Important notes on power output | |
---|---|
Measuring power output will vary depending on many variables. Our default test-setup consists of a 14-volt power supply, 50 ohm dummy load, and Bird wattmeter reading PeP (peak envelope power). If you are using different equipment, measuring RMS instead of PeP, or have an SWR reading different than shown, you may have different results. The following chart shows an example of power readings for this radio with changes to measurement variables. Final note, the Dosy meter referenced below is directly affected by the SWR readings in the antenna system. You may notice huge differences in power readings from subtle changes in SWR. | |
Bird Wattmeter | |
Voltage | 14VDC |
SWR | 1.2 with dummy load |
Impedance | 50 ohm |
AM Carrier (low w/ 50W slug) | 2W |
AM Carrier (high w/ 50W slug) | 12W |
AM Modulation (PeP w/ 100W slug) | 50W |
SSB (w/ 100W slug) | 42W |
Dosy TC4001 | |
Voltage | 14VDC |
SWR | 1.2 with dummy load - 1.5 with Antron A99 Antenna |
Impedance | 50 ohm |
AM Carrier (low @ 20W scale) | 2-3W |
AM Carrier (high @ 20W scale) | 9-12W |
AM Modulation (PeP @ 200W scale) | 30W |
SSB | 30-35W |
Height | 52mm (2in) |
Width | 170mm (6.7in) |
Length | 250mm (9.8in) |
Current | 10A |
*NOTE* The manual suggests using a 6A fuse, however the stock power cord uses a 15A fuse. This radio can draw slightly over 5A when modulating, we suggest ignoring the mis-print in the manual and using the actual fuse included with the radio. At least 10A, no more than 15A. |
