There are many variables in the design of a receiver that can influence this - it does not necessarily mean that your radio is worse than others - in fact, it may be better. A more sensitive radio, a radio with a larger bandwidth or a radio with a fast acting squelch will react to these pulses negatively - but in the absence of these interfering signals may well be better than a radio that does not react to the interference.
There is an interesting NASA report ion some research involving navigation receivers and interference (mostly from FM broadcast sources) which states that the most sensitive receivers where more affected (which makes a lot of sense of course). Partly based on this report my challenge was to make a navigation radio that would be sensitive yet robust with respect to interference. It can be done but you effectively have to throw away the traditional superhet receiver if you want to keep things manageable and embrace new ways of making receivers which avoid some of the issues by fundamental design. Luckily - just that is now possible using some relatively newly released chips and an almost enormous amount of pretty complex maths. As I mentioned earlier - a completely ridiculous effort to produce a simple AM receiver in the most complicated way possible. But once done, bits and bytes are cheap and the result is quite respectable...
