com/RFM/data/px1002.pdf Here in the US, our FM broadcast band starts at 87.9mhz, at which point that SAW has 60 or 70dB of

Should be below the FM band in most (but not all) countries. Mike K5ESS Sent: Tuesday, January 23, 2018 8:02 PM To: [email protected] Subject: Re: [BITX20] #ubitx and 6 meters the murata
