G4KLE Operating with Low Power and Portable

Took Elecraft KX3 out last week for a little bit of Low Power (5 Watts QRP) working from Ferry Lagoon (Fen Drayton Lakes, Cambridgeshire).

Ferry LagoonFDLakes3

After making sure batteries were fully charge and packing up my BikeQRP“Shack in a Sack”, I mounted my trusty steed (mountain bike) and rode the 5 miles to a previously recced site for an afternoons Amateur Radio operating. Sun was shining and the temp was about 21C, so perfect for sitting by the lake.

Set up within 10 minutes with my 10m SotaBeam Travel MastSetUpQRP supporting my BandHopper IV Linked Dipole AE on 40m.

On plugging into KX3 I thought there must be a fault as I could not hear anything on the Band, not to be perturbed, I put out a CQ call on CW and straight away I was rewarded with a reply of 579 from…

SOTA – Homebrew 23cm 12 element Yagi Antenna

Get out of the Radio Shack and Live Life

Sunday 18 June 2017. I recently purchased a new 2.5 watt 23 cm transverter from SG-Lab in Sofia Bulgaria. The package includes a 2el HB9VC PCB yagi which has turned out to be a great addition for portable work, particularly from a hilltop with a good uninterrupted view of the horizon. Today from the summit of Mt Taylor VK1/AC-037 locator QF44MP, I worked Rod VK2TWR in Nimmitabel over 130 km, not bad for 2 watts in to a tiny PCB antenna.

While the PCB antenna is a great addition to the SOTA kit, be it for local summits or perhaps on a long hike 10 km or more, what I really need is an antenna with a fair amount of ‘oomph’ that’s non-techo speak for antenna gain, whilst keeping weight and size or length within reasonable limits.

For SOTA purposes, keeping antenna construction as simple as possible is a…

VK1AD WSPRLite beacon past 24 hours to 0945 UTC 26 March 2017

Radio amateur stations in Europe, North America, New Zealand and Australia who report receiving my 20m 100 mW WSPRLite signal.  My antenna is a 40m OCF wire dipole with the feed point at 8 metres above ground level.

VK1AD – 24 hour WSPRLite at 200 mW

Get out of the Radio Shack and Live Life

Results of my WSPRLite operation over the last 24 hours. Having operated the WSPRLite beacon into a 40m OCF for 7 days it’s time for me to turn on my receiver and spend this weekend listening for WSPR signals on 20m (14 MHz), I’m keen to receive a WSPR signal from K5ACL Austin Texas.  I won’t be sitting next to the radio, I have a list of domestic duties to complete!    Next week I will change the WSPRLite operating frequency to 30m (10 MHz) with a lower power setting.

VK1AD WSPRLite on 20m - 24 hour period 20:00 UTC 23/02/17 to 20:00 UTC 24/02/17 VK1AD WSPRLite 200 mW on 20m – 24 hour period 20:00 UTC 23/02/17 to 20:00 UTC 24/02/17

SOTA 6m QRP – VK2 to ZL1 2340 km at 5 watts

Get out of the Radio Shack and Live Life

Thursday 10 January 2017, Andrew VK1MBE and Andrew VK1AD activating SOTA peak Mt Budawang VK2/ST-015.  Surprising success at working ZL1 on 6m 50.120 MHz at 5 watts QRP SSB, that’s right not CW or digital modes, yep voice mode SSB from SOTA summit Mt Budawang VK2/ST-015 for two ZL1 QSOs over 2340 km (1454 miles).   Mt Budawang is 37 km inland from the Tasman Sea.

My 6m gear:  Yaesu FT-817 at 5 watts, antenna is a homebrew 1/2 wave coaxial vertical supported by a 6 meter telescopic pole at 1137 metres above sea level (ASL)

Here is a link to an audio recording (7 minutes) of two QSOs from Mt Budawang, one after the other at 01115 and 0121 UTC.  The first QSO is with Dave ZK1AKW at Tauranga followed by Warren ZL1AIX near Auckland.   🙂


Special thanks to Andrew VK1MBE for holding the squid pole.   Andrew and I…

One SOTA activation and two non-activations — VK3ZPF Ham Radio Blog

Today was a public holiday for the Melbourne Cup. A horse race and we get a day off. I got up early and headed north planning to activate SOTA summits Mt Ritchie VK3/VC-003, Mt Vinegar VK3/VC-005 and Mt Gordon VK3/VN-027. Activating these three summits would boost my points tally by 18 and would be a…
