More on #hamradio #antenna resonant vs. tuner.

A monoband resonant antenna is dead cheap. Speaker wire from the hardware store, an afternoon to fiddle the right length (you'll need it first time). Absolutely worth it! A tuner is more complicated and expensive than a couple of wires.

A short tuned antenna at a good height reaches DX much better than a full-size too low.

Tuners allow manageable antenna sizes on low bands. I simply cannot fit any 80m full-size.

2/2

@quantensalat @hb9iah

In real-life #hamradio #antenna systems, there are lots of differences between tuner vs. resonant.

As @quantensalat mentioned, bandwidth. Yes. Resonant antennas have limited bandwidth, tuners can be re-adjusted. I have an odd-length dipole I can tune on 10,12,15,17,20,30,40 m.

@hb9iah mentioned losses. Yes. No tuner losses without tuner. Cable losses are least with cable impedance at the antenna end. Place the tuner at the antenna end is good, but difficult. I prefer low-loss cable.

Gone tropo!

Nice tropospheric ducting opening from NZ to eastern Aus. Worked Nick ZL1IU for the 2nd time today with strengthening signals. Also wked Alan ZL1RQ, also on the North Island, just now. 2200km is a very long hop for the 2m band, which normally only reaches to the radio horizon, which is about 80km for me. #hamradio

Relay on Santa Ana Wind Event and PSPS 12/7/23 - 12/10/23 (from our #hamradio emergency group, VC-ACS). #wildfires #emergencies #VenturaCounty #SantaAnaWind #wind #CAwx #PSPS

Ventura County Sheriff’s Emergency Services is monitoring a moderate to strong Santa Ana wind event forecasted to bring gusty Northeast winds to the region beginning today, 12/7/23, through Sunday, 12/10/23.  The increased potential fire danger has led Southern California Edison to monitor numerous electrical circuits in the area for potential Public Safety Power Shutoffs. 

 

FIRE DEPARTMENT READINESS

    The Ventura County Fire Department will go into Plan 1 Brush beginning Friday, 12/8/23 at 2000 - Sunday, 12/10/23.

OPERATIONAL AREA EOC READINESS

    Sheriff's Emergency Services will send notifications to residents potentially impacted by Public Safety Power Shutoffs at 8:00 AM, Friday, December 8, 2023
    The Ventura County EOC is not expected to activate at this time and will remain at Duty Officer status until further notice.
    Ventura County Human Services Agency personnel are available to respond and establish a TEP / evacuation shelter should the need arise.  

SOUTHERN CALIFORNIA EDISON

    As of 12/07/23 at 5:00 PM, 23 circuits in Ventura County are being monitored for potential Public Safety Power Shutoffs. These circuits include portions of the cities of Ventura, Camarillo, Fillmore, Santa Paula, Moorpark, Simi Valley, Thousand Oaks, as well as areas the communities of Santa Rosa Valley, Somis and Santa Susana. The period of concern extends from 12/08/23 at 12:00

I am still not fully convinced I understand how an antenna tuner works.
If I have an antenna with a 3:1 match and a tuner brings that down to 1.0:1 and the radio can then send its full 100W, how much power is effectively radiated? Is it around 75W or 100W?
If it’s 75W, where does the lost power go (heat in the tuner?) and if it’s 100W, what’s worse about this setup than the same antenna slightly adjusted to be resonant by itself (assuming lossless coax and tuner)? 🤔
#HamRadio #NewbieQuestions

Strongly considering rolling my #HamRadio toots back into this account.

I spun up @b4ux1t3@mastodon.radio about a year ago to keep from doing any radio spam to folks who follow me who are only interested in the other stuff I talk about (ttrpg, programming, random parenting stuff, etc.).

But, as a result, I kind of just... Don't ever talk about radio stuff, at all. It's too much friction to hop on another account, even on phanpy where it's two clicks.

I dunno, I guess I'll have to think on it some more.

Through the Amateur Radio on the International Space Station (ARISS) program, students around the world can talk with astronauts onboard the ISS via #HAMradio. As an ISS National Lab education partner, ARISS arranges 60 - 100 of these contacts each year. The program, which is one of the longest-running experiments on the space station, recently celebrated 23 years on station and 40 years in space, as the very first HAM radio contact was made onboard the space shuttle.

Mind your drive level on #FT8 #hamradio. Overdriven sigs cause 'splatter,' an extremely wide signal which interferes with other operators on the band and reduces readability of the overdriven signal. Should be ZERO deflection on the ALC meter. Set the radio RF power to 100% & manage RF power output with the audio level being fed to the radio. If the radio's RF power level is set low, even proper audio input levels will cause splatter as the radio clips to meet the RF power setting.

I have noticed many new hams complain of not being able to get into stations, because of pileups, and it's because they are using spotting networks/QRZ hot list/etc. to find stations (rather than the big knob on their radio). It's ALWAYS easier to find a station calling CQ by spinning the dial rather than waiting until they're trending/popular and hard to contact. #hamradio #tips
