Anyone got a schematic of this #hp #84812a peak power sensor? The service manual I got has no schematic in it.🙃

In theory my #QTRigdoppler version should now be fully working with the #icom #ic9700 as well.
As I don't have one at hand, I'd love to get your feedback:

Two weeks ago I got this broken #HP8594 #spectrum #analyzer at #HAMRADIO fair in #Friedrichshafen
After a long night, multiple filter alignments and my own "interpretation" of the service manual, the unit is back alive⚡
Now I need a GPIB adapter & sig gen as well😝

Yes, use it or lose it.. every #hamradio Operator needs to act!🎙📡〰️📻 🛰 Get ready and send interference reports if you have them. Don't forget Bluewalker-3 and Bluebird 1-5, which are already transmitting on 430-440 MHz. Expect no help from anybody else than yourself!

I was looking for an #icom #IC2725 for quite some time. Got a very good deal on this broken unit🤑. Two new PNP transistors, some cleaning and new thermal paste later, it runs like on the first day😁

Had quite a bit of fun presenting our university radio club today.
Operating three radios at once turned out to be more challenging than expected!😝

Thanks to @2m0sql.com my #QTRigdoppler fork now supports Yaesu rotators and a websocket integration.

I added binaries so everyone using Linux can test it just by downloading and starting the app with their IC-910 or IC-9700.

Added a feature I miss on both of my #icom #ic910: Data VOX!
A small circuit triggers the PTT when audio from the computer is present. Added a switch as well to disable it😊
That will make life easier for datamodes on satellite😊

Got my first part from JLCCNC
A 250 Watt RF resistor case.
A nickel strip is used to connect to the N socket.
Usable up to 70cm. RL on 23cm is only 15 dB, Z matches the datasheet, so I guess the feed is fine and I need a better R
Tnx @carsten-oz9aar.bsky.social for your ideas😁✌️

Hey guys, do you know if anyone tried to line such photo light reflectors with wire mesh to use as antennas?
Anyone might have measured the actual deviation from a parabola shape?

Quick sunday repair of my #Alinco #DJ560
Two electrolytic caps on the AF PA were dead. ESR way over multiple hundred ohms.
Replaced them and the speaker regained its full volume once again😊

Just fixed the wording, of course apogee in this context is wrong. It is the height of the satellite at AOS/LOS times of an observer on earth.

Joshua|DL3JOP @dl3jop.bsky.social · Mar 22

Plot title is wrong, of course it isn't the satellites apogee in a given orbit, it is the max. height at my position over time. Bad choice of words on my end.
