visit to Mt. Sugarloaf lookout grid QF57sc, west of Newcastle - 21st May 2023

 As part of a recent road trip, I did a visit to Mt. Sugarloaf lookout SF57sc, west of Newcastle, home of VK2RNC, to look for a spot for doing 23cm DXing, plus activate VK2RAG and VK2RTZ 23cm repeaters, neither of which I could keyup. I also wanted to know was this site useful for doing WIA VHF/UHF Field Day contests from. Basically, the public carpark at the top, only gives a small window to operate up towards Port Stephens and up the NSW coastline,  any other direction would be useless due to heavy forested trees.

I did a walk up to the lookout, this was a rocky outcrop at the top, quite suitable for VHF and above, operating portable DX, but be aware that lots of tourists walk up to the top lookout, so you can't just consume all the space up there with gear and antennas, but I guess approx 50 sq metres of flat rock at the top surrounded by metal railings, good to strap small temporary antennas to. There is a road to get to the commercial radio site (not NBN3 or ABN sites) leaving about a 50 step ascent to the top lookout,

Grid Square locator is QF57sc and height approx 436m ASL

Re-purposing Dyson 56v (50v) lithium pack as a 12v 20A/hr pack

 Recently,  Dave VK2JDS directed me to build a 12v 20/A/hr lithium pack for amateur radio use for portable use when lugging microwave equipment up to a mountain top for DX. We used a discarded Dyson vacuum cleaner 56v lithium pack,  because Dyson use high quality 18650 cells, so it is only the BMS boards that fails, therefore you can repurpose and reconfigure the lithium cells as a  high current 12v pack with a bit of careful plastic cutting, and a bit of snip and solder of battery tags in the right places, plus adding a new cheap BMS controller board from Ebay, plus remove and discard the temperature sensing boards as shown.

The pics show the original pack, plus the cell pack removed and a chopped up cell pack which can be resoldered  in parallel to provide 12v at 20A/hr, once separated you left with four single cells for other projects, and 4 x 12v cell blocks to solder in parallel,  keep all ground points soldered, then all 3.7v points soldered in parallel, then all 7v points all soldered together, then all 12v points soldered together, then when ready you solder the 0v, 4v, 7v and 12v points of the new BMS board to the cells, trying to do this earlier in the soldering phase can damage the new BMS board. Check at each step that you still measuring the expected voltage at each parallel point, ie. 3.7v,, 7v and 12v, otherwise you could end up with sparks and smoke. 

BECAREFUL not to short out any opposing contacts, as you will get big sparks and smoke. When finished, add a circuit breaker or inline fuse, then tape it up and place in a suitable sized plastic jiffy box as your portable 12v 20V/hr rechargeable battery supply.

Road Trip 19th to 21st May 2023

 road trip to Wangi Wangi and surrounds of Lake Macquarie. I took 23cm all-mode, but no luck working VK2RAG  or VK2RTZ 23cm rptrs. 
 I did go up to top of Mt. Sugarloaf to check out possibility of doing some portable microwave activity from here in the future.  I gave some CQ calls on 1296.100 and 1296.150 from Sugarloaf carpark aiming up the coast.

Mt.Sugarloaf, QF57sc,  436m ASL at the lookout, need to carry gear up about 100m from caarpark to the lookout, to be above trees.

Road Trip 12th - 14th May 2023

 Sydney - Orange - Gowan - Sydney

return trip late Sunday night, with low temperatures 6 to 10deg C yielded fuel consumption of 9L/100km from my Jackaroo. Only used a tank of 95 octane, usually it consumes 3/4 of a tank in warm weather.

3.5Hrs via Katoomba  return trip, compared to 4hrs via Bells Line Rd for previous similiar late night returns

APRS VK2KFJ-9 is RF  145.175 MHz  and VK2KFJ is TCPIP



Whilst at Gowan QF46pu, did some RF testing, accessing VK2RYL 147.225 MHz requiring 91.5Hz ctcss, VK2RCD 146.725 at Dubbo, VK2RYG 146.875 MHz requiring 91.5Hz ctcss at Young, VK2RKG 146.900 MHz Bathurst, VK2RCW 146.900 MHz at Gowan, VK2RCC 146.800 MHz at Coonabarabran, VK1RGI 146.950 MHz Mt. Ginini, plus contacts on 146.500 FM simplex.  I could hear WIA broadcast  via VK2RAG 146.725 MHz, VK2RMP 146.850 MHz Maddens Plains, VK2RWI 147.000 at Dural.

Also heard on Sunday morning at 7.30am, two U.S. stations talking on their local 29.680 MHz 10m repeater for 30mins.  Later that day could hear the WIA broadcast on a 29.680 repeater.either in vk7 or vk6, plus activity on 29.600 MHz including Murray ZL3MH,  plus Indonesians on 29.120 MHz

Road Trip 5th to 7th May 2023

 Did a road trip, Sydney to Mudgee, via Singleton, Muswellbrook, then Mudgee to Young via Gulgong, Wellington, Molong, Canowindra, Cowra, then Young to Sydney via Monteagle, Boorowa, Rugby, Crookwell and Goulburn.

Heard Murray ZL3MH each day whilst mobile on 29.600MHz FM,  I still getting RFI being generated by the car. I just not happy with noise levels on HF, 6m and 2m. 

Some repeaters that I took notice of their coverage, 438.025MHz  from VK2RCN Newcastle, could hear it do regular idents from Sugarloaf up to Singleton. Could also work  VK2RZL 146.875MHz  from north of Singleton up to Muswellbrook and out to Merriwa, it requires 91.5Hz ctcss. 

Then on road to Young could hear activity from the Wagga guys on VK2RYG 146.875 MHz whilst I mobile from about Cudal through to Young, that repeater is part of the Wagga ARC network, situated near Young.

Here is my APRS track for the trip.
