HO -68 FM transponder Activiation

The AMSAT - China (CAMSAT) website giving details of the various activations (Click Here) for HOPE OSCAR (HO)-68 indicates the until the 25th April, 2010,  the activiations will be mostly on SSB/CW. 

But there is an activation favorable to Indian Satellite enthusiasts having only FM setup, on  April, 25 2010 at 09.02 IST (0332 UTC) when there is an activation on FM.

It is a favourable elevation of 33 Deg (with respect to Bangalore) coming from North to South in the Eastern Horizon.

Hope to work some DX during that pass.

OSCAR QSO update for 18/04/2010

The sunday morning is generally reserved for my satellite QSOs. It was a good day to being with, there were three satellite passes starting from 9:06am (IST).

HO-68: copied E21EJC 5/6, however could not complete the QSO with the station.; self voice received through satellite.
SO-50: copied VU2SWG; self voice received through satellite.
VO-52: no stations copied but the self voice received through satellite
.

Curious day as despite of a 50+ degrees pass at Navi Mumbai, did not copy any VU stations.

HO-68 Possible Passes with FM Activiation

HO -68 (XW-1) will be active on FM with the following sked (Peak Elevation w.r.t. Bangalore)

16.04.10 - 08:02  IST - Peak Elev 05 Deg
17.04.10 - 07:48  IST - Peak Elev 01 Deg
18.04.10 - 09:12  IST - Peak Elev 41 Deg

These passes are all on the Eastern side of VU-land.  Therefore, stations on the eastern side of Bangalore will have a better elevation angle.

The 18th April Pass seems to be very good as the footprint of the satellite is very wide.  There is possiblility of stations from south, south east and even Far East to come thorough.  Let us give it a GO.

as a reminder - the frequencies to us
TX on 145.825 - 67 Hz CTCSS tone
RX on 435.675 +/- doppler shift (scan on the lower side to begin with and go up as the satellite moves)

WOUXUN - KG-UVD1P - Dual Band Handheld

There has been a lot of interest lately about the China Made - Dual Band handheld transceiver range from WOUXUN.

My personal experience with WOUXUN - KG-UVD1P - is 5 star. As already mentioned elsewhere, the rx sensitivity is really good. Of course the S- Meter is really generous - more of guess meter than a S meter - but as we hams always say - "your report is ___by the EAR" - not a problem at all.


The accompanying manual is the usual "Chinese English" - It takes a little time before you comprehend what exactly it means - but do we hams really use/need the Operating Manual ???????

The antenna connector is a little tricky - SMA Male is on the rig - you need a SMA female connector if you are connecting an external antenna - easily available in SP Road, Bangalore for around Rs. 350.

The speaker mic that is available as an accessory is really FB - excellent audio report - also compatible with Kenwood handies.

The other accessory - the ear phone mic - on similar lines with the mobile phone ear-set - is equally sensitive and has a good voice pickup range - listeners have not complained about the audio level even when I accidentally talk from behind the mic.

The Battery adapter design is the only drawback - the wire comes from under the pack - a stand has to be used or designed to take care of that.

Just a few comments - But I find it worth every Rupee spent on the rig - Am having a BALL using this for my Satellite QSOs. Those of you who decide on this equipment - WELCOME ABOARD

The following the text of the email received from VU3VOC

Please find attached an image which i processed using wxtoimg software

The signals faded when the elevation was around 5.5 deg. Frequency was
137.5 Mhz.
India looked very beautiful. One can even see the Adams Bridge near Rameswaram.
