  • Check your SWR on channel 1 and 40. It should be around 1.5 across the band. If it is over three, you need to adjust the length a little bit at a time. If it is higher on 40 you need to shorten the tip about a quarter to half inch at a time. If it is high on 1 you need to solder a little on the end to make it longer.

    Dec 29, 2017 · With the microphone keyed in, flip the SWR meter’s switch to the “REF” or the “SWR” position. Record the readings on the SWR meter quickly then release the transmit key on the microphone. Repeat this process for channel 40 using the steps 4-9 above Select Rule; 16 TAC § 3.2(a) [SWR 2(a)] 16 TAC § 3.2(b) [SWR 2(b)] 16 TAC § 3.3(1) [SWR 3(1)] 16 TAC § 3.3(2) [SWR 3(2)] 16 TAC § 3.3(3) [SWR 3(3)] 40 Meters: 7.133 MHz. 30 Meters: 10.122 MHz; 20 Meters: 14.000 MHz. 15 Meters: 21.085 MHz. 10 Meters: 28.400 MHz. This would give me between 2.00, to 1.7 to 1 SWR at the bottom of each band. The upper end was left to fall wherever it ended up, in most cases the top end fell past the high end of each ham band.

    If the reading is a little high, say just over 2 then check the SWR readings on channels 1 and 40, if the reading is higher on channel 40 then the aerial is too long and needs to be shortened slightly. If the reading is higher on channel 1 the aerial is too short and needs to be extended.

    If we want a circuit that would fit in a small enclosure, and give an indication of minimum SWR, this circuit does the trick. The trick is based on the ever popular WM-1 made by Oak Hills research, with a few change. Now the SWR on 40 and 20 was shot. 2.5:1 or 3:1 at best. 15 got worse (2:1) and 10m was just fine. Yes, the drain holes do face downward. All of them. - Then it got freezing cold. The SWR got a bit better on 40 and 20 (not great) and 15 looked just as it should. 10m no problem. Now when I transmit on 20 and 40, the SWR moves up rather quickly. The high Q of the magnetic loop means that the 1:1 SWR null is only a few kHz wide, and retuning is necessary whenever you QSY in frequency. Tuning the MFJ magnetic loop is not difficult, even with the manual tuner. Technically, it measures the standing wave ratio (SWR) in your communications transmission line of channels, check the SWR readings for channels 1 and 40, because the values will change. Can high SWR damage a radio? It's theoretically possible for your setup to reflect enough heat to your final RF...

[GapAntennas] To: GapAntennas Sent: Sat, Sep 14, 2019 11:07 am Subject: [GapAntennas] High SWR ON 40 Just got the Titan installed. SWR looks okay on most bands, excellent on others. SWR is perfect for both bands and for 18 MHz condenser C will do the trick. Pretty high trees are perfect for support points. 2 el phased vertical for 40 meters. Combining 2 verticals with 2 elevated radials each and 3 pieces of coaxcables gives you a phased vertical.An SWR of 1:1 means that the peaks and valleys of the wave are equal, which is desired. However, a high SWR means that the peaks and valleys (nodes) have a high ratio. If you could go along the feed line and measure the voltage (or current) at different places on the line, you would find that the voltage varied to the ratio of the SWR.
