Pyramid Swr 14 Manual

The SWR cannot be changed by rotating this knob. The SWR function allows you to determine the SWR or 'match' of the antenna system and transmitter on a specific channel.

The entire process must be performed whenever you want to know what the SWR is on a different channel. The SWR/CAL button toggles the meter between the CALIBRATE and SWR modes. Set the radio to CH1. Press the SWR/CAL button. The radio CAL(ibrate) mode is now selected.

Press and hold the mic PTT (or push to talk) button. Rotate the SWR knob as needed to adjust the meter indicator until it is on the SET mark on the dial. The meter is now calibrated for this channel. While still holding down the mic PTT, press and release the S/RF SWR CAL button to the SWR setting to read the SWR on the meter. This entire process should be done for Ch 20 and Ch 40.

You must go through the CAL procedure for EACH channel before attempting to read the SWR. Changing the SWR requires that the antenna be lengthened or shortened until such time that the SWR can be reduced no further. Typical SWR across the band may be: CH1 - 1.5:1, CH20 - 1.1:1, CH40 1.5:1 or CH1 - 2.2:1, CH20 - 1.7:1, CH40 2.3:1 The 'dip' in SWR on CH20 is typical, as the antenna is the perfect length on only one channel - it will be come slightly too long or slightly too short as you tune up or down from CH20.

The further away from CH20 you go, the poorer the SWR will be. You can 'slide' the dip to any channel you prefer - say CH8. If you tune for lowest SWR on CH8, You might see CH1 with a 1.2:1 SWR, CH8 at 1.1:1 SWR and CH40 at 2.5:1. All are acceptable - sort of.

Many manufacturers say up to 2.5:1 or even 3.0:1 matches are ok, There's no reason a quality antenna can't be tuned for optimum SWR in the middle of the band (CH20) to have less than a 2.0:1 SWR on CH1 or CH40, unless there is a ground issues or bad cable / antenna / connection somewhere. You can view the manual. I hope this helps & good luck! Nov 30, 2012 . I'm not sure I understand exactly what you're doing, but I can tell you how to do an SWR calibration.

You have a three-way switch on the left next to the meter. From top to bottom they are: s/rf (signal/radio frequency), swr, and cal (calibrate). Put the switch in the 'cal' position. Key the mic and hold it. Turn the SWR calibration knob one way or the other until it lines up with the triangular mark in the upper right corner of the meter. Azusa The Next Generation Zip more. Then put the switch in the middle (swr) position and key the mic again.

I bought a Pyramid Phase III SWR,Power. PYRAMID PHASE III REGULATED POWER SUPPLY Manual & Schematic. Pyramid SWR-14 Meter questions. PYRAMID SWR —— 14. CAUTION 1 DO NOT SWITCH ON THE TRANSMITTER UNLESS BOTH ANTENNA AND TEST ME. TER ARE CONNECTED I ~. 'transmtt” button unless both cables are connected I. SWR/STANDING WAVE RATIO MEASUREMENT. Set the right-hand switch to 'FWD.

It will give you a reading on the swr band on the meter. The lower the better: 1:1 is perfect, 1:2 is OK at best.

Any higher (especially over 3:1), and you have a problem that can't be fixed by tuning. You have a bad antenna, a bad coax or a mismatched pair of antennae if you're running co-phase.Hope this helps. Jan 15, 2011 . I actually have 2 12' type s's and i did the same thing just wanted a cheap amp.

I went on ebay and bought a pyramid 1600 super blue series amp. Its 1600 watts and ive also hooked it up to type r's and it POUNDS!!! Ill copy and paste the website where i got mine from on ebay. If you tune it right it'll make it so you cant breathe inside your car. Nov 11, 2009 .
