What brand of mast mounted pre-amps are you using and do they sense RF for switching out of the feed line?

In my case I use the following for 144mhz & 432mhz, but because I run higher than 25 watts, I have the 160 watt units. 25 watt units are available. I use a Advanced Receiver Research mast mounted preamps at my station. 144mhz MSP144VDG-160432mhz MSP432VDG-160 Both units can be powered over coax if you order them with the optional bias choke. They are both capable of handling 160 watts and switch when they see arriving tx power. They make 25 watt units, also: msp-25 amateur | | | | | | | | | | | msp-25 amateur | | | | MSP28VDG-160 amateur | | | | | | | | | | | MSP28VDG-160 amateur | | | | On 1,296 (23cm) I am now using a SHF MVV-1296 SP23 23cm Masthead Preamplifier which does the same as the ARR units above and comes standard with the ability to go power over coax. It can handle 100 watts. https://www.thedxshop.com/sp23-23cm-masthead-preamplifier.html Steve NS3L

Hello Christy, Wish I could help, but nothing comes to mind. Are you using software to decode? Or a TNC? I can't tell for sure where you are seeing the text you reference.

help from WISP users. after about a week of normal operation on Falconsat 3, I started only seeing from Falconsat: one line of C0,C1,ETC CODE lines followed by the BRC data, then five lines of PHT data, then repeating. I suspect some WISP settings have changed. can someone point me in the right direction? thank you. Christy KB6LTY

Kantronics KPC-9612
by W2JV 18 Jan '18

Hello, I’m considering purchasing a Kantronics KPC- 9612 to use for Falconsat-3, is anyone using this unit for FS3 and is it plug-play? If anyone has used this unit in the past on older satellites with WISP I would also be interested in your comments, thank you. 73 Peter, W2JV --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

iCom-910h for sale
by Mvivona 18 Jan '18

In case anyone is interested, I put my iCom-910h up on eBay. It's a super clean one. I just haven't been active on the birds, so it made better sense to let someone else put this radio to better use than I. Michael KC4ZVA

Antenna coverage
by David Johnson 18 Jan '18

18 Jan '18

Hi, I am playing with a new feature that will be included into the FUNcube warehouse that is under development: Capturing the sub-sat point for each packet received so that I can get a rough picture of the coverage (this is from my turnstile without preamp). The site I'm using for ideas is: https://www.darrinward.com/lat-long I can get all your FUNcube sub-sat points from the database if you should be interested. I have a written a web service that will get the realtime position, which emits JSON: E.g.: http://satpredict.badgersoft.com/satellite/position/39444?latitude=52.4670&… <http://satpredict.badgersoft.com/satellite/position/39444?latitude=52.4670&…> {"latitude":"1.26","longitude":"158.76","altitude":"618.60","azimuth":"23.28","elevation":"-60.43","range":"11805.61","rangeRate":"-3.38"} - Dave, G4DPZ

PicSat demodulator?
by Ken Swaggart 17 Jan '18

17 Jan '18

Have been trying to decode the 435.525 MHz beacons from PicSat without success. The modulation is described as "GMSK modulation with G3RUH scrambling". I'm assuming the baud rate is 9600. Normally I use UZ7HO's High-Speed SoundModem for telemetry reception. Tnx, Ken, W7KKE
