This will reduce hesthkit possibility of delay. Use a 6 solder lug at AA in place of a 6 lockwasher. Delivery time is estimated using our proprietary method which is based on the buyer’s proximity to the item location, the shipping service selected, the seller’s shipping history, and other factors.

The power losses in these cases are occurring in the cable, but the SWR hm-210 reading will not indicate that anything is wrong. Estimated on or before Wed. A cross pointer meter which reads forward power and reflected power at the same time and also indicates SWR is much easier to use.

Cut off the excess lead on the component side. Parts that are damaged through carelessness or misuse ublletins the kit builder will not be replaced without cost, and will not be considered in warranty. By looking at this same level on the left-hand side of the chart, you can read the dB loss per feet of the cable at that frequency.

SWR reading while transmitter is off. The item you’ve selected was not added to your cart. Solder heatgkit four lugs to the foil. Multiply the total loss by the cable length in feet Then divide by Back to home page. No additional import charges at delivery! These resistance and reactance values change when the transmission line length or frequency is changed. Therefore, many troubles hm-210 be eliminated by reheating all to make sure that they are soldered as described in the Builders Guide.

Reverse power readings are determined, in the same manner, by the circuit consisting of diode 02, capacitor C8, and resistor R5. This is done by finding your operating frequency on the bottom line of the chart, and moving up to find the type of cable used.

Then, push the end of the black wire through hole H until the ferrite bead is down against the component side of the circuit board. Disconnect the transmission line and hm-21002 the remote chassis face down on your work surface.

Please enter a number less than or equal to 1. Merely place the FUNCTION switch in either the or watt position; then read the corresponding scale on the meter scale to obtain the power output of the transmitter. Kits that have been modified, soldered with paste flux or acid core solder, cannot be hm-1202 for repair.

Disregard the Power Meter readings at this time.
