The best Audio Recorder is your ears, and a pen and a piece of paper :) But if you dont have one hand free you might be better off with some type of a inline audio recorder for sure! 73 Nick KE8AKW

OA4 on AO7
by The Romagni's 09 Apr '20

09 Apr '20

Hello all, I have spend my stay-at-home time hunting... OA4/XQ3SA has been very active on AO7... after 4 days yesterday finally got him, we have a very small window between EM55 and FH17; The old but trusted AO7 came thru for me. Looking at my records that is the longest qso so far I have done via the birds, around 3385 miles. He seem to have some local QRN, but he is there on almost every afternoon pass. 73 Steve W4DTA

Re: [amsat-bb] AO-7 and Move-11 - Move-11b

Hi,I noted the comments and reports regarding sources of signals being received whilst monitoring AO-7.I am located in Wales ( UK ) and use a simple "ELK " antenna and "Funcube" dongle for monitoringmany of the satellites.I can confirm that recently whilst monitoring I noted strong signals in the band with the software forFox satellites and others during pass times in the morning and late evening.I checked out both MOVE -11 ( Operates 145.950 Mhz ) and MOVE- 11b ( Operates 145.840 Mhz ). The signals were very strong and the Fox Telemetry software in auto late yesterday evening(8th April ) Move-11b on 145.840 and quite wide - It prevented the software from locking onto the Foxsatellite that I was tracking at times.Ken EatonGW1FKY

Rocket Lab Rocket Recovery test
by Wendy and Terry Osborne 08 Apr '20

08 Apr '20

Before New Zealand went into COVID-19 lockdown, the folks at Rocket Lab did a test to recover a first stage Electron rocket. You can see the video here: https://www.youtube.com/watch?v=N3CWGDhkmbs There are some other videos of the view from the rocket and inside the helicopter. 73, Terry Osborne ZL2BAC

M2 LEOpack tuning
by Mark D. Johns 08 Apr '20

08 Apr '20

I’ve had my LEOpack antennas about 8 years, but over the winter my station became almost totally deaf on 2 meters. I took the 2 meter beam down and cleaned up a bunch of corrosion around the coax connector, and that seems to have helped the situation, but... I checked the antenna with my MFJ Antenna Analyzer (which I did not have back when I first assembled these antennas) and find that the 2 meter beam is resonant at about 143.95 MHz — just below the 2 meter ham band. Up at 145.9, where I would LIKE it to be resonant, my SWR is about 2.5:1. Pretty high. Messing with the tuning sliders only made things worse (these adjust impedance and not necessarily resonance), so I’m wondering, has anyone else found it necessary to trim the elements on these? My calculations are that about 1/8” off each end of the DEs would bring it up the 2 MHz needed. Opinions? -- ***Sent from Gmail on iPhone*** Mark D.

odd phenomena AO7 ?
by Ron VE8RT 08 Apr '20

08 Apr '20

back in the late 80's and early 90's I'd heard this on the HF sats that downlinked on 10M, but not on 2M. While looking at future satellite plots I had the receiver tuned to the mid band of the AO7 downlink and I'm hearing CW (145.948 MHz). There are no amateur satellites above my horizon, anywhere. It was very clear, sounded like someone listening for their output, long dashes, bursts of CW, pauses, more of the same. I thought that I'd recorded it, but I didn't press the record button long enough and have nothing to show for it. GPredict, at about 21:12 UTC had the azimuth of AO7 at 327 deg with an elevation of -54. It lasted a few minutes and the followed the Doppler correction as shown on GPredict. When I pointed my antenna to the GPredict azimuth for AO7 the signal strength noticeably increased. Does this also happen on 2M? Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

IC-475H CI-V questions
by Ron VE8RT 07 Apr '20

07 Apr '20

I've recently came into an IC-475H that I'd like to use as the uplink on linear sats. But I'm having some trouble getting the CAT control to work. I'm using grig instead of going in/out of Gpredict just to test the CI-V link. I thought that this should work in grig: grig -m 307 -r /dev/ttyUSB1 -s 1200 -c 14 but it doesn't seem to connect. I have visually verified in the 475 the switch settings for the address and speed, they're set to default $14 1200 baud. With nothing connected the DC voltage on the remote output is about 2.0VDC which agrees with the schematic. I'm hoping that there is something I've overlooked. The interface with grig works with my IC-R7000 grig -m 340 -r /dev/ttyUSB1 -s 1200 -c 08 Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>
