Try an AEA VIA Echo. A lot more than the MFJ but worth it.

You can guess my answer...
Yes :)
We make every attempt to keep the digipeater ON when the BBS is on. In fact, I think the default from a full reload of the satellite is DIGI ON.

It is definitely harder to access on the L uplink than on the rarely used V uplink, but it does work.

Hi Howard I wouldn't be without my MFJ-269 analyzer.? It is very accurate and a handy size.? Highly recommended. (no, I don't own stock in MFJ) One word of caution: mine (and maybe there is something wrong with mine) draws some power from the batteries with the power switch OFF. So I take one of the batteries out when not in use.

Hello to everyone I am seriously thinking about buying an antenna analyzer,I build enough antennas to justify buying one.I enjoy building HF,VHF,UHF antennas of all flavors.The standard swr bridge is just not cutting it anymore.So I guess what I am looking for is one that will do 3mhz to 500mhz,nice to have computer interface but not a priority.I have seen a few on the internet but its nice to get some user input,rather then the sales pitches.

Hello group, after finally getting my SSB part of the station fully operational, I then moved on to getting my packet operations up and running , and with great success, one wee problem, I have noticed this when tracking the ISS, I am able to still digipeat off the station even long after it is supposed to be beyond the horizon according to my Satpc32 ISS software. My keps are up to date via the Satpc32 software, is there a error due to the large amount of mass now docked on the ISS? or have the keps not be uploaded in a timely fashion to the server I get my keps from?...
Run down of my operation conditions here are as follows...
Radio - Kenwood TS2000 Software SATPC32 + Satpc32 ISS PC - Dell P4 2.4Ghz CPU with internet connection
Is there another method of getting my keps to show more accurate tracking of this big bird?...
Regards,
Marc Tessier - VE3TES [email protected] Grid FN25pa

Hi Pete, WA6WOA
I do not recommend the MFJ-269 antenna analyser because it is very inaccurate particularly on 435 MHz I have compared the MFJ-269 with several professional network analysers and I have found that at most the MFJ is usable up to 30 MHz maximum because above 30 MHz the inaccuracy on the real part and the imaginary part of the impedance reading becomes absolutely unacceptable.
My MFJ-269 was purchased as new but connecting to it a professional 50 ohm termination good up to 12 GHz the VSWR shown at 435 MHz was 1.1
I have sent back my MFJ to the factory for inspecting and calibration but I belive that the above instrument was a very bad affair for me and will be a bad affair for all that intend to use the analyser above 30 MHz.
Be happy with your MFJ-269 even if dreaming while sleeping I am sure that my message made you suspect a wrong real part and a wrong imaginary part on your impedance reading !

Domenico,
For most Amateur Radio work a VSWR of 1.5:1 is adequate. I personally have never expected MFJ products to be in the League of Anristu, HP and Rohde and Swartz. MFJ is a yard stick, the others are a micrometers Art, KC6UQH -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of i8cvs Sent: Sunday, March 06, 2011 9:41 AM To: Pete Rowe; AMSAT BB; Howard Kowall Subject: [amsat-bb] Re: Antenna Analyzer

Thanks Dominico I have also compared my unit with an HP network analyzer and have found the readings to be quite acceptable for amateur work.?? Mine reads 1.0 :1 into a precision load up to 170 MHz.? Indeed, it reads 1.1:1 at UHF and that is just fine for my measurements. Rarely do I see an antenna match less than 1.1:1.
