BERU 2015


Well it seems I am in the BERU Team Africa...  so please help me help you add a rare one.

Some comments from me for those that might try a contact.... please SLOW DOWN ALL EXCHANGES. If you are only in it for the qsl (BERU countries only please I will likely ignore you otherwise) Yes I know it is a contest and needs to have rapid exchanges but if you want the C5 then please slow down or I might not get the whole exchange correct. The reason is very simple....I may just delete the qso. In 2014 I got fed up being sent a serial number and tu at 30wpm (probably from some macro) and never getting it and I'll not put in 001 entry as I will get penalised, you will get a NIL and will loose points.

I will almost certainly confirm BOTH your serial and mine and I'll not give you my serial number until I have yours.

Please please make sure you think I have BOTH numbers correctly. Very happy to be told I got it wrong and corrected.

The example exchanges I will be used are:

If I am search and pounce... (I'll probably contact the 'big guns' myself and I'll have listened loads so I will probably know what serial number to expect)

abc: cq G3ABC test
kta: M1KTA
abc: M1KTA 5nn  nr
kta: sri   nr agn                       
abc: M1KTA 5nn  nr           or just 5nn cfm nr on the repeat
kta: r 199 nr
abc: tu G3ABC

or

If brave enough to send a CQ:

kta: CQ M1KTA BERU test
abc: G3ABC
kta: G3ABC 199 nr
abc: 599 nr                           
kta: nr ?
abc: 599 nr                             
....  repeat until OK
kta: tu  M1KTA BERU
 
Oh yes I'll be the slow one in contest (expect sub 16wpm).

Africa DX contest is on too so I expect might get interesting as I expect I will be cq'ing and will get hassled by the odd one.

Note I KNOW these stations should be in BERU from Africa but dare I suggest listen on air:

5V/G3TXF, 5Z4LS, ZS1EL, ZS1C and 7Q7BP

Be aware many AF stations might not be in BERU and will be operating in SARL contest.

NOTE if I am in BERU almost definitely NOT on AF-060

K2 Build

Been working on this for ages (almost a year now).

It is a K2, fully loaded, with 100WPA and ATU in an external encloure.

The Mic the end user will use is different to mine so used the K2 mic rework eliminator... here this is it being fitted. To change mic you adjust the jumpers.


Control board removed this is the rear of the front panel. P1 mike header jumpers already in place. But not configured yet.


rework eliminator in place (I have set the jumpers for the heil traveller headset I have)
 Control board back in place...
 Then the AF filters, dsp and RTC
 Side panel off to show the jumpers.





Testing battery for C5

Got the same type of motorbike battery will have in C5... testing operation...


They sell them dry and you add electrolyte (sulphric acid)... They will then have 9.5AH charge and will run what I need for more than couple hours.
Will recharge constantly at 0.9A from Pro-peak smart recharger, using a PSU.

 
So in the photo.. At the back left, a PSU... actually the workbench one but doesn't matter.... output is 12V... into the Yellow (front left) smart charger (will do Pb, Li, NiMH, NiCd batteries and in all sorts of combinations, mine is the one that has small charge/discharge rates, no fan so silent), from there to the battery... I have meter in series (just to see the charge rate) and a small ebay voltage LED module across the battery. It takes about 12 hours from flat to recharge it.... I should only need it in C5 twice (not this actual battery but another like it.

I can also just shove 13.8V into the battery at 2-3 amps (got a couple limit resistors and 6 amps diodes in a set of leads already (wirewound 10W things) but that will wreak the battery, long term but will recharge in only a few hours, which I might do for the trip last day if I do not need it after. I'll give back to the place I bought it after.
 
If operating from the hotel mains (might be possible) then will use PSU and the recharger at same time ... It is RF quiet I know this already.

C5 in 2015

Once the current build backlog is dealt with (K2 to finish off) I will be off to The Gambia in 12th March for BERU. Will probably activate AF-060 Bijol Island one morning or afternoon when out there (until 17th).

QTH will be the beach again near Brufu. Probably same place as I did last year....
