Anyone know a way to get a small qty. of MAR-6 or MAR-7 devices?
I was going to try and roll my own version of the preamp circuit shown in the AMSAT store. I wish I had a spare 50 bucks to just buy one because I know it would go to help FOX but my money is extremely tight right now. Unfortunately when I go to the mini circuits site, I find that their minimum order is twenty and I'd be spending close to 25 or 30 bucks anyway. At that point, I would be better off buying the prebuilt amp if I could afford it! I'm trying to get back ito sats on a budget. I have a DVB-T stick and an omnidirectional scanner antenna that I'm experimenting with as a poor mans RX solution. I've been able to definitely hear transmissions but not make out anything legible from V0-52 and I've had no luck hearing S0-50 at all. Considering that I have about a 30 foot run of RG-6 quad shield from the antenna to the shack, I imagine that a preamp at the antenna would help and give me a definite yes or no if my RX experiment is even feasible. I am using SDR# right now because I find it easier but my eventual plan is to try and use HDSDR with the doppler being controlled by SatPC-32. I could go cheap handhelds and may eventually when I can afford them but given that I like to operate from my shack and not outdoors with handheld beams, I'll still need the preamp. 73, Michael, W4HIJ
Hi Michael, Check out Down East Microwave at www.downeastmicrowave.com. From the main page scroll down and click on catalog/Price List on the left. On the next page click on Our Online Catalog. On the left side of the page click on Components. Scroll down a bit to the MMIC section. They are selling MAR-6s for $2.20 a piece with no minimum. There are probably a few other components you can use in your project as well on their site. Their order process is a bit different than usual, but follow the instructions on their online order form and you'll be fine.
Hope this helps, -Zach, KJ4QLP
