Is There Anybody Out There?
Dave ZL1DL arrived at the clubrooms today to find a fire appliance parked up by the driveway chain. On hearing voices from the region of the access path to the rocks, he decided to investigate. Before getting too far down the path, he was met by a firefighter coming back… [Read More]
Quite a large turnout today – 12 persons all up. Following the 5775 repeater lockup earlier in the week, we migrated the power supply to battery, to hopefully eliminate the power glitch that caused the latchup. Simon and Harry looked further into the TX/RX filter arrangement for the repeater and… [Read More]
Attending: ZL1DL, ZL1MRT, ZL1TOF, ZL3CK. After Martyn ran the 80m AM net, it was decided to try the T-98 40m AM TX, in which Graham had installed the improved sequencer. After correcting wiring for the oscillator control, we discovered there was no grid current (i.e. drive) to the final RF… [Read More]

No significant difference noted so the filter was removed. It was then play in the park time. Four antennas were set up: ZL4ROB,… [Read More]
We had seven turn up at times between 09:30 and 17:00. Graham completed the sequencer install for control of the 40m T98 transmitter. Martyn ran the AM net while Harry and Luke worked on balun construction. Luke brought muffins for morning tea :-). On air measurements made by Harry and… [Read More]
Prior to todays meeting, we trialed the new rigging for the portable antenna pole. A much improved arrangement saw the pole set up in a few minutes. Martin made a quick contact on 40 using his K2, but all too soon we had to retire to the clubrooms for the… [Read More]
On 10/01/24, Dave L fitted a high pass filter to the IC-706 remote, HF antenna line. The IC-706 has historically suffered from serious crossmod – believed to be substantially caused by an AM broadcast station. The filter significantly attenuated frequencies below 80m, resulting in (what appears to be) substantially clearer… [Read More]

Another one of MPRGs famous in East Auckland brainstorming sessions under way during this Sunday’s gathering. Several biscuits were harmed at this time.
