This is video number one-hundred in this series.
In this video I use Intercept Point Optimization to pull out a very weak signal while improving the S/N ratio of a stronger signal. Intercept Point Optimization enables a very low level of amplification in the first mixer stage of the receiver. The amount of amplification is optimized for signal-to-noise ratio. It’s just enough amplification to overcome insertion loss through the roofing filter, but not enough amplification to degrade the signal-to-noise ratio.
Note that the S-meter is calibrated at 14.2MHz, with AMP1 enabled. When IPO is enabled , the S-meter readings will be low. S-meter readings are relative though. If someone is judging their station by the S-meter reading I give them, I like to qualify the reading by telling them the type of antenna I’m using, and my transceiver model. If I have them at S9+10dB with a dipole, that’s one thing. If I have them at S9+10dB with a 4-element Yagi beam aimed at them, I’m doing some heavy lifting. So it’s all relative. I listen for the amount of background noise between words. I can do the same with SSB and CW. I generally consider full-quieting (no background noise between words) as S9. My QRP CW rig doesn’t even have an S-meter, so have to give signal reports completely by ear. My “by-ear” scale is as follows:
S1 = Barely readable
S3 = Readable but noisy
S5 = Easily readable but still noisy
S7 = Perfectly readable with only a slight hiss
S9 = Perfectly readable with no noise (aka full quieting)
For more information about S-meters, I recommend this video: • Decibels, S-Meters, Am...
I cover the many capabilities of the FTdx10 in the “Additional FTdx10 Videos” list on the Collections page of my Patreon site. There are nearly 100 tutorial videos, as of the release of this video. You can view the full series by becoming a supporter of my channel at: www.Patreon.com/N4HNH
Note that most of the operating techniques I show and teach on my channel can be applied to other transceivers, even other brands of transceivers. Some knobs or buttons might be labeled differently but he function is the same. I have no allegiance to Yaesu. No manufacturer makes a perfect radio. They all have strengths and they all have weaknesses. I like to point those out. Yaesu thinks that I am targeting them, but I am not. In fact, they generally have the fewest weaknesses. It’s just that I want my viewers to know the good, the bad, and the ugly, so they can make informed purchase decisions. I am able to be objective because I have no allegiance to a particular manufacturer. My work is supported by private donations, via www.PATREON.com/N4HNH.
At the end of this video, you will be able to see a listing of some of the supporters of this channel who made this video possible. These are people who have supported the channel via Patreon membership, as what I call long-haulers. Long-haulers have supported the channel on a long-term basis. There are 4 levels of Patreon membership, including S5 (Associate), S7 (Executive), S9 (VIP), and S9+ (VIP+). S9+ (VIP+) denotes an S9 (VIP) member who voluntarily chooses to give over and above the amount for S9 (VIP) membership. They help me continue to produce videos even though most people do not contribute toward the cost of my mission. Without their support, I cannot bring my viewers uncensored content.
I hope you enjoy this video and find it helpful. If you find my channel informative and entertaining, I hope you will consider joining my support group by clicking on: www.patreon.com/N4HNH There are 3 levels of support, including exclusive content. Visibility of premium content is determined by the level of membership you choose. The higher the membership level, the more content you have access to. VIP members are invited to participate in periodic Zoom meetings.
Most videos are visible to the Patreon team members long before they are released for public viewing. Some videos are never released for public viewing. Annual S7 (Executive) and S9 (VIP) members have access to the menu optimizations PDFs I’ve written for the FT-891, FT-991A, FTdx5000MP, FTdx101D/MP, FTdx10, and FT-710 AESS. Annual S7 (Executive) members can receive one menu optimizations PDF while abbual S9 (VIP) members can receive multiple menu optimizations documents, plus my FT8 configuration guide for either the FTdx10 or the FT-710 AESS. Future radios might be added. The documents are copyrighted. They shall not be divulged to anyone else without written permission from Doug McAlexander, callsign N4HNH.
N4HNH Radio has a Web site where you can purchase T-shirts with some of the sayings you might hear in the videos. Some of the more prominent videos are featured there as well as a page geared toward ham radio training. Go to: www.n4hnhradio...
