On the 9700 I guess you’ve already checked that the rig’s attenuator is off and its internal preamps are turned on. The 9700 is especially deaf on 70 cm without its preamp. Also double check that the RF gain for the main band brings up the receiver noise floor at least a little when it’s up toward max on 70 cm. If no joy after the rig is set right, it points to a feedline issue. How is the 9700 connected to the LEO pack? Type, age, length of coax? Connector types? Two separate runs to the LEO pack? Etc. 73, RayKN2K

Were you listening in daytime or at night? Many times I have found after sunset there is little or no activity on satellites. Mid afternoon, on weekends, seems to be most active. If you hear beacon signals well, especially on XWs, your receiver is working. 73, Marshall AA0FO On Sat, Apr 17, 2021, 8:13 AM Bob Liddy (K8BL) k8bl@ameritech.net wrote:
Carl, Sorry to hear those results. You should have much better RX than that. Many folks on the BB have similar setups. Perhaps, the general AMSAT community can give more advice. GL/73, Bob K8BL

Bob: Here are my observations:Using both the AMSAT predictions and that from MacDoppler I tried hearing SO-50 at 12:59 4/17 on a 13 minute pass. Both AMSAT and MacDoppler compared favorably. The D72 and GP-95 could hear only faintly. The 9700 and the M2 LEO Pack antenna barely copied but when I switched to my long-boom 70-cm yagii fed with 7/8” helix I I got about a S-6 signal and could see it on the scope. Duringthe pass I heard no stations calling or in QSO. Certainly polarizations were not helping but I was really disappointed. Path losses according to MacDoppler are high - in the area of -150 to -160. Thoughts? 73Carl WA0CQG

Some of them are quite strong and folks have heardthem with handhelds and worked them from mobiles using verticalantennas while in motion. Since moving to a new QTH, I have no home station at the moment.But when I'm roving and using an Arrow, the SATs are easy to hearand track. I use either AmsatDroid or Look4Sat on my phone and theyboth do a great job. If I were you and I just wanted to check if I could hear a SAT, here'swhat I would do. Pick a common SAT known to be active and well-usedlike SO-50. Set your RX VFO to 436.800 MHz FM. Set your antennaelevation to about 20 degrees. Look up the timing of a pass viewablefrom your location. Set the azimuth of your antenna in the direction ofthe middle time of that pass. At that time, you should hear SO-50 loudand clear with several stations making QSOs. Since you say that your setup works fine for terrestrial QSOs, you willsurely hear SO-50 if you have the pass time correct for your location andyou have the azimuth set properly. If you want to verify that your MACsoftware is accurate, check the pass info against the AMSAT predictioncalculation for your QTH on: AMSAT - AMSAT Online Satellite Pass Predictions

Bob - Thanks for your input. Right now I am using a TH-D72 handheld and GP-95 vertical and also the IC-9700 with the M2 LEO Pack. I hear nothing with either although terrestrial reception with both is fine. I am using MacDoppler software for tracking and have verified time and location. 73Carl WA0CQG

The FM SATS are pretty easy and can be loads of fun. However, beingso easy, they get quite busy at times which brings about mayhem andchaos. It takes a while for new users to learn the proper operationalskills for using a single channel repeater available often nationwide. The Linear SATS are somewhat difficult to master at first, but most folkscatch on in a reasonable timeframe. They have a wide bandwidth whichmakes them available for quite a few QSOs to take place simultaneously.And, they can be actual QSOs as opposed to hello/goodbye types thatare the norm on the FM Birds. Your 9700 is an excellent radio for theLinear SATs, whereas an HT would have been sufficient for the FM ones. GL/73, Bob K8BL

What handful of Amateur Radio satellites should a newcomer focus on? The Amsat Current Status table lists 15 with current reports but many of those are telemetry only. Is there a current “Amateur Satellite Frequency Guide? My April 2019 is pretty out of date. I need to know what satellites I should try to hear in an effort to validate my IC-9700 and M2 Leo Pack system. 73Carl WA0CQG -----------------------------------------------------------
