o.k. I havent tried this yet do to the weather but after playing with some numbers, I found that if you subtract the high uplink freq from the high downlink freq and the same for the low frequencies, you get the same numbers. ie fo-29= 289.9 What is the relevance of this if any?

O.K. On a low elevation pass of Fo-29 I found a QSO on 435.845 upperside band using an indoor j-pole. Am I understanding correctly by assuming that the uplink was on lowerside band? And what was the uplink freq? Sorry for being ignorant but im having a hard time getting my head around this...

im wanting to try different sats and i dont unerstand linear transponder inverting ssb/cw.Fo-29 for example, how do you tx and rx? is it only cw or can you use phone voice? Please help thanks

Congradulations on the first SAT contact. I just pulled out my sat rig from its winter stowe. Waiting for some good weather. Hope to hear you on the birds. Just looked and dont have EM 95 yet 73 KB3TQO

Yeh ok, the reason I ask and this might seem stupid, is I would like to teather a balloon with a ht capable of crossband repeat strapped to it for the purpose of using low power to reach out further. I figure it would be worth trying anyway. As most of my radio use is portable, I could use my...

I was just checking this sat out on amsats site. I cant wait!!!!

are there any handhelds that are capable of crossband?

does anybody know if there is any free self study guides like the no nonsense guides for the updated tech class?

i also purchased this kit. so far the construction has been simple. i have found myself at a standstill with the connection between the board and the bnc connectors. the manual suggests using RG-174 but i dont have any nor do i plan on buying 1ft for 15 cents and spending $6.oo on shipping. i do...

oops i put this in the wrong location sorry. ive been interested in digital modes such as, psk31,sstv for a little while now and thought about constructing a homebrew soundcard interface. i stumbled upon this Interface Manual i dont know how to post links so sorry in...

WOW! the DK3 seems really cool. i coppied the parts list even though i dont fully understand it. im sure once i get started with the project, the smoke will clear a little. cool , thanks guys. it doesnt sound cheap but it beats spending $500.00 on a store bought screwdriver. i cant wait, gonna...

i just recently purchased the Arrow sat antenna, 3 element 2m/7 element 440

ive been hunting around on search engines and not really finding much as far as step by step building instructions. any help would be great. 160-10or even6m would be cool if its even possible. i live in an apt and i need an antenna for base, mobile and portable use. i know thats asking alot but...

ok!!!! i got away with putting satscape on the computer and im having all kinds of success. ive been making a few qso's on ao-51 and so-50. working satellites so far has been a little difficult as far as remembering call signs, it reminds me of flash cards from my childhood. what frequency steps...

ok. my girl friend has a huge problem with me downloading sat tracking software onto the computer. so i have been using amsat's pass prediction page along with the n2yo.com tracking page and im getting different pass times(about 45mins apart)between the two. my locations on both sites are the...

:pop: check out the iss fan club link in the 7th post, i dont know how to put links up or i would have done it here so, sorry.

been using the satellite maps at the top of this page i guess it was a glitch or something, it seems to be working now

why cant we track amsat echo or na1ss from the satellite maps anymore? im sorry, i miss worded that. im able to track them but i cant bring up any 5 day predictions. whats going on with that?

any suggestions for a dual band amp 2m/70cm w/preamp

currently i am using a 2 meter hand held as a base station and it would be nice to have a little extra punch. not only the extra punch, it would be nice to take some of the load off of the ht when trying to reach distant repeaters. long qso's tend to get the ht pretty warm when pushing 5 watts...
