For the Dayton area guys, I will be headed down to Jeff's this coming Thursday, so if you want anything from him, work out the details with him and I'll be happy to haul it back up here, provided it fits in the back of the suburban. I'll have an empty seat or two if anyone wants to ride along. Leaving my place at 8 am.

A few minutes searching around minicircuits and this trio would go most of the way towards a 5.7603GHz CW beacon https://www.minicircuits.com/WebStore/dashboard.html?model=ROS-480%2B $25 (only available in 10 or more...someone probably resells it) https://www.minicircuits.com/WebStore/dashboard.html?model=ZX90-12-63-S%2B $50 https://www.minicircuits.com/WebStore/dashboard.html?model=JSW2-63DR%2B $4 (only available in 20 or more...find a reseller, or just keep the extras, who doesn't need some RF switches?) 386-480MHz oscillator, 12x multiplier (2.5-6GHz), and a fast RF switch for 5-6GHz. Throw in an arduino, probably a PA, and some glue components and it should be ready to plug-in and go. Trevor R.H.

Many years ago I built the original N1BWT (now W1GHZ) design for a 5760 MHz transverter. It used ratrace balanced mixers and pipe cap filters. He has since updated the design and uses a packaged Mini Circuits mixer. http://www.w1ghz.org/MBT/5760_MHz_Transverter_Update_March_2016.pdf This is very similar to the 10 GHz transverter he recently designed, which I just built. It appears to be an excellent performer. I would guess that this one is, too. (So was the original design.) The main difference between the 5760 and 10368 transverters is different sized pipe caps and different MMIC's. There are a lot of better performing MMIC's around than there were in the 1990's. The article shows the multiplier for the LO for the transverter. Paul supplies boards for both the LO multiplier and the transverter. I use a DigiLO for the LO source. The 1123.200 MHz output into the LO multiplier provides enough output for the mixer on the transverter board. Someone gave me a 5760 MHz amp because he didn't know what it was. I figured it out. It puts out 10 watts with 1 mW (0 dBm) input. I'm using a GaAsFET preamp. 73, Zack W9SZ On Fri, Jul 15, 2022 at 10:09 AM Trevor Clarke via mvus-list < mvus-list@lists.febo.com> wrote: > Anyone know if there's any weak signal activity on 5cm?
