M1KTA SO2R pt 2

Following on from as asked I will post some more details of the Arduino shield shortly.

Might not be until after C6/BERU trip mid March though as not as much time left before going.

As remarked yes only doing only simple cw and audio switching. NO SSB or PTT. You'll have to make sure you sort out PTT out so when one rig is keyed it sends a PTT lock out to the other so doesn't TX.

On C6 trip will be reviewing some kit

Been asked to review a bit of kit (rig accessory) and so will provide a link/updates on the blog once spoken to the vendor after trip.

Interesting option, so if any other vendors are ever interested in asking....

Had these in the workshop for a while and thought was time to make then up.

Basically Butterworth band-pass filters for 80m, 40m, 30 and 17m.

Used T80-6 torroids and 500V (I think) SM caps.

Should be good to 20W at least, probably a lot more.

The 80m and 40m ones I used thin wire in the winding so probably not good for higher powers, the 30m and 17m ones used 16SWG wire should should be good for 100W

C6AKT now on clublog & LoTW

As I found out C6AKT was a reissued reciprocal SK call (Glenn W2CXX) and they had registered it through clublog and LoTW etc. So had to go through the steps needed and they are both now live again so requests for QSL will come to me.

Please make sure you realise I will not be dealing with requests for QSO or operation before my time there 8th March 2018.

"On 2018-01-13 16:31:45, Dominic Baines (M1KTA) requested that C6AKT be transferred to their account.

The allowed 28-day waiting period has now expired, and glen fadden (W2CXX) has not responded.
As a result, this Callsign Transfer Request has been automatically completed and C6AKT has been
transferred to Dominic Baines (M1KTA) as requested. The original log has been renamed C6AKT-1 and
remains under the account of glen fadden (W2CXX).

This resolution is now final, and the Callsign Transfer Request has been closed.

Keyers work in SO2R mode

Just tested, before going to the salt mines (sadly work still), that can use the keyers (K1EL Lite and WKUSB or K3NG) and the ATS-3B and K2 rigs independently of each other when switching manually and they are fine. In case ask/puzzled, the plan is I will using ONE manual key input through the SO2R and those will go into the 2 keyer paddle inputs. But I'll use win-test to key just ONE of the rigs the other will be manual.

Will be testing the win-test functionality and effect when change from rig1 to rig2 etc over the w/e.

Got to make sure the TX lock out works.

A 5th 10m travel pole goes in the bag...

And still inside weight limit :-)

The suggestions are:

4SQ try 4SQ+1 so a 5th parasitic element might help in one direction or other.

The theory is to either place it in the dead centre or inline (along the diagonal) with the required direction.

IF there is 15m or 10m activity, add a second GP.

C6AKT 100% homebrew

As asked... Will be QRP.

The C6 trip will be 100% using home brew kit.

2el on 80m, Supports are two 12m poles from Spiderbeam, with top capacity hats. Directed end-fire towards UK/EU. Wires all new.
4-square on 40m, Four 10m traveling poles from SOTABeams will support the radiators, radials all new wires from CPC. Using a TK5EP based hybrid controller, same as used elsewhere, this time M1GEO made me up a QRP PCB and much lighter so will be trying that instead of the S2JW version.
VDA on 20m, 12m pole, Tesco chopping board and parts from two 4m poles. See details how to build one. TX6G David Aslin G3WGN also has excellent designs. There is a 1/2 wavelength version out there too...
GP's 15m and 10m (Not expecting much if anything on 15m and 10m)

Feed is NEW Aircell-5 with 75ohm webpro 100 between the phased antennas.

Taking coax stubs for 40m and 20m made from coax I picked up from SM7UCZ a while back (tnx G4BWP for the conversations and corrections)
W3NGN based BPF (but qrp versions) between the TRX and antenna

I'll use an SO2R arduino controller not really for running SO2R but to switch between the antennas.

Rigs will be ATS-3B and K2
Homebrew Softrock "Lite + USB Xtall" V9.0 Si570

I do have KX3 which I 'built' but they don't really fall into the hombrew category so they stay in UK
