Suitable N Connectors for Gore PhaseFlex RF Cable
Anyone have any experience modifying/repairing Gore PhaseFlex cables?? I have a couple of long (25 ft) Gore cables, unfortunately terminated with TNC connectors, that I found fairly cheap. They are

Re: Panel mount scheme for 128 x 32 0.91" OLED?
Thanks for the suggestions.? I don't have a 3D printer, something to investigate in the winter months perhaps. My solution:? a 36 x 21mm? piece of 1.6mm PCB with a hole cut to just clear the edges

Remove the standard header and solder a surface mount header through the front passing the pins through the board to the rear then design a small circuit board with a cutout for the display that has

Re: Heterodyne RF generator
I've been reading the ADF4351 datasheet and app notes and cannot figure out if one can sweep one output while holding the other constant. Does anyone know from experience? My impression from the

Re: Heterodyne RF generator
If you can get bidirectional access to both the RF and IF ports of the mixers the Jerrold cable box may be your best option

Re: Heterodyne RF generator
As the variable frequency range will probably be less than from the fundamental to close to the second harmonic I'm not sure injection locking will be a problem. It may required some "pulling" to move

Re: Heterodyne RF generator
I haven¡¯t followed this thread closely, so I apologize if the NE/SA602 has already been discussed. Depending on your ambitions for performance, basing a heterodyne sig gen on that venerable part

Re: Heterodyne RF generator
No worries. Figure things out and let me know what to do at my end. When is your birthday? My tinyPFA came today. Time to test my Chinese OXCOs :-)

This is what I did before building the tinySA Build two single transistor oscillators, one on fixed 100MHz and other variable 100MHz to 200 MHz using a varicap Triangle steering of the varicap done

Quick reply: please wait a little, I am consulting a couple groups on how to send it, otherwise there is the risk of Customs charging in the order of its cost. What is your idea, e.g. FedEx, USPS,

Daniel, I need your mailing address! I'm not licensed so I can't look up your address on the call lists. I hope to correct that soon, but am too busy playing with other toys. I intend to send a pair

Re: Panel mount scheme for 128 x 32 0.91" OLED?
I haven't had to do that, but have mounted the 0.96 and 1.3 inch displays on standoffs (2.5mm works well).? If the 0.91 display is behind plastic, then I'd 3D print a small holder to back it up. I'd

Re: SCPI Command Parser Firmware For Instrument
SCPI syntax appears very simple, not need for lex and yacc. An ad-hoc lexical analyzer and parser would probably more simple and eficient. But indeed, it's very surprising there's not an already open

Re: Panel mount scheme for 128 x 32 0.91" OLED?
You might try one of the 3D search sites (yeggi/thingiverse) and find something that uses one, and steal a 3D printed mounting technique from it... IIRC, I think those OLED's are sometimes used in the
