Hi all, It would be great to have a multiplier that /P stations can use, unfortunately its not just a case of wandering into the shack and pressing the go button to establish a station up on a hill.

Hi John, Im sure they were in equipment I used to work on years ago, made by SIAE. Might be a "C" number on the PCB or metal that would help identify it.. In the equipment I saw it in, it was used

Hopefully someone locally does, but as a backup plan I have Male, Female, and Sexless versions out of old HP Spar test sets. Kent

I'm looking for a chassis mount APC7 connector. Something like https://www.surplussales.com/Connectors/APC.html but I am not paying their asking price. Or does anyone have an APC7 to waveguide

Yep.....done some prodding around on the switch and the feedthrough from the PCB in to the body of the switch seems to have back to back diodes to ground and applying either + or - 0.7V to the feed

I would think, purely based on "seat of the pants" hunches that with an isolator of that sort of size, it would be intended to work at the "couple of watts" level. I agree, it is likely to be a PIN

Hello Microwavers of the world Attached are two photos of a wr42 waveguide switch with attached isolator I've very kindly been given. Look carefully at the close up and you'll see that the guide has

Looking at my uploads I can see that OpenSky seemed to be down between 07.00 – 08.00 utc this morning It appears to be back online at present, but is very (that is VERY) slow to respond. I

Airscout was working yesterday morning, but not today. Anyone have any updates? David, G4YTL

Hi all , after the successfull activity from IN87 , I will be ,on the coming tuesday , in the afternoon ( approx 16loc up to 19h30) in JO10 with 6/3 and 1.2cm). 73 de Dom F6DRO/P

If anyone is interested. OpenSky is back up and running this Sunday morning. Looking at my uploads to the system, something was reset between 07.00 – 07.20 utc this morning. I haven’t checked

More good rainscatter reception this morning with signals received over a 60 degree beam heading 300-360 from IO80KX

The data I have says 18GHz and 3mm male see attached, the 7618E (15dB ENR) has a precision SMA male. The data differentiates the SMA and 3mm male quite clearly. 73 Conrad PA5Y From:

Hi Conrad, That it is one of the best, probably the best ! I use this type of adapter for my NF measurements. 73, Sylvain F6CIS HP/Agilent 1250-1744 18GHz 3.5mm-Female / N-Male Precision Adapter

A reminder that the 2022 GM Microwave Round Table will be held on Saturday 22 October in the Museum of Communication in Burntisland, Fife. Full details are at https://www.gmroundtable.org.uk/ . I am

Hi, my datasheet says 1-18GHz and SMA. 73, Rainer Am 03.09.2022 um 09:41 schrieb f1ghb:

Hello, What is the max frequency of the 7618EL ? I saw a 7618 with a maximum frequency of 18 Ghz, the connector is SMA Let say if the EL version has a max frequency

I am expecting the delivery of an Ailtech 7618EL noise source early next week. It is a nominal 6dB ENR source, and the datasheet lists the output connector as a 3mm male. Is this likely to be a 2.92mm

The OpenSky API server is returning an error at present, so there are no working plane feeds on Airscout right now. I haven't had time to get my ADS-B receive antenna up high yet, but

Small patch of rain now in Camarthen Bay and the signal is coming in a good S5 RS ..10 degrees off heading over to the west A
