The amateur radio used market is one of the best in any hobby. Radios are built to last, many operators take excellent care of their equipment, and the constant stream of upgrades means quality used gear is always available. Buying used can save 30–50% compared to new prices, and in some cases you can acquire legendary radios that are no longer in production.
That said, buying used requires more knowledge and caution than buying new. There is no manufacturer warranty, the equipment may have undisclosed problems, and not every seller is equally forthcoming about condition. This guide will help you evaluate used equipment and avoid the most common pitfalls.
Hamfests are the best place to buy used equipment because you can inspect and often test the gear in person, negotiate directly with the seller, and get a feel for the seller's knowledge and honesty. Large hamfests like Dayton Hamvention, Friedrichshafen Ham Radio, and regional hamfests have extensive flea market areas. Arrive early for the best selection.
QTH.com Swap and eHam.net classifieds are popular in North America. QRZ.com forums and classifieds are another option. In the UK, RSGB Members' ads, Radioworld, and various Facebook groups serve the same purpose. These platforms are used primarily by amateurs, so the community norms tend toward honest dealing.
eBay has a large selection of amateur equipment. Check the seller's feedback rating carefully, read the listing description thoroughly (including what is not said), and use payment methods with buyer protection. Be cautious of listings with vague descriptions, stock photos instead of actual photos of the item, and no-return policies.
When an amateur passes away (referred to as becoming a "silent key"), their equipment is often sold through the local club, a hamfest, or an estate sale. Estate sales can offer excellent prices because the family may not know the equipment's market value. However, the equipment may not have been used or maintained recently, so thorough testing is important.
Your local amateur radio club is a valuable resource. Members often know who is selling what, and buying from a fellow club member gives you the advantage of local reputation and the ability to test equipment before buying.
Before shopping, decide what you want and learn its market value. Check completed eBay listings, QTH.com prices, and the Universal Radio and Ham Radio Outlet used equipment pages for price benchmarks. Know the original retail price and the typical used price range. This prevents overpaying and helps you spot suspiciously low prices (which may indicate problems).
Read the eHam.net reviews for the specific model. This tells you the common issues, known weak points, and what to look out for. Every radio has its quirks — knowing them in advance is invaluable.
Cosmetic condition tells you a lot about how the radio was treated. Heavy scratches, dents, broken knobs, and cigarette smoke residue suggest rough handling. A radio in clean cosmetic condition was more likely well-maintained. Check for signs of liquid damage (stains, corrosion near vents), which can indicate catastrophic internal damage.
Inspect the connectors. Antenna connectors (SO-239 or N-type) should be clean, with no corrosion or bent centre pins. Damaged connectors are not necessarily a deal-breaker (they can be replaced), but they suggest the radio may have been subjected to stress or poor antenna installations.
Check the display. LCD displays can develop dead segments or faded backlights over time. Turn the radio on (if possible) and verify that all display segments work. LED displays are generally more durable.
Examine the controls. Turn every knob, press every button, and flip every switch. Controls should feel smooth, not scratchy or stiff. Scratchy volume or RF gain controls can indicate worn potentiometers (usually an inexpensive repair). Intermittent buttons or rotary encoders are more annoying to fix.
Look at the serial number area. Ensure the serial number label is intact and matches any documentation provided. A missing serial number label is a warning sign.
Open it up (if the seller allows). Look for signs of repair (replaced components, re-soldered joints, non-original wiring), water damage (corrosion on circuit boards or connectors), overheating (darkened or charred components), missing hardware or shields, and modifications (which may or may not be desirable — find out what was done and why).
If at all possible, power the radio on and test it. The ideal test requires a power supply, dummy load, antenna, and another radio to listen to the transmitted signal.
Receiver test: Connect an antenna and tune across several bands. The receiver should produce a clear noise floor, and signals should be audible and undistorted. Check that the S-meter moves appropriately. Try all modes (SSB, CW, AM, FM if available). Check that the bandwidth/filter controls work.
Transmitter test: Connect a dummy load and a wattmeter. Key the transmitter on each band and verify that it produces rated power. On SSB, speak into the microphone and verify that the ALC meter responds appropriately and the power meter shows output on voice peaks. Check that the transmit audio sounds clean on another receiver. Verify operation on all bands — some faults only appear on specific bands.
General operation: Test the VFO (it should tune smoothly without jumping), verify that memories store and recall correctly, check the built-in antenna tuner (if present), test the CW keyer, and exercise any other features that matter to you.
A complete used radio purchase ideally includes the radio itself, original power cable (often with Anderson Powerpoles or bare wires), original microphone (for transceivers), original manual (or a note that it is available as a PDF download), and the original box (nice to have but not essential). Missing accessories reduce the value and should be reflected in the price.
Electrolytic capacitors have a finite lifespan and are the most common failure point in older equipment. Symptoms include intermittent operation, hum in the audio, failure to power on, and unstable or drifting frequency in very old radios. Capacitor replacement ("recapping") is a standard repair for vintage equipment.
LCD displays in radios from the 1990s and 2000s can develop fading, missing segments, or complete failure. Replacement displays may be available from the manufacturer or third-party suppliers, but for some models they are difficult or impossible to source.
Scratchy volume and RF gain controls are caused by wear and contamination of the potentiometer's resistive element. This is often fixable with contact cleaner spray (DeoxIT is the standard) or replacement. Rotary encoders (used for VFO tuning in many radios) can develop skipping or erratic behaviour with age.
Radios using PLL (phase-locked loop) synthesizers can develop unlock conditions where the VFO will not tune to certain frequencies, or the radio shows an error indicator. This can be caused by aging components in the PLL circuitry and may require alignment or component replacement.
The PA (power amplifier) transistors are the most expensive individual components in a transceiver and can be damaged by high SWR, overdrive, or lightning. A radio that produces no power or significantly reduced power on one or more bands may have blown final transistors. Replacement finals are available for most radios but can cost 50–200 USD per device, and installation requires some skill.
Some used radios have been modified — common modifications include the "MARS/CAP mod" (enabling transmit outside amateur bands), receive audio modifications, improved cooling fans, and power output modifications. Some modifications are harmless or beneficial; others can degrade performance or cause problems. Ask about any modifications and decide whether they are acceptable.
Used amateur radio equipment generally follows predictable depreciation curves. A radio that is one to two years old and in excellent condition typically sells for 70–85% of current retail price. Radios three to five years old sell for 50–70%. Equipment that is ten or more years old sells for 30–50%, depending on model desirability. Classic and collectible radios (like the Drake, Collins, and certain early Kenwood models) can hold or even appreciate in value.
Prices vary significantly based on condition (a 9/10 cosmetic condition radio commands a premium over a 6/10 example), completeness (original box, manual, and all accessories add value), included extras (after-market filters, modifications, spare tubes for amplifiers), and local market conditions (prices vary between regions and countries).
Be cautious if the seller is vague about the radio's history or condition, the price is significantly below market value with no clear reason, the seller will not allow testing or inspection, the seller pressures you to decide quickly, the radio has obviously been opened and components appear disturbed, or the seller cannot demonstrate basic operation.
If something feels wrong, walk away. There is always more used equipment available. A bad purchase will cost you more in frustration and repair bills than the money you saved.
To properly evaluate used equipment, having your own basic test gear is invaluable. A digital multimeter, an SWR/power meter, and a dummy load are the essentials. An antenna analyser or NanoVNA is extremely helpful for verifying antenna port impedance. See Test Equipment for recommendations.
Older equipment (1960s–1980s tube and early solid-state radios from Collins, Drake, Heath, Swan, and others) has a dedicated following. These radios can be excellent performers when properly maintained, but they require more knowledge to evaluate and maintain. Expect to replace electrolytic capacitors, clean controls, and possibly re-align the radio. The reward is a radio with character, often superb audio quality, and a connection to amateur radio's history.
For vintage equipment, join a model-specific mailing list or online community (the Drake, Collins, and Heathkit communities are particularly active) before buying. Members can advise you on fair prices, common problems, and sources for parts.
Once you have acquired used equipment, take time to clean it thoroughly (compressed air for dust, isopropyl alcohol for grime, DeoxIT for controls), download the service manual (available free for most amateur radios from mods.dk, radiomanual.info, and manufacturer websites), do a full operational test and note any issues, and update the firmware if applicable (many modern transceivers have firmware updates available).
If the radio needs repair, consider it an opportunity to learn. Many amateur radio repairs are within the capabilities of a handy operator with basic soldering skills, a multimeter, and a service manual. For more complex repairs, professional amateur radio service shops exist in most regions.
