Connect the SMA to DUMMY Load Caution : Please use correct dummy load , High power will damage the dummy load. 1.2 How to measure SWR? 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) 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

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.

Q1) Why SF401 frequency counter always show frequency less than it's actual? ( For example: installs on 433.000Mhz radio, counter shows 432.999Mhz) A1) Please go to [System] and set [Freq Offset] to adjust the deviation Q2) It can check UHF, but cannot check HF A2) Please try the followings * put the ATT button into left hand side * Make sure that the antenna is HF, as the antenna that we provide us dual band (VHF/UHF) only * please try to slant your radio to the frequency counter to make sure that the signal level in green area Q3) LCD display already show frequency or always receive signal before measuring will affect the device operation A3) Please go to Menu "RF Detect Level" and set 5 or above to solve the problem Q4) How far effectively can i detect a signal ? Close range as in 1-5 feet or can it work further like 5-15 feet ? A4) Radio cannot leave the frequency counter too far, make sure that the signal level in green area when you measuring. Q5) What is the small number after the CTCSS/CDCSS mean ? (see photo) A5) These number is for our technical use only Q6) Will the SF-401plus pick up Color Codes and Time Slots for DMR ham radio? A6) SF-401plus cannot pick up color colde and time slots for DMR radio Q7) What is the minimum digital pulse time required to register with the device? A7) digital mode for DMR radio only, not for other digital device Q8) How to close the attenuator? A8) switch the antenuator button to left hand side Q9) How to close " * " before Digital [SF-103] A9) Press [F2 Stop] and then press [F4 Ent] to close the *, device will back to normal Q10) What is the function of " * " A10) it is a lock function, which mean you can't adjust the gate digital Q11) Hi there how to I calibrate my SF-103 frequency counter it's off A11) *Power On/Off: Power on ,press and Hold down the [Red key] by 3 second Power off ,press and Hold down the [Red key] by 3 second of number count down to 0 https://www.youtube.com/watch?v=3ODZKwtI98U Q12) How can i increase the signal detection range of my SF-401plus? A12) SF-401 design for check strong signal from walkie-talkie. switch to 0 dB is increase the signal. Q13) What is the distance of receive for this SF-103? A13) About 1-3M Q14) Does SF-401plus measure the CB band / I know it states not accurate but what does that mean? I am looking for a wireless frequency counter that is wireless A14) Sorry , We have no idea for choose other brand , frequency counter for 27MHz and AM mode cb radio. Q15) SF-103 works on analog and dmr digital? A15) SF-103 works on analouge and dmr digital. But the DMR mode only for frequency , e.g. 430.025 . without colour code and group detail Q16) Could SF-401plus be used to point a directional cellular antenna A16) it can't Q17) Can SF-401plus /SF-103 test key fob car remote / RF welding machine? A17) It can't , as our frequency counter is design for walkie talkie use only Q18) Hello, this Counter worked then would "not count" when it was powered up again? How do I Factory Reset this Counter? It just stays up in the 2GHz range. A18) power on and hold on Q19) How do you use the CTCCSS/DCS Decoder to deactivate a chip? A19) SF-401plus is design for walkie talkie use only
