Yes - challenges sourcing Generic parts seems to be emerging. I like the VHF multiband idea - and this may tie in with your Narrowband FM mod suggestion ... on the Raduino output! But somewhere

More like a multiband vhf... but it is not about any particular project. Radio community has inertia with favourite devices. While subsitutes are possible at low power levels, the devices are fewer

An all band SDR using a faster processor? Hi Hi M

A bunch of $3 Nano clones is a good choice. can hook them up to a few resistors plus some LED's and speakers and maybe a display, will make a great introduction to programming. If starting from

I just went through that due to a failing hard drive.? It was starting to drop sectors, but showed the problem as lockups when accessing various subsystems, such as serial ports.? Replaced the

I am trying to find transistors for our future work. The TDA2822 episode has had me hurting. It is time we identified some long term candidates for RF power. - f

So, exactly what math is this that was shown? Perhaps post 44560? Michael is only describing the conversion from 1'st IF to 2'ed IF, he's quite aware the uBitx is double conversion. Take a look at

DHL package showed up. Didn't open it up to inspect tda chip. Will post when I find out. Cory N7FV

Just ordered ten RD15HFV1’s from RF Parts. Considering how SLOOOOOWWWW their site is there must be a run on the RD’s ;-) . Mike K5ESS Sent: Wednesday, March 14, 2018 3:30 PM To:
