|KL3RR/P QTH BP53gd. East Fork Chulitna river. G5RV jr strung up back in the trees.|
|Icom IC-7300. Laptop for WSJT-X and JS8Call digital modes on 10, 20 & 40m. |
|NanoVNA with included accessories (minus SMA to UHF adapter).|
|Hooked up to the Firestik 2MCKB 2m antenna. |
|Triangle "1" at 143.400 MHz showing 1.05 SWR. Should work well on the 2m band 144-148 MHz.|
This information is crucial for effective antenna building or diagnosing and many antennas can be adjusted to improve SWR around a desired frequency.
|Minor assembly required.|
|Hooked up to power, antenna, and ethernet for interface to PC.|
|Pskreporter stats - HL2 with about 20 receivers over a 24 hour period. Each marker represents a station heard and color denotes the frequency (40m, 30m, 20m, or 17m). Transmissions between Alaska and Europe travel over the north pole.|
|VNC into Raspberry Pi 4 with about 16 receivers (SparkSDR). Sampling bandwidth 96 kHz. 26 Mbit/s going between HL2 and RPi4.|
|Overlooking Anchorage, Alaska 3510 ft ASL. Anytone 878-UV transmitting APRS beacon.|
|On the way up/down some location beacons were not recorded. APRS tracking is limited to where you can be heard by an igate or repeater. On VHF this is basically line of sight to town.|
|2x galvanized conduit (1 & 1.25" EMT) + hose clamps & exhaust clamp saddle + extended ubolt to connect the two sections. Arrow OSJ 146/440 Mhz J-pole now @ ~30 ft HAAT.|
Safety and compliance inspector Jay collecting fee after approval of a Steller installation. Always seal exposed UHF connections with rubber splicing and electrical tape.
2x Comet CTC-50M window feed-thru jumper with vinyl sliding windows. Final setup will go through wall.
|Ground rod installation. Easily bore down 10 ft in 2 minutes using EMT conduit & home water pressure. |
|XASTIR doing RF -> inet gating. Terminal highlights commands to activate Bluetooth serial link after paired to Mobilinkd.|
|KL3RR-2 APRS Igate interface via remote connection (VNC).|
|Electrical hardware mounted on a cutting board. Samlex SEC-1230UL 30-A charger, Optima Blue Top 55-Ah battery. Blue Sea Systems (marine) fuse panel and various other components intended for car audio.|
|Mobilinkd TNC 2.2 w/ Baofeng UV-3R and APRSdroid on a tablet.|
The high resolution screen is ideal for mapping APRS data.
|The radio and TNC are a compact package.|
The Bluetooth is nice as the tablet is not constrained by a physical link to the TNC.
|Anytone AT-D878UV as heard by rtl-sdr+gqrx. Garbled coordinate data in APRS position transmission causes it to be ignored by receiving stations.|
|A second example showing other stations' APRS traffic for comparison|
|Anytone AT-D878UV DMR & Analog VHF/UHF radio|
