Hearing AO-85 with a KG-UV9D & dual-band duckie

by Patrick STODDARD (WD9EWK/VA7EWK)

Hi! After seeing several people at my demonstration in Goodyear AZ last week used their HTs with standard duckie antennas to hear AO-85 as it passed by, and seeing many positive comments on how easy it is to hear this downlink, I decided to try it for myself. On my way to the office this morning, I stopped at a shopping center parking lot for the AO-85 pass around 1438 UTC to hear this pass. AO-85 went up to a maximum elevation of 41 degrees, which would have been a nice pass to work if I had my Elk log periodic in the car. After about 3 minutes into the pass, I could hear the round- table conversation taking place. Using my Wouxun KG-UV9D HT and a Nagoya NA-701 2m/70cm duckie antenna that is about 8.5 inches/22cm long, and with the squelch open, I was able to listen to the downlink. I had to move the HT around while listening to the downlink, but I was hearing it. I had the HT in narrow FM, as I described in my report on working stations via AO-85 using this HT and my Elk log periodic antenna I sent to the -BB yesterday. I had to adjust the frequency down from 145.980 MHz through 145.9775 MHz to 145.975 MHz near the end of the pass, using one of the HT's VFOs. While I was listening to this pass, I used my mobile phone to make a short video clip of what I was doing. The 4-minute clip I recorded around the middle of the pass is now on YouTube at: https://www.youtube.com/watch?v=OZDpRZHd2FE There is a point in this video clip where I was not hearing the downlink, as I dropped the radio into my car. Once I picked it up and held it outside the car again, I was able to continue hearing the downlink. This is not a professional- grade video (it was recorded in 720p, but I'm not a movie producer), but it shows that we don't need much to hear AO-85. During this pass, I heard several stations, and the video clip has most of them. I was hearing WA6DIR in California, KC7MG in Arizona, AA5PK in Texas, W7SXM in Washington state, and late in the pass I heard KC9ELU in Indiana. If I had planned this out better, I would have tried to record more of the pass, and made sure I didn't drop the radio during the recording. Happy Thanksgiving, and 73!

Heavens Above Tracking Program

by Ed Cunningham

I started working satellites in April of this year and have been using Heavens Above to track ISS, SO-50 and AO-85. Because of my location (my back yard) SO-50 has not been in a good position during the day for me to work. I have been trying to work AO-85 but have not heard it for the past week. I initially thought that the antenna had a problem but it wasn't since I could hear conversations on various repeaters in the Phoenix AZ area. This morning it downed on me to check AmsatDroid Free on my phone. I found that the information on passes listed on Heavens Above was early, the LOS time was actually the AOS time on AmstatDroid Free. I have been setting up for a pass and getting on early using the Heavens Above information and getting off just as AO-85 was reaching AOS. Up until this past week Heavens Above has been very reliable. Both the Android phone version and the internet software version are giving the same pass times. Using the pass times from AmsatDroid Free I was able to hear conversations on AO-85 this morning but was unable to make contact. That's me being new to AO-85 which, I have read, can be frustrating. 73, Ed, N7EC

Re: [amsat-bb] AO-7 transponder pan view

by Eduardo Erlemann

It is a SNR (signal to noise ratio) matter, if you position your TX on the top of the hill you can hear it stronger but the noise is also stronger, if you slip to the mid of the valley your signal will be weaker but noise as well. In a practical experiment (using my ears) I noticed a better SNR relationship staying in between the valley and the hill, which will be very difficult to find for who uses a regular rig for RX. 73 Ed PY2RN GG66LW -------------------------------------------- On Wed, 11/25/15, Joe <nss(a)mwt.net> wrote: Subject: Re: [amsat-bb] AO-7 transponder pan view To: "Eduardo Erlemann" <sasb.geo(a)yahoo.com>, amsat-bb(a)amsat.org Date: Wednesday, November 25, 2015, 1:25 PM So, For best results you want to place your signal in the valleys true?

I think it is caused due the components age/conditions which is affecting its receiver linearity, noticed even in a such narrow band. 73s Ed PY2RN GG66LW -------------------------------------------- On Wed, 11/25/15, Joe <nss(a)mwt.net> wrote: Subject: Re: [amsat-bb] AO-7 transponder pan view To: amsat-bb(a)amsat.org Date: Wednesday, November 25, 2015, 12:08 PM Thats pretty cool.

AO-7 transponder pan view

by Eduardo Erlemann

Panoramic view of AO-7 transponder, using FCDP+ for RX and TS-2000 for TX. I got late on he bird after 1/2 pass that started at 18:40 UTC, forgot to swap SDR# IQ in the first moment :( Max elevation was 64deg TX power 5 Watts all the time and RHCP most of the time. About 2 min before end of recording it is possible to hear I think a CU station calling. https://www.youtube.com/watch?v=jCq0WaEZ9g8&feature=youtu.be 73 Ed PY2RN GG66LW

SAT work with FLEX radio

by David

Hi all and Happy Thanksgiving, Question.. how many of you are doing SAT work with a FLEX-6000 series rig? I'm in the processes of pursuing just that, got my first Transverter to build, while I'm waiting figured I'd start the conversation on how do you have everything setup? I had a 9100 and could do full duplex and am wondering if the FLEX with transverters will allow the same full duplex operation (I'm assuming it will) Keep in mind here I am new to this transverter thing and have never set one up before.. Thanks David

Travel Day mobile QSOs

by Robert Bruninga

Ham Radio Travel day: Don’t forget to monitor 144.39 with CTCSS 100 and get automatic alerts (pings) when you are in mobile simplex range of another mobile traveler (running APRS). It works with ANY mobile radio. As long as you have CTCSS set to 100. It is better than CQ 52 because the other mobiles are sending out a ping once a minute instead of an occasional CQ call on 52. With cars passing each other at a combined 120 MPH, you are only in range of each other for a few minutes. So, you can either call CQ every 2 minutes all day long, or you can sit back and monitor 144.39 with CTCSS 100 and let the radio do the work. For more info, see http://aprs.org/VoiceAlert3.html Happy Travels. Bob, WB4APR
