Hello everybody. It would be useful to have an updated database of beacons in x-band, perhaps also divided by polarization even if I fear they are alone in LHCP.

Hello All – Looking for info [or where to find it online] about the Japanese Akatsuki spacecraft orbiting Venus. According to the latest “Sky &Telescope” which has a feature article about Venus the sp

Well I bit the bullet and ordered one of the new Kuhne 8.5 ghz downconverters today. Ive been struggling along trying to get what I have here working but have had quite a few issues so far. With the n

Hello amateur -DSN guys , Spending some times for to install the S band down converter + adequate VE4MA S band feed at the focus of the dish here . Not any problem for to detect the carrier of the Jam

Hi DSNers, Maybe someone is looking for USPR SDR with RX option covering S-band and below? Used, perfect condition: * USPR1 main board ( Product overview ( http://www.ettusresearch.com/wp-content/uplo

All, In case you may be interested, here is a link to a summary document for the laser rangefinder project I just completed to measure surface accuracy of the 4.6m parabolic dish I use for 8.4GHz obse

Thank you all for your kind words. I have posted a Rev. 1 to the link to replace the original document because I realized that my unfortunate use of the symbol theta in Eqns 10, 11, and 12 might cause

Has anyone looked at this new product from Kuhne: https://shop.kuhne-electronic.com/kuhne/en/shop/converter-transverte/low-noise-converter/KU+LNC+8085+C+PRO++Down+Converter/?card=2089? There is a revi

Hello All – I have so far spent a lot of money on two pre-amps for 8.4 GHz without success. Both oscillate rendering the noise fiqures [1 db & .8 db] useless. Someone within the DSN group made referen

All, This evening while observing the LUCY spacecraft near 8.445 GHz around 59630.90 MJD and wondering about the regularly spaced sub-carriers it is transmitting, I was surprised to see the main carri

I only had the 26GHz LNA/feed on the dish for a short time but here are a couple of plots from JWST as it was approaching the L2 point: JWST 25.9GHz It needed a lot of averaging to see the whole signa

Just a reminder: https://eyes.nasa.gov/dsn/dsn.html gives near real time status of DSN.. But more interesting is something like this: https://eyes.nasa.gov/dsn/data/1645458360.xml Which can be parsed

In case there is an interest in the report, attached is our detection of the OSIRIS-Rex spacecraft today while the NASA/JPL Goldstone DSS-14 dish (70m dia) was communicating with it. As the surface ac

Hi DSN A very interesting presentation from Daniel explaining how they detected the Voyager 1 signal using two antennas of the Allen Telescope Array in 2020. And also some demodulation experiments of

Hi all: I have been setting up my DSN System, with a solidd 1.4 m. dish, LNA mounted right at the primary feed + downconverter for the DSN X-band with a total eq. n/f of abt. 1.2 db. Sy/Cs is 7.0 db.
