I am not roving but I am determined to get back on 2 meters.  I have a coax issue. 432 is in fine business.

Anyone have plans yet for roving during the January contest?  I expect to be a bit more agile this time around, but haven't figured out where I'm going.  I'd be happy to coordinate to maximize grid coverage.

The water towers at that exit on I-25 are even better !

Bruce,

Ideally you'd want to go up to Magdalena Ridge. At 10,000 ft this is not a particularly good time to try that though, I can see the snow up there from town now. AA5PR ran from up there as a rover last June with WSJT. The DM63 line is just south of Socorro, the line runs just about through the landfill. If you take the old Hwy 1 south from Socorro, once you pass the landfill there are a couple of pullouts where one could set up. A bit farther south, without crossing I-25 on Hwy 1 but continuing south,you can access some open country, mostly BLM land with pretty good shots to the north and east. There's an old AT&T tower down there and the road turns west and rises into the foothills. Plenty of open space to operate.

West from here we do have the two ridges but I have been able to work AZ and southern CA with my 3 el and 100 wts pretty regularly.

Bruce, that would be great.  With that gear. you'll be loud.  I'm ready any time, but mornings before 10AM would be best for M/S.  There will probably be others that want to work you and I've put out some discreet inquiries on who needs the grid.

Re: Sunspot cycle 25 projected to look much like cycle 24

James Duffey
 

Yes, and this is a “consensus” prediction,  which considers predictions both large and small along with scientists that generated. Sort of prediction by committee. My simple model predicts a peak SSN of 113 +/- 27 peaking in March 2024 +/- 5 months. - Duffey

MINI CIRCUITS SAV-541+ pHEMT MMIC's for sale

Keith Morehouse
 

I have 10 extra pieces of this device for sale.

There is a minimum order direct from MCL of 20 pcs.  I bought the minimum but only need a few so I'd be happy to pass along the excess for what I paid - the 20 pc price of $1.55 each.  You pay cheapest shipping.

These are terrific low noise amplifiers with medium gain (18-20 dB) and super low (for MMIC's at least) noise figure of 0.3 dB below 1 GHz.  The devices are usable to 6 GHz.  Data sheet link is here:


The Ukrainian preamp manufacturer, VHF DESIGN, uses these in their "EME quality" 432 LNA.  I bought the MMIC's for spares...

For $50 more-or-less, this should be a super way to get your station set up for SO2R !

Bill,
I found more on the disappointing news you mentioned at breakfast. Attached a a PDF with details of the proposed loss of our 3 GHz allocation. If enacted, it might also have an adverse affect on other nearby amateur allocations, such as 5 GHz. Feel free to share/post the PDF.

TCXO's for 144 to 28 MHz transverters

Keith Morehouse
 

116 MHz sine-wave output TCXO
I have a pair of TCXO's that would make a good stable LO oscillator for 144 to 28 MHz transverters. They are spec'ed as being 0.3 PPM but they are from China, so who knows. I breadboarded one up and it appears to be pretty good. Nice clean sine wave (most of these you see for sale are square wave oscillators). They run on 3 to 5VDC and draw about 30 mA. They are in a 4-lead 16DIP package. They are right on frequency and put out somewhere between 3 to 5 dBm - I forget how much I measured.
I was going to use these to stabilize my DEMI 144-28 transverter but decided to go with the full-blown 10 MHz reference oscillator LO instead. I paid $24USD for the pair about 9 months ago and I haven't seen them available since then. (edited) 
If you're a decent experimenter, they shouldn't be too tough to use. Data sheet (what little there is of one) and my hand drawn schematic of the proper way to couple and bypass these things will be included.
Take them off my hands for $15 (for the pair) and I'll pay shipping in USA & VE (edited)
