Alexa, Why do Hams dislike FT8?
Hams may have various reasons for disliking FT8, a digital mode of communication in amateur radio. Here are some common concerns and criticisms:
Lack of Personal Interaction
- Minimal Communication: FT8 involves short, automated exchanges of information with little to no conversational content, which some hams find impersonal.
- Reduced Social Aspect: Traditional modes like SSB, CW, and phone allow for more personal interaction and socializing, which many operators value.
Skill and Challenge
- Lower Skill Requirement: FT8 is relatively easy to use and doesnβt require the same level of operating skill or knowledge of radio theory as modes like CW or SSB.
- Less Technical Challenge: Some hams enjoy the challenge of optimizing their stations and skills, and FT8βs automated nature can feel less rewarding.
Impact on Bands
- Band Congestion: FT8βs popularity can lead to crowded frequencies, making it harder for operators using other modes to find clear spots on the bands.
- Dominance of Bands: The widespread use of FT8 can sometimes overshadow other modes, leading to a perceived imbalance in band usage.
Perceived Value
- Questionable Accomplishment: Making contacts with FT8 can feel less like an achievement since it relies heavily on automated software and less on operator skill.
- Awards and Certificates: Some operators feel that awards earned through FT8 contacts are less meaningful compared to those earned through more traditional modes.
NOTE I RESPECT FT8 AND ENJOY OPERATING IN ROBOT MODE SO I CAN MAKE LOTS OF CONTACTS WHILE SNORING AWAY IN MY SLEEP

You made 8 contacts Steve on FT8 and I made 32 on SSB during the hour. I got my activation done so catch ya later!
Why do you always do POTA?
Hams enjoy operating in Parks on the Air (POTA) events for several reasons:
Connection with Nature
- Scenic Locations: Operating from beautiful, natural settings adds an element of enjoyment and relaxation.
- Outdoor Activity: Combines the hobby of amateur radio with the benefits of being outdoors, promoting physical well-being.
Challenge and Adventure
- Portable Operation: Setting up and operating a station in a remote or temporary location presents a fun and rewarding challenge.
- Adaptability: Hams must adapt to different environments and overcome obstacles, such as power sources, antenna setups, and varying weather conditions.
Community and Camaraderie
- Social Interaction: POTA events often bring together like-minded individuals, fostering a sense of community and camaraderie.
- Engagement: Operators enjoy the interaction with other hams worldwide, exchanging QSL cards and earning recognition.
Skill Development
- Technical Skills: Provides an opportunity to test and improve technical skills, from setting up portable antennas to optimizing power sources.
- Operating Skills: Enhances operating skills under different conditions, improving proficiency in making contacts (QSOs).
Recognition and Awards
- Achievements: Many hams enjoy the recognition and awards associated with POTA, such as certificates and endorsements for activating or contacting multiple parks.
- Friendly Competition: Participating in POTA events can add an element of friendly competition, motivating operators to improve their performance and achieve more.
Promotion of Amateur Radio
- Public Awareness: Operating in public spaces helps raise awareness about amateur radio, potentially attracting new enthusiasts to the hobby.
- Community Service: Demonstrates the capabilities of amateur radio in providing communication in remote or emergency situations.
Personal Fulfillment
- Sense of Accomplishment: Successfully activating a park and making contacts provides a sense of accomplishment and satisfaction.
- Relaxation and Enjoyment: Combining a beloved hobby with the tranquility of nature creates a unique and enjoyable experience.
These diverse factors contribute to the appeal of Parks on the Air events, making them a popular activity among amateur radio operators.

Why 20 Watts John Why?
I often get asked, βWhy use 20 watts when my radio can do 100?β
Hereβs why:
First, itβs about battery and power management. As a QRP enthusiast, operating at 20 watts simplifies my life, especially for SSB (Single Sideband) communication. While CW works great at 5 watts or lower, when readability is crucial, my park activations are at 20 watts. Yes, I operate at 5 or 10 watts SSB when the band permits or when Iβm feeling adventurous.
The maximum power output of 20 watts is the sweet spot for effective SSB communications. The difference between a 20-watt and a 100-watt transmission is about 1 to 2 S-units on the receiving end, according to the Collins Radio standard of 6 dB per S-unit.
Most military and Australian bush HF manpacks are rated at 20 watts maximum output power. This level balances communication effectiveness with the practicality of how many batteries you need. Adding compression also provides a 6 dB boost in the modulation envelope, effectively enhancing your output power.
At 20 watts, I use 9 amps instead of 15, which translates to almost double the battery life. I can use a smaller and lighter 9aH battery instead of my heavier 18 or 30 aH battery pack.
I found two 6aH LifePO4 batteries at a liquidation store for $5 each. Wow!
I can pull 10aH out of the battery with no problem on SSB, giving me about an hour of run time, which is fine for a park activation.

The JNC Radio Chelegance MC-750 on the POTA rocks
After several thousand contacts with the MC-750 I can say that it is still like new. Of course, after a snowfall or rainfall I do wipe the antenna before storage into its excellent case.
I love this antenna because it works with my QRP radios and Ft-891 that do not have a tuner.
Jab spike into grass, extend whip to 14Mhz markβ¦go operate as SWR is always under 2:1 using its fixed radial length of 10 ft.
4 radials (wait isnβt it counterpoise?) has been proven to be a great performer. I always lay them on the ground and it just works with QRP contacts into Europe on 20m.
I have put all my end feds into a bag as to really work DX you need an efficient antenna without Balun losses and tuners in place (more losses) AND a low angle of radiation. The MC-750 gives you this.
I also tried the antenna on 40m understanding its a bit short so the performance is a bit short (usually an S unit or 2) but the speed of activation and recovery is awesome.
I deployed it this time on the rocks and was rewarded with some good contacts on 40m. The 40m coil is well built and has protection from the elements. I love POTA and my POTA is usually on 40 or 20m.
The Q is very good for the coil and the bandwidth is good so readjustment isnβt really needed when hunting for parks.
JNC is working hard to bring more affordable antenna products to the market place but only are they released after much testing and protyping.
I love the custom case with pockets that contain everything from getting lost. Its stood countless tossing into the truck, rain pour and transport on my bike. This alone is worth $60. The zippers work properly and there is room in the case for coax and even a QRP labs QCX radio. Even a swiss army knife and a energy bar and water flask.
My French River activation and Field day activity included 2 primary antennas (I brought a third for testing) and after the poor results with the end fed long wire with my 9:1 balloon I just kept the MC-750 connected. The band change from 40m to 20m was fast as well. Recover the 40m coil then extend the whip to 14mHz and run back to the cabin to operate.
The team has added some accessories and other items of interest to hams at price points that are affordable and designed and built extremely well. Pride in workmanship is a key company value.
I have had two MFJ telescopic whips fall apart due to poor quality and workmanship but my MC-750 whip although lighter in weight has worked admirably.
Get OUT and operate not sitting on a couch watching YouTube on people activating parks. Operate not watch!

Icom 705 at 5 watts with the MAT-705 tuner for the end fed and the Heil headset. QRP works and life is long enough.

My DIY 9:1 hangs off a nail

Working DX on 20m Thanks to the F6 in France using 5 watts SSB.
![](../themes/icons/grey.gif)
just some simple macro work cant work DX all day right?
![](../themes/icons/grey.gif)
Just stick the ground spike into the crack and go operate. At 17 ft and the base coil its a formidable weapon for 40m activity especially where a dipole cant be put up. I am constantly surprised how well it works on 40m with High Q and great bandwidth.
Hear em , work em, log em No problems
