Yes, TX Factor episode 21 is finally available and features a review of the IC-7610 transceiver from Icom. Bob shows Mike a thing or two about operating thorough linear satellites. And, have you ever worried about programming your DMR handie to cope with code plugs, gateways and chatrooms? Again, Bob thinks he has the answer.

In our free-to-enter draw we have another two prize give-away: a Prism padded dust cover for your rig and a copy of Andrew Barron’s book Hamsats and Amsats.

It’s all at www.txfactor.co.uk

Happy viewing!

Welcome to Episode 230 of Linux in the Ham Shack. We're freshly back from Hamvention 2018 and ready to roll. In this episode, we do a deep dive into the FlexRadio SDR platform. We have two interviews recorded live from Hamvention all about the Flex architecture, its Linux and Open Source roots and much more. We would like to thank Steve, AI4QR, and Steve, N5AC, for spending some time with us to let us all know about the future of software-defined radio servers.

Here is this week’s space weather and geophysical report, issued 2018 May 28 0238 UTC.

Highlights of Solar and Geomagnetic Activity 21 – 27 May 2018

Solar activity reached low levels during the period due to an isolated C-class event, a C2 flare from Region 2712 (N13, L=172, class/area Csp/80 on 24 May). No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 21-27 May.

Geomagnetic field activity was quiet to unsettled on 23 May due to influence from a positive polarity, coronal hole high-speed stream (CH HSS). Quiet conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 28 May – 23 June 2018

Solar activity is expected to be very low throughout the period, with a slight chance for isolated C-class events on 28 May – 04 Jun and 10-23 Jun, due to flare potential from Regions 2711 (N06, L=288, class/area Cai/60 on 24 May) and 2712.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach very high levels on 05-07 Jun with high levels expected on 02-04 Jun and 08-13 Jun. Moderate flux levels are expected for the remainder of the period.

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 02 Jun with active levels on 01, and 03-04 Jun due to the influence of a recurrent, negative polarity CH HSS. Unsettled levels are expected on 28-29 May and 05-06, 13, 19 Jun. Quiet conditions are expected during the remainder of the outlook period.

When HF Signals marketed the uBITX early December 2017, customers leapt in and ripped them off the shelf. Who could imagine the small Test facility in India that VU2ESE had setup trying to cope with the unexpected demand, or the women having to wind and test the toroids, churning them out at speed without breaking a finger nail. Even one type of toroid used had to be subsituted, for another, as the world ran out and they couldn't be sourced easily, but still the uBITX somehow was kept on track. A total to date of over 6000 uBITX PCBs sold, with very few bugs reported, apart from one batch with the faulty WX branded TDA2822 audio amp that hit the fan and must of caused an awful headache at the time.

Now that manufacturing has now caught up with demand, and there is no time lag on ordering, the uBITX becomes ex stock along with some new modifications and a new revised r4 PCB.

Could the uBITX get any better well certainly it looks like it does!
