Portable activity tomorrow

Post by g8gtz » Mon Apr 05, 2021 7:30 am

Dave G8GKQ and I are venturing out for our first /p expedition tomorrow (Tuesday 6th April) - nothing exciting but will be very good to get out :D

I will be at IO91JH (Hannington) near Newbury and Dave will be at IO91EB (Dean Hill) near Salisbury.

Bands will be 146 DATV, 5665 FM and 5761.5 DATV - talkback on 144.750 vertical.

Be good if anyone else can join us.

How are you generating DATV on 5.7? IIRC the Pluto DATV software had a 32bit overflow that was limiting its top end above 4.3GHz.....
SLight chance of being able to go out /P for at least 2M RX....timings dependant....

Perhaps at 144/435 with a transverter ? That's the usual way.

Hi

I hope to be set up and ready to operate between 2:30 and 3 pm (Tuesday 5 April). Exact location will be IO91EA27.

My 5.7 GHz DATV is from a single/double conversion homebrew transverter. The first LO is 4.2 GHz giving me a first IF of 1560 MHz. I use this for DATV transmit from a LimeSDR, and DATV receive with a MiniTiouner. The second LO is 1130 MHz giving a 430 MHz second IF to use with an FT-790 for SSB and NBFM. Design choices driven by filters from the junk box and the upper frequency limit of the ADF4351 first LO.

The PA and preamp can be switched to the WBFM analog ATV drone kit in the same box. About 10W output on both 5.6 and 5.7 GHz.

Dave, G8GKQ

I'll be swinging the 2m around tomorrow chaps and listening VP on 144.750. Will you be using DVB-S or T on 2m?

Have fun and I hope to see/hear something from one or both of you.

Still a slight chance of me making it out to play on RX, subject to trains and pickup times. Just managed to TX 'cross-town' on 70cms with Justin with a bit spare, co-linear to colinear. Nokia Dolphin amp this end.

Just remembered my car has its MOT this afternoon but I should be back by 3pm.

My locator, should you wish to point my way, is IO91WI14.

Currently monitoring 146.5 MHz - 333kS, DVB-S2 on a heading of 252 degrees and 144.750 vertical FM.

Cheers,

Martin

I will try to get out to IO91SF with 146 receive only. Should be a good path to Noel but not so good to Dave.
