HAMRADIO Tools

This is a collection of libaries and tools I use to do HF QSOs as DL3NEY:

calculate distance and azimuth between locations (given as lat/lon or maidenhead locator): locator and latlon
find DXCC information about radio callsign prefixes: dxcc
retrieve information about a radio callsign from HamQTH.com and QRZ.com: callbook
use the callsign database from Super Check Partial: supercheck
talk to the cwdaemon to output CW on your transceiver: cw
more to come as I have time and need

The tools are written Go on Linux. They might also work on OSX or Windows, but I did not try that out.

Disclaimer

I develop these tools for myself and just for fun in my free time. If you find them useful, I'm happy to hear about that. If you have trouble using them, you have all the source code to fix the problem yourself (although pull requests are welcome).

Functions ¶

This section is empty.

Types ¶

type DB ¶

type DB float64

DB represents decibel (dB).

func (DB) String ¶

func (l DB) String() string

func (DB) ToSUnit ¶

func (l DB) ToSUnit() (s int, unit SUnit, add DB)

ToSUnit converts this value in dB into the corresponding S-unit (S0 - S9).

type DBRange ¶

type DBRange struct {
	From, To DB
}

DBRange represents a range of dB.

func (DBRange) Contains ¶

func (r DBRange) Contains(value DB) bool

Contains indicates if the given value in dB is within this dB range.

func (DBRange) Normalized ¶

func (r DBRange) Normalized() DBRange

Normalized returns a normalized version of this dB range, where From <= To.

func (DBRange) String ¶

func (r DBRange) String() string

func (DBRange) Width ¶

func (r DBRange) Width() DB

Width of this dB range.

type Frequency ¶

type Frequency float64

Frequency represents a frequency in Hz.

func (Frequency) String ¶

func (f Frequency) String() string

type FrequencyRange ¶

type FrequencyRange struct {
	From, To Frequency
}

FrequencyRange represents a range of frequencies.

func (FrequencyRange) Center ¶

func (r FrequencyRange) Center() Frequency

Center frequency of this range.

func (FrequencyRange) Contains ¶

func (r FrequencyRange) Contains(f Frequency) bool

Contains indicates if the given frequency is within this frequency range.

func (FrequencyRange) Expanded ¶

func (r FrequencyRange) Expanded(Δ Frequency) FrequencyRange

Expanded returns a new frequency range expanded by the given Δ.

func (*FrequencyRange) Shift ¶

func (r *FrequencyRange) Shift(Δ Frequency)

Shift this frequency range by the given Δ.

func (FrequencyRange) String ¶

func (r FrequencyRange) String() string

func (FrequencyRange) Width ¶

func (r FrequencyRange) Width() Frequency

Width of this frequency range in Hz.

type SUnit ¶

type SUnit DB

SUnit represents the upper bound of a S-unit in dBm.

const (
	S0 SUnit = -127
	S1 SUnit = -121
	S2 SUnit = -115
	S3 SUnit = -109
	S4 SUnit = -103
	S5 SUnit = -97
	S6 SUnit = -91
	S7 SUnit = -85
	S8 SUnit = -79
	S9 SUnit = -73
)

func (SUnit) String ¶

func (u SUnit) String() string
