The standing wave ratio meter, SWR meter, ISWR meter (current "I" SWR), or VSWR meter (voltage SWR) measures the standing wave ratio (SWR) in a transmission line.[a] The meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna). Electronics technicians use it to adjust radio transmitters and their antennas and feedlines to be impedance matched so they work together properly, and evaluate the effectiveness of other impedance matching efforts. V.S.W.R / POWER METER Working of Standing Wave Ratio (SWR) Meters The standing wave ratio meter, SWR meter, ISWR meter (current "I" SWR), or VSWR meter (voltage SWR) measures the standing wave ratio (SWR) in a transmission line.[a] The meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna). Electronics technicians use it to adjust radio transmitters and their antennas and feedlines to be impedance matched so they work together properly, and evaluate the effectiveness of other impedance matching efforts. The actual impedance of any load is the reactance and resistance together. But, the SWR meter cannot measure both, instead measures the mismatch. To measure the impedance, more complex radio frequency measuring devices must be used. For the SWR meter readings to be accurate, the device must be matched on to the line impedance. Any transmission line will have a certain loss. When this loss occours, the reflected signal will be attenuated when it travels back along the line. Thus, for the SWR meter to be efficient, it must be connected very near to the antenna and further away from the load. The value of SWR will be more when it is nearer to the load. When using a passive type SWR meter it is always better to remove the device from the line. As these devices have diodes and other harmonics producing components, intermodulation may occour.

Most cell phones and tablets do not support any kind of external Push-to-Talk (PTT) function on their accessory plugs,so users have either had to use the device screen or Bluetooth to make the PTT work. Sometimes it's not easy to push a PTT on the device screen, and Bluetooth can be inconvenient since it needs pairing, battery charging, etc. The SE-01 PTT solves this problem by having the computer software inside! (like phone calling, music playing, photo taking, etc.) Manual Wholesale Quotation Shopping Package Include: 1x SE-01 PTT Controller with Mic 1x 3.5mm MONO Earpiece Set-up wired accessories for Zello Android Depending on the Android device, you may need to disable Google Play Music under applications to prevent the headset hook from bringing up music. If you're using one of the Zello recommended accessories that function as a push-to-talk device, log into your management console and go to Settings > Android > "Enable Use specialized wired PTT speaker-mic or headset" and save. 1. Connect the accessory to your mobile device 2. Open Zello "Options" > "Push-to-talk button" 3. Select "Add Button" on the top right. You'll get a prompt asking you to press the desired button and it will be added as a "Headset hook". 4. Make sure the button is set to "Toggle mode" and that "Handle headset button when in the background" is enabled. Even though it's set to toggle mode, the accessory will work as a push-to-talk mode if it's listed as push-to-talk from the website. If you're using a device not listed, it will most likely only work as Toggle mode. iPhone/iPod/iPad Although Zello does have the option to map a headset hook from an Apple headset, it is not often reliable. Zello does not have the control to maintain the headset hook for PTT control, so the headset button will may sometimes trigger music. To prevent this from happening, make sure you don't have a music app in the background while using Zello. Connect your headset to your iPhone and then follow these steps: 1. Set push to talk button "Action" to "Toggle". (Zello menu>Options>Push To Talk button>Action>Toggle). 2. Make sure you have enabled "Headset/remote control" enabled. 3.

All forms of SWR meters measure SWR, standing wave ratio on a transmitter feeder. Using SWR meter is relatively easy, but one should be able to interpret the results when using it. In general, VSWR and SWR are the same. When using VSWR meters to measure the the performance of a new antenna, always one should prefer to use up to 3W power and a clear channel. The following procedure can be used to use the meter. Push red button at two times to mode "V.S.W.R. meter " ,LCD display show Connect the SMA (mark TX) to Radio output . Connect the SMA (mark Ant) to ANTENNA When the the LCD show 1.00 to 1.50 , 1.0~ 1.5:1 mean the antenna is suit the frequency. When the the LCD show 1.50 to 3.00 , 1.5~ 3.0:1 mean the antenna is not good suit the frequency. When the the LCD show 5.00 to 19.99 ,5.0~19.99:1 mean the antenna is not suit the frequency. The VSWR meter is connected in the feeder from the transmitter to antenna. For the feeder convenience, SWR meter is located at the transmitter end of the feeder. This helps to monitor the actual VSWR values. One should know, where exactly SWR can be measured. There is always some degree of feeder loss, which has a major effect on the VSWR readings. Feeder loss absorbs power in both directions. When the reflected signal is reduced, there is a high level of feeder loss. The reflected signal gets reduced as a forward signal to the antenna, later it’s reflected back to the transmitter. Since the signal is reduced on its way to the transmitter, an antenna with poor match and high VSWR will be fine at the transmitter. Hence, when a feeder that induces a high loss is used, VSWR is good at the transmitter, but at the antenna, it may be poor.

By definition, VSWR is given as ratio of maximum voltage on the line to the minimum voltage. The same can be expressed in terms of forward and reflected wave voltages.

Q1) Can I also use SW-33plus on base radio like icom ic2300h? A1) It can use on sw33,but not include adator. Q2) SW-33 plus check the antenna and swr is 19. I rechecked other antennas and it's provided dummy load, 19. A2) Please make sure that the radio that you are checking is analog ? check sw33 use dummy load is 1.0 ,mean the meter is normal Q3) SW-33 plus good to measure mobile Radio? A3) For mobile Radio, we suggest using SW102 Q4) is it possible to test vehicular radios (power less than 100W) or just portable radios? In case yes, do you need a dedicated Load compatible to that power, correct? A4) Can test vehicle radio , but need to replace the adapter, high power dummy load Q5) Easy to use, results indeterminate The device was very easy to use. The results were anything but usual. I used a buddies swr meter and it was more accurate than this one i purchased. For my setup my buddies meter read swr of 1.75, this meter read of 3. It fluctuated up to a swr of 12. A5) Each radio will have some tuning errors. An SWR reading error of 1.25, plus or minus 1.5, is normal. If tested with a 50ohm dummy load, the reading is 1.0:1 - 1.05:1. Q6) I've read, "doesn't work with DMR radios" & that it "doesn't work in DMR mode". Simple question, Does it work with a DMR radio in set to FM mode? A6) SW-33 MarkII not support DMR radio Q7) HT VHF analog power out with dummy load and with antenna appears to match radio vendor specifications, although I do not have an in-line commercial watt meter to validate. However, on UHF analog (435.000MHz) the device displays an all white (pixelated) screen. See photo. This is consistent across multiple radios, power (3, 5, 10 watts) with native antenna or with the dummy load. Results in an inability to measure UHF power, vswr, and requires the device to be powered off and back on to recover. A7) remove the back cover, unplug the battery, and then plug it back in. Resetting the battery will resolve the blank screen issue.

A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillation, or pulses per second in a periodic electronic signal. Such an instrument is sometimes referred to as a cymometer.

Q1) Hi SW-28HF is most inaccurate. I put 80 watts peak in and it displays >169. I put 2.8 watts in as a carrier and it reads 5.7 watts. Swr reads wrong too. On a resistive dummy load of 50.9 ohms it reads 1.2 swr. The display sometimes has artifacts until it is powered off and back on. A1) Please try to set the SW-28 as followings SW28HF rest data to FW 100 ,RW 100, Then Hold the menu, fast push peak botton 2 times to entre the menu mode set the select menu to [FW set 86 ], select menu to [RW set 96], long push menu change to" + "or " - " and then SAVE Q2) does SW-HF28 work with this Frequency is 27.385 MHz in SSB mode A2) It work 27MHz ,AM/FM mode , but not for SSB Q3) The ref (reflected power) didn’t have a decimal? The fwd displays a decimal? I’m talking about the digits under the swr, there’s no decimal So would 1000 equal one watt or ten watts. 0025 equal 1/4 watt? A3) It has a decimal point, which is at the front, because the reverse power value is measured more finely, so it is placed at the front. Q4) Can I check the output power without a dummy load? A4) It need to use a dummy load. Accurate power measurement requires a load. Connecting an antenna also allows power measurement, but requires counting. This is because the SWR must be 1.00 before the value is reached for accurate power measurement. Q5) What is the battery of SW28? A4) 502540 3.7V 550mah li-ion battery
