AO 91 Rumbling Noise
by Bernie and Cheryl 23 Jan '18

23 Jan '18

Dear Folks: Forgive me if someone has already discussed this, but I noticed a "rumbling" noise in the background during this morning's AO 91 pass. What is that? It almost sounds like a train is passing by. It was not dependent on someone transmitting as it was present even while there was no one speaking. But, it faded away as soon as the pass was over at my QTH. 73 de Bernie, KF0QS

Re: [amsat-bb] L-Band Equipment List
by Edward R Cole 23 Jan '18

23 Jan '18

Thanks for all the comments. Back in 1998 I bought the new FT-847 just before AO-40 launch. I was also getting into eme starting on 2m. The 847 worked very nice for satellite operation and eme and I kept it for 14 years. Note: I was AL7EB until 2005. But in 2010 I decided using a better HF radio with good transverters was a better way to do eme so I bought a K3 and DEMI transverters for 144/222/432/1296/3456. I already had a 10368/144 DEMI transverter. Subsequent to selling the FT-847 in 2012, I missed having full use of the 430-450 band and decided after quite a lot of searching new dual-band FM radios that finding a substitute for the old 847 made more sense. A local ham up here in AK had three FT-736R's so I convinced him to sell me one that had the basic VHF/UHF bands for $500. Interestingly, that got me a good old satellite radio in addition with all-mode on both bands. I had two other radios with 6m and transverters for 222 and 1296 so did not need to get those modules for the 736R. Since then I sold the DEMI 222/28 and bought a 222 30w FM transceiver (no SSB in use on 222 up here). My DEMI 432/28 has been idle with having the FT-736R. But it might still get some use as I installed dual LO's (locking PLL) to cover 432-434 and 435-437 MHz. I can do 144-MHz with the K3+DEMI or with my KX3-2M; probably use either on Rx and use the 736R with DEMI 144/1268 to Tx. But first step will be getting the 736R back on satellite U/V using my old AO-40 az-el tracking antennas. Probably get around to that in Feb. so you may hear another Alaskan on the sats "pretty soon". 73, Ed - KL7UW PS: I am on eme for 6m/2m/23cm and by next summer 9cm. Also collecting parts to do 3cm-eme (eme took over my interests after AO-40).

L-Band Equipment List
by Bill Acito 23 Jan '18

23 Jan '18

If someone puts this into a list, they should be very clear where a radio requires an optional module (e.g. The UT-10 for the TS-790 is nearly un-obtainium). Also, Didn't I see in passing that testing the L-band uplink indicated that the radios really should have 5khz tuning steps? Not all of these rigs can do that. Bill W1PA

Hi- I'm looking for ideas for wx proofing a tower mounted ant transfer relay for 1.2Ghz. I live in Washington, it rains here a "little". What have you done? 73 Bob W7LRD

Re: [amsat-bb] L-Band Equipment List
by Edward R Cole 22 Jan '18

I have one of the "rare" DEMI 144/1268 converters; does 15w out. Not many were made/sold before AO-40 crashed. Also a 45 loop-yagi for 1268. I have a venerable FT736R (with only 2m/70cm) for satellite operation (future). But if the mode will be LV (1268up/145dn) I will have to use a different radio for either uplink or downlink as the FT736R does not do in-band duplex on 144. I have two other radios that will do 2m allmode but it gets more complicated for tuning. FT736R has satellite mode for 2m/70cm (probably one of the first to do that). If the mode will be LU then all is fine. I also still have my mode-S preamp and two Drake downconverters if ever that band is reactivated. PS: not QRV on satellites (yet) 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa(a)gmail.com

L band transmit setup
by redski＠bellsouth.net 22 Jan '18

22 Jan '18

Can someone offer a little advice about the requirements for using the Fox L-band uplinks? I have an full duplex u/V and v/U satellite station so I'm guessing that my easiest route to L-band is an upconverter. But I've never used anything above UHF, so any thoughts on what might be needed to get started would be appreciated. 73, Red KC4LE
